I get about 50mpg@70mph on the highway. This is way better than any Hybrid or Smartcar and it's way cheaper too. And, oh, I forgot to mention, way more fun to drive.
Wow at 70mph? I got 50mpg doing 65 I figured any higher I wouldn't get that great of mileage...I guess it depends on how far you're driving. If its a short highway trip I highly doubt it would be that high but congrats on the mileage, that's cool! It feels good doesn't it?:laugh: :thumbsup:

I watched the shifting on the auto much closer the past couple days and have noticed when accelerating the transmission shifts before 2000 rpm and when decelerating it shifts closer to 1500, so I'd try shifting a lot earlier than you are now.
thanks VD22 i might try that...we shall see..:w00t:

Be careful...shifting too early can also burn decrease MPG...there is a sweet spot...someplace between shifting late and shifting early...one must not assume that keeping the RPM's down and shifting early will always increase MPG.

The world was out to kill my FE on this tank.
1) I drove with my damaged door for 10 days, which hurt the aerodynamics.
2) The body shop drove the car hard.
3) The wife used the a/c twice.
4) I had several slow trips over the mountain due to the entirety of the highway being re-paved in sections.
The end result was 47.562 MPG, which was my worst tank in a few months.

Well here's an interesting observation... I knew that air conditioning was quite a hog of engine power, and as a result, fuel, but it's a much bigger difference than I thought! Over here AC is more or less a necessity, but I've trying to do without it as much as possible, like int he evening, or on cool rainy days. Firstly you can feel a big difference in engine power especially at low revs, it feels a lot smoother, much harder to stall. And, so far, I have not yet finished this tank, but the meter's at the halfway mark since a few days, I have 270km on the tank, normally I only have about 200 at this point. So, it looks like I may finally get to 400km before refilling (normally I refill at about 330km, i.e. ~24MPG), which would mean close to 30MPG... Wait and see...
It is said here (please see link below), inter alia, that AC can increase fuel consumption by 20% or more in city driving. If you do not have time for the whole page, please go direct to the paragraphs captioned "Are you willing to pay a fuel penalty for all those extras?" and "Options for fuel efficiency":

well the crappy thing is, now my fuel gauge has dropped two bars in one day, I just reached 300KM and 2 bars left. I know, it's somehow a feature of this fuel gauge that the secon half drops faster than the first, but this is ridiculous :laugh: or maybe my messed up exhaust pipe had something to do with it, but I doubt that...
Sorry to learn about the sudden fuel gauge drop and the tail pipe issue. I have read your thread about the incident. All roads are hazardous:frown:!
Back to fuel economy, you are very right, the bars at the lower parts of the gauge do not last as long as the top one. My experience is that except in some extreme cases, each of those bars (except the last one about which I have no courage to find out more:wink:) gets about 50-65 kms in city driving and more in highway driving. As you and most users of this thread are aware, it depends on many factors. Long term averages are more reliable.
All the best and drive on for fuel economy!

ok, here are the numbers from my next fillup-332.1 miles on 9.375 gallons of gas=35.424mpg. really drove conservatively-used the a/c very sparingly. this is suburban driving southside of chicago. typical lots of stop lights-a variety of speeds-no expressway driving. i can not see a way to ever get to 40mpg unless i throw out my rear seat-spare tire and lose my once in awhile passenger and lots of weight myself.

We all have much more horsepower than we need. With the Yaris' weight we could easily get by on less than 33 peak hp.
You don't have to get there fast. You just have to get there.
Hence I would rather have the 1.0L than the 1.3 or 1.5. It would be even better if they offered a 1 cylinder at 300cc or so, especially if it were part of a hybrid drive train.

I generally get anywhere from 29-32mpg, 100% city driving. I'm taking the yaris for a 14 hour drive to north-east Quebec in the winter, I'm interested to see how many mpg I get. I'm really surprised how many mpg people are getting here. Also some good tips on saving gas, but 2000rpm while accelerating? I always tend to get real annoyed when someone in front of me takes a few minutes to get to the speed limit. I have the mentality that a car is meant to use gas and can't get around it, but I guess it's always fun to save at the pump too. When I used to own my 94 Probe GT I went through gas like crazy...had to be premium, too, or else the engine starts to bog down and eventually start to detonate. I think with my probe I averaged 14-18 mpg, that was for the 2.5L V6 with the 5speed. But then, I'd accelerate in first gear to 6-7000 rpm at most lights just because I could. 6000 would usually get to the speed limit, so thats usually where I stopped.

But that's a VW, they are expensive, boring and bad quality!
And 78 mpg isn't true also, ok behind a truck maybe with a little luck you get that mpg.
But in the other hand petrol in the States is getting more expensive i realize that but it is nothing if you compare it with Western Europe!
Petrol here costs 1,50€/ L,
that's 5,67 €/ Gallon,
that is 7,80 USD/ Gallon
I don't know what you guys pay for petrol but i think it's 2 times cheaper?!
As a matter of fact I once drove a VW Lupo as a company car when I was working in Germany. It was easily getting 75 MPG (3.2 Liter/100 km) Diesel without any tricks. I can't speak about the quality, but it seemed to be okay to me. They used titanium to lower the weight of the car. That's why the price was too high at about $23,000.
And then again the Lupo is completely overpowered with a top speed of 105 Miles. I wonder what the mileage would have be with a sensitive engine.

There are a lot of VW's here and we have a very strict policy here, the cars have to be tested every year.
Also windows that fall into the doors by a lot of VW's, electronic problems, broken almost new engines!!!!
And the mileage you get in a Lupo 3L is tested here in Europe and it didn't comes even close if you want to go normal with the rest of the traffic.

I have also had a Honda 600. If I remember correctly, it was a car with a two-stroke engine. In the place where I lived then, I think it was called Honda N600. Just can't remember clearly. It was a frugal car but I believe it won't pass the stringent exhaust tests of today.
Also, I have been told that small engines enjoy very good fuel economy in city traffic but loose their advantage to slightly bigger engines at highway speeds. Correct me if I am wrong.
The small Honda may have given me good memories but rationally, it should possibly be inferior to the Yaris in almost every important respect.

It was a 4 stroke, air cooled, 2 cylinder....and yes it was inferior to any car built today, but fun. I always got 30 mpg, town or hwy, because of leadfoot disease. I saw one win best mileage in a rally at 60 mpg, but was disqualified because of emissions....I think the govenment is wrong using parts/million in their standards, it should be parts per mile---then we would really get rid of the large displacement engines (a 454 ci engine puts out 12 times as much exhaust as the 600cc). Yes, I think it was a n600, they had a sedan which was a total block and the coupe which was a smoothed block.

It appears from your spread sheet that your mpg numbers are very good. If you are not hypermiling (frankly, it appears from the numbers that you are not), you must have been driving very conscientiously. Your lead foot disease must have healed completely.

Re: Posts #1541-1542.
..... Your lead foot disease must have healed completely.
The first 1.5 months it maybe came back for a while....but it may not have been broken in, and at that point I put on the Megan springs and aired the tires to 40 psi. As far as hypermiling the only thing I do is (most of the time) I coast down 1 hill (about 1/2 mile) in neutral going and coming from work, 40 mile round trip. Most of my miles driven are 2 lane blacktop at 55-65 mph, but I've taken 2 1k trips at 70-80 mph.
I'm happy with the automatic, although I'm sure the 5sp would do better.

With my manual Yaris, bought used with 8300 miles on it two weeks ago:
Tank1:
37.8MPG, n00b driving, 80% city, traffic jams. 170 miles. Tire pressure 32psi.
Tank2:
277 miles, 35.2MPG, 70% highway going 75-80mph, trying to "hypermile" by turning off engine in intersections and tailgating trucks/trailers to lessen drag. Tire pressure 32psi with 28psi on right front tire, causing right turning tendency and unstable handling.
Tank3:
402 miles, 40.5MPG, 75% highway, one 70 mile trip to the top of a mountain (8000 feet altitude, 6000 feet altitude gain/ascent), three 52-mile trips to work, one 122 mile trip to another place of work and about 5 trips in city stop&go traffic. 60-65mph even on interstate, turning off engine as often as I can, including in downhill traffic and rolling into my parking spot. Tire pressure increased to 38psi on all tires, noticeable reduction in rolling resistance and improved handling.
Tank 4 - filled today: Cost for filling up: $30.29. 9.917 gallons, which means I had well over a gallon left. In the future I will drive to 400 miles and then start looking for a gas station somewhere in the next 50 miles!! (still had two bars left when I filled it up at 402 miles).
I drive about 2700 miles/month.
With my Yaris:
- The 52 mile round trip to local place of work costs $4.
- The 177 mile round trip to distant place of work costs $13 driving 70mph, $15 if keeping up with traffic at 80mph.
- Cars are constantly stuck behind me trying to pass, constantly tailgating and signaling for me to speed up.
- My estimated monthly gas expense is just around $210/month.
- I will visit the gas station five times less per month than before. This translates to less soda, ice cream, hot dogs etc. I will lose weight because of Yaris!:bellyroll:
With my old Ford Explorer V8:
- The 52 mile round trip to local place of work would cost $12.
- The 177 mile round trip to distant place of work usually cost $27 dollar if I drove 5 below speed limit - $32-$35 if I followed the traffic flow at 80mph. Minimum pay at this place of work is $40/day if activity is low, so there goes my profit.... I would be at the gas station every day to have enough fuel for the round trip.
- I drove up the mountain mentioned above, with over 3/4 tank of gas (about 16-17 gallons). I drove down the mountain 70 miles later with tank empty light flashing!! (engine didn't handle increase in altitude very well.....).
- Cars would still be stuck behind me due to my slow driving, but would not signal for me to get out of the way.
- My monthly gas expense was $550/month (using premium gas to obtain higher MPG - cost would be slightly higher using regular gasoline which in my experience gave significant reduction in MPG).

You just opened up a flamefest-worthy topic, but I'll bite. First let me say I am not a scientist nor an automotive engineer. I'm just a Joe Six Pack that did his own testing, using his own driving style.
As most of you know, my driving style is feather-light, as is the hypermiling way.
I tried 89 octane for 3 tanks and lost 8% of my MPG.
Yes, my ignition timing didn't retard as much with the higher octane (on average 89 octane was 6 points advanced), and there was a small amount of more torque available (i.e. I could climb Mount Rose to Thomas Creek in 5th gear WOT instead of 4th gear 80%), but it simply used more fuel to accomplish these things.
87 octane and a light driving style is where the efficiency is at.

It can vary a bit in the U.S., but I'd say that at least 90% of the stations in the country serve 87 (regular), 89 (super) and 93 (premium or supreme) octane, with most vehicles capable of working with the 87.
Like just about every other measurement system, the U.S. uses a screwed up one when it comes to measuring octane. See: http://en.wikipedia.org/wiki/Octane_rating#Measurement_methods

To me the only reason to use it would be if you had a real high compression 'toy' that would require it all the time to run....or a turbo that you wanted to kick the boost up ocassionally.
Otherwise.....+1 with PK198105

Fuel of octane numbers up to 94 are quite widely available in the Greater Vancouver Area. Petrol Canada and some other gas stations everywhere sell them all the time. However, like in Toronto, as you have said, 87 is still the standard (regular) fuel.
IMHO, cars need to be designed to take advantage of high octane fuels in order to really benefit from them. As far as I know, the Yaris is not designed to take advantage of very high octane numbers. I have tried a tank of octane 92 which is high but not exceedingly high and have not noticed any significant difference in terms of mpg. Yet admittedly, a short period of experiment in an uncontrolled environment can hardly be regarded as conclusive. Anyhow, the car's computer, aka ECU will take care of any slight change in the octane number of the fuel. Whether high numbers up to, say, 113 are still within or already outside the computers manageable range is beyond my limited knowledge.
As many of us have noticed, this is a much debated subject (NB: this is an understatement:wink:) and I would prefer to leave it here. The bottom line is using slightly higher octane fuel will very probably not do harm to the engine of the Yaris. Honestly, though I cannot remember where, I have read articles/posts saying that a car that requires regular fuel may benefit from a higher octane number when its engine is old and under-maintained, or when it is required to work very hard to carry heavy loads or drive up very long and steep slops.
In short, I tend to believe the two gentlemen above:smile:.

One of my friends has a 1997 acura TL with the 3.2 engine auto trans, he says he sees a 40km difference between a tank of 87 and a tank of 91. Another friend has an '89 mustang GT cobra, and his engine gets real bad knock if he uses anything except 91 and 94 octanes. Even my own experience when I had my 94 Probe GT 2.5L MTX, I would see about 50kms less on a tank of 87 octane and there would be a noticeable loss in power and the engine would bog down sometimes with 87 if I put 100% throttle from a stop. The one thing I don't like about buying premium is the mark up in price. I was reading an article somewhere saying that 91 only costs the gas stations 2-2.5 cents a litre more than 87, but on average they charge 10 cents a litre more for 91 over 87. But then if 91 was only 3 cents a litre more, I'm sure most people would be buying 91. All in all, from what I've read, cars designed to run on 87 should be used with 87, as the higher octane won't get power worth the cost over 87.

On average, I can get between 620 and 650km per tank...which works out to be in the 40mpg range...give or take, since It's a 42L tank(roughly 11 gallons)

It's pretty good...well, when construction workers aren't working on main highways in the middle of summer! So yeah, it might not be a smooth ride, even in a Yaris. :laugh:
I am going to work on my "lead foot" problem. Quite a few Yaris drivers have told me they can get close to 800km on a tank..which is closer to the 50mpg that toyota lists for the Yaris. For once, I'd like to see my numbers get that high! :laugh:

Good additional info! Keep posting your data as you go, please! Just not sure Toyota says 50 mpg:tongue:. Must be an all highway number. Anyway, I think amongst non-hypermilers, only UncleYaris (a fellow member) has once posted an mpg number exceeding 50 (refers to Imperial gallons). Forgive me Uncle, if you are in fact a hypermiler or if I remember your numbers incorrectly.

Yep, it was 40 for city driving, and 50 for highway driving. Usually, i'm about 70% city, 30% highway.
I'm actually leaving PEI and moving to Saint John, New Brunswick tomorrow(Thursday), so I'll drive a little bit slower to get there, to see if I can get any better mileage (The speed limit is 110km/hour, but I usually do 125 or 130...I'll try sticking around 110 and seeing what happens).
Wish you all the best for the move!
Safe and happy and ECONOMICAL motoring!

I took the Yaris in for an early oil change last week and they lowered my psi from 40 to 32. I put the car to 40 almost right away, so I forgot how much better the ride was at 32. I could tell instantly they had lowered the psi, because the car felt like it was in sand off the start and the cornering was really bad. Tons of sidewall flex. The ride was noticeably better over bumps as well.
I decided to leave the tires at 32psi to see what kind of difference I would get in fuel economy. I'd say it made no difference. I thought for sure it would, because it sure felt like I had to give the car more gas to get going. I put it back to 36psi now as I do not like at all how the car handles around corners at 32psi and I'm also not a fan of the harsh ride at 40psi.
I still got:
5.167 l/100km
54.67 imperial mpg
Or
45.52 US mpg
on over 500kms of driving at 32psi.
My overall average is actually worse than this, but that could also be because the car is still breaking in, but I'm averaging 5.254 l/100km, 53.76 imperial mpg or 44.77 us mpg after 8 tanks and about 4400 kms.

OK, I know, not representative for the time being, because it the first time I have refuelled it...

And currently -after 1 1/2 weeks owning the car- my board computer says 7.0l / 100km. But due to the rush hour I mostly drive slow up to 80km/h - just sometimes up to 120km/h.

As I have been suspecting, the Yari in Europe are fitted with an onboard computer, which can help improve fuel economy by providing virtually instant feedback to the drivers so that they can know how do their driving styles affect their cars' F.E.
Thank you joyts!
to give you guys an update, just finished a 4200km road trip from Vancouver to Yellowstone National Park and back. Total overall average was about 6.1km/100km for the whole trip, or 38.5mpg. Not a fantastic number imo, but taken into account that 1/4-1/3 of the driving was done at 110km/h-130km/h (70-85mph), it was to be expected. I drive a 5dr auto liftback, had my fiance and myself in the car with the rearseats folded down and the back packed with camp gear. Even managed to fit a wedding dress in the back on the way home :)
In Yellowstone Park, we saw a fantabulous reading of 405km with the 4th bar of gas just expiring from a regular fill up, on the way to a 700km tank! I usually read about or just under 300km at this point when I am commuting to work and driving about in the city. I attribute this to travelling at speeds of 70-85km/h (~45'ish mph) and longer trips than typical city driving, although we did stop, start and go to see all the different things and wildlife in the park.
This was not my ideal choice in roadtrip vehicle, but her car was in the bodyshop due to an accident. The versatility of the hatch was great, we would have preferred to have the privacy of her trunk though. My lowering springs provided a decent but stiff ride. The only thing I really wished for was cruise control, but life goes on. We found out that it was a great roadtrip vehicle for the future, for the two of us anyways, and came up 20% under our planned fuel budget for the trip if we were to use her car!

Thank you Ron for the vivid description.
I believe the 38.5 mpg number you quoted refers to the US gallon. It is perfect to quote mpg numbers in US gallons terms but for additional reference purposes I would like to add that 6.1 liters per 100 km should be about 46.33 miles per Imperial gallon, good considering the load that you carried and all other factors that you described in your above post.
You mentioned something about a wedding dress. I wish to say "Congratulations!"
Also, nice pictures!

The 2008 MPG numbers are lower because the EPA has changed their testing to be more like how a country full of aggressive, testosterone-infested, jerk-headed and inattentive drivers drive rather than how intelligent, level-headed and attentive people are expected and intended to drive.

So basically, more realistic mpg then? Seems like the better idea, nobody who would drive normally would ever get the mpg most companies claimed their cars to get. The most mpg I've calculated on the Yaris for one tank of gas was 32mpg. Refilled at 1/4 tank, forget how many km's but it was 100% highway.

sorry, but i think its B.S. when people say "no one can drive normally and get posted mileage figures" or "we need more realistic figures."
on this forum and corolla forums, there are tons of people who drive their corollas and yarii "normally" (that is which minimal effort, just driving reasonably) who get or exceed the pre 2008 mileage figures.
i think MOST drivers are in denial about their driving habits. some people may have gotten cars that are mileage "lemons", but those are few and far between.

You would ditch a car if it did not get the mileage advertised??? How did you pull that off at the dealer. Did they actually take the car back or penalize you on miles, depreciation and the like?
My 96 Ford Aspire 1.3 ltr did anywhere from 37-42MPG in summer and 34-38MPG in winter. I assume the warm ups and cold did that. The hotter it got, like over 85Deg, the better mileage it got. Hate to see it go. Bought it for 300 bucks, put on 70K and sold it for 500. People were having bidding wars at work to get that car from me. Took care of it and did good maintenance on it. It leaves tomorrow.

Hey most people who say they can't get the listed milage figures, have No Idea on what their driving style really is ! They don't seem to look way down the road at all .The clueless slam on brakes just when they get close to a light , nail it when it turns green just to slam on brakes agin a block down the road at the next light , these are the same people who creast a hill with their foot in it then hit the brakes & stay on the brakes , half way down the other side of the hill . These people are the ones on yer ass following way to close, hitting the binders & gas petal in rapid order all the while Yakkin' on the cell & flashing their lites at you just cause you got 2 M/T car lengths in front of yourself . Now i'm no pussy when when it comes to driving , I nail it when i have to, pop off the line when needed to change lanes / pass someone . but I am aware of what is going on around me & in front of me . My brakes last a long time . a clear sign that i drive Smart ! OK, :flame: Rant Over !
I agree to some salient points raised in some of the above posts and appreciate members' interest in the subject of this thread.
Most people who regularly visit this forum/thread know why some people don't get good fuel economy. In fact, as far as the Yaris is concerned, if the goal is just to achieve EPA rated fuel economy, particulary the numbers that have been made more "realistic" recently, a driver just has to follow the free advice published widely by concerned parties all the time (http://www.google.ca/search?sourceid=navclient&ie=UTF-8&rlz=1T4ADBF_enCA234&q=fuel+economy+tips). Basically, the guidelines consist of steps more or less like those shown here:
http://retail.petro-canada.ca/en/seasonalarticles/1687.aspx
There may still be many other sites that offer very similar advices. Some links have already been suggested in several previous posts here.

I already know what my driving style is. Sometimes I am in a rush so I do gas it and I don't like people passing me so I go faster to keep them from passing. I don't slam on the brakes a lot though. Just reasonably normal stopping. However, I have always gotten the posted city mileage.. except once when I wasn't the one driving. I always drive city and it's always 35mpg so it's accurate enough for me.

:thumbsup:Good to know! Your post confirms my observation that one does not have to exert undue efforts to get the EPA rated fuel economy. One just has to follow the guite general guidelines suggested by my humble self and other members here time and again. Thank you! As far as not letting people pass you, do it as you like and as long as it is safe:smile::wink:. Your results are already quite satisfactory and from what you have described, it seems that you only have to pay a little more attention to the various fuel saving techniques to accomplish an even better result. Shouldn't be difficult. Also, "my" Yaris is now driven by my wife more. I do not have absolute control over the car's overall F.E. Yet, I have to let her drive. More mileage on the road generally means better safety.
Safe and happy motoring to you and everyone!

well, it's more like when the lanes are turning into one lane and I can tell this person who has been behind me this whole entire time and they suddenly speed up to try and pass me and I know that they are going to get right back to being slow once the road has merged. That's usually why I do it. Other than that, I'm nice enough :smile:

You are probably right. According to P.178 of my owner's manual, ethanol up to 10% or MTBE up to 15% should be acceptable. The descriptions about what fuel to use are actually found on P.178-179. My car is a 06 RS Hatchback (Canadian model). I think the manuals for other Yari should probably contain similar descriptions. They are too long for here and I recommend that interested members read their own manuals for accurate and detailed information.
BTW, P.218-219 of my manual are about how to get good fuel economy and help extend the life of the car.
Goalie
09-03-2007, 12:04 AM
All fuel here is like 10% ethanol. Unless you go WAY up in northern MN or WI. The E85 is like it says, at least 85% Ethanol. We went to South Dakota last summer in the 06Camry, got like a 3 MPG increase with the SD non ethanol fuel fill ups.
We still have 100% gasoline (no ethanol) here in BC. All my mpg numbers quoted previously referred to 100% gasoline. Well, may be not 100% because there are additives in them. I don't know the details.

I personally think that it is good to know how some of the rivals of the Yaris perform:smile:. The Civic is a very strong rival but its fuel economy is not as good as that of the Yaris. Even the Fit is slightly behind the Yaris when it comes to F.E.

I agree, I just had my worst FE by far on a tank and it's because I was going 120km/h with the A/C trying to stay ahead of the insane long weekend traffic using e10 gas. We avoided the traffic, but I got 5.889 l/100km over that 448kms of Highway driving.
Currently in Canada the Yaris Sedan Auto is rated at 5.6, so you have to definately drive outside of the bounds to not get the epa.
Mohawk/Husky uses approx 10% Ethanol in BC.
True, I have tried Mohawk in my former car. Didn't give me good fuel economy and starting took a couple of seconds more to crank (may be for my car only). Otherwise not too different from the regular stuff. When I said "we still have" (Post #1591), I meant we could still find:smile:.

One thing I've noticed using the SGII and different driving styles and road conditions:
The ECU seems to adjust/tune the performance to the style and conditions of driving over a period of time...for example, if I go from Providence to Boston and back on a warm summer day, and do 70 to 80 MPH, my gas mileage will be in the low 40's that day.....then the next day, same weather, same route, if I semi-hypermile the FE will only be a little better - mid/high 40's....but the following day it'll be back up to 52 - 55 MPG. I've noticed this about a dozen times this summer. The same thing seems to happen when and after rainy weather impacts the FE. The conditions of the previous trip seem to affect the FE performance of the current trip. Could it be that for many drivers, the capability of realizing this really high gas mileage with the Yaris is never noticed because it takes a couple of days of conservative driving under good conditions before it happens?

Also, we have encountered a lot of road works which created traffic jams. We always drive for maximum safety and comfort but do not waste fuel unnecessarily. In essence, we drive the Yaris like it is a family car and in that sense, the fuel economy numbers should not be too different from those of a typical common Yaris user.

I agree.

I do share your observations. I have been suspecting that I might have been too subjective but now I am more inclined to think that the ECU remembers things.

most al cars with FI do this. because the computer sends info for how much output from the injectors it wants. thats why if any of you ever go on a trip that first tank is not the best...the second and subsequent tanks are...everything is calculated from how much throttle to o2 temps....

my latest tank 406.2 mi/9.16 gal=44.34 mpg--identical driving pattern to the previous 4 tanks. (oops, i just remembered that i changed the tire pressure from 32 psi to 36 psi before this tank, so that may be the reason for the increase)

Due to my usage of advanced efficiency techniques my mileage in the city is the same as it is on the highway. In the city I have to accelerate many times over short distances due to stop lights and such but that's about the only time my engine is actually running. On the highway the driving is much lighter on the throttle (lots of pulse and glide, never over 55 MPH, etc.) but my engine is running about 98% of the time in order to maintain a speed.
The two sets of techniques end up at the same mileage every time.

Thank you all friends for the discussion about fuel economy in ctiy traffic in the previous posts.
IMHO, as far as fuel economy is concerned, the Yaris is basically designed with city driving in mind without losing sight on the possibility of not infrequent highway trips. I base my opinion on the fact that whilst the Yaris gets practically the best fuel economy in city traffic among cars in the same class, yet on the highway, its F.E. whilst still good, is no better than that of its heavier sibling, the Corolla, with a bigger (1.8 liter) engine. Here are the ratings:

My wife and I drive our Yaris not too differently from any ordinary person driving a family car, in the city and on the highway alike, and our mpg numbers are comfortably above the EPA's average rating. Note that the traffic that we drive in is by no means smooth. The car carries two people plus belongings most of the time. The sound system and the AC are also on most of the time. We always drive for maximum safety and comfort, though fuel is not wasted unnecessarily.
I believe fellow members here can all achieve better and better results as they gradually become more and more fuel economy conscious. I wish to encourage those who have not yet been enjoying the good fuel economy that can be expected from a Yaris (in city traffic for the purpose of this discussion) to try harder. Fuel economy conscious driving is not boring and is in fact very additive. Once one starts, one will try to do better on every occasion of driving. There are lots of fuel saving tips here and everywhere on the net (but to state the obvious, please note that there are always risks associated with net surfing). Here is a page of tips that I have casually found, just for an example:

swng, i think the data you cited disproves your point. the yaris average from actual drivers is 35.1, while the avg for actual corolla drivers is 31.2, so the yaris is a 12.5% increase over the corolla based on that. looking at the chart from actual yaris drivers, many of the very highest mpg figures come from tanks that were primarily highway. my tanks (5 speed yaris) have been more highway than city lately, and im getting 4-5 mpg's more than i ever achieved with my 5 speed corolla over the same routes.

Thanks for the response.
I was only referring to the mpg numbers for city/highway driving in the new EPA official ratings and nothing else. The Corolla and the Yaris are both rated at 35 mpg for highway, with the Yaris getting a better number for city traffic. The Corolla is heavier and equipped with a bigger engine. On the other hand I respect the fact that you actually get good mpg numbers with your Yaris on highways. I feel happy for you.
I do not know why on the EPA site, both the Yaris and the Corolla get 35 mpg for highway. Please note however, that the EPA has strict rules about what is "highway driving" as opposed to many individual drivers' own perceptions. Anyhow, I cannot dispute the EPA ratings because I have nothing solid enough to base on. On the other hand, I find that your points are moot and are worthy of further discussion/observation.
Of course the Yaris' fuel economy is good on highway, as I have already pointed out. I was only trying to follow up the discussion in a few previous posts by some fellow members who felt that in city traffic, the Yaris was not performing well enough for them fuel economywise. I was proposing that with its design (I meant characteristics), the Yaris should in fact do well, and be better than other comparable cars, in city traffic.
In a vague attempt to explain why despite both models get 35 highway mpg according to EPA, more Yaris drivers report good highway F.E. to the EPA site than Corolla drivers, as you may have implied (I admit I have not gone through all the data on that site and please forgive me if I understand you wrongly), I would say that it may have something to do with why certain people acquire certain cars. You know, people choose different cars for different purposes and understandably they drive in different styles. As for me, I have bought the Yaris for, inter alia, its good F.E. I tend to believe that Corollas are more likely used as primary family cars (for e.g. taking children to school and groceries shopping etc.) compared with the Yaris, which I believe are more likely used by single/younger people as a commute/pleasure car (but not without significant exceptions on either side). This may give rise to a result that Corollas may on average carry more people and other loads. In the absence of proof that Corolla and Yaris drivers drive with the same/different styles under the same/different conditions, I tend to treat the new official EPA rating (as opposed to the F.E. numbers uploaded by individual drivers to the site) as relatively more objective because at least EPA rate cars under same rules and conditions. I think that the collective results of the individual makes/models' groups of drivers are more appropriate for further but not basic reference. To quote an extreme hypothetical example, I think an expensive big car like a Mercedes S Class is less likely to be reported as more fuel economical than the Yaris on the EPA site when it comes to individual drivers' reports to that site, partly and mainly because it in fact needs more fuel to run but also partly because a typical S Class driver will less likely (but not without exceptions) be a hypermiler, or a very frugal driver. On the other hand, there are obviously some Yaris drivers who are hypermilers or frugal drivers. So when the drivers' results are uploaded to the EPA site, the average mpg numbers for those cars you can see will be affected accordingly by such trends.
In summary, I referred in my previous post only to the new EPA official ratings for the Corolla and the Yaris, both being 35 mpg for highway but the Yaris has better city F.E., as a point of interest. I referred to those EPA ratings to illustrate that in fact the Yaris should be quite good for city driving as far as F.E. is concerned. I may or may not have proven my point successfully though, yet I definitely enjoy the meaningful discussion. For sure, I am not trying to draw a definite conclusion about the two models' F.E. More views from knowledgeable people like you are always welcome.
I apologize for this verbose reply and thank you for contributing your views and sharing your experience, which have high reference values in their own right.

Okay, Bailout, please to be explaining the techniques for city driving. Now that school has started for my kids, I do a lot of short distance driving with loads of stop signs, traffic, short red lights, etc. Only once with predominantly city driving have I been able to get 34 mpg (note, I've had no problem getting the high 40s for hwy driving), and the current tank looks like it'll end up at around 31 mpg. So, please, tips on how to get this number up. Thanks!

So, please, tips on how to get this number up. Thanks!
Please see the stickied efficiency thread at http://www.yarisworld.com/forums/showthread.php?t=5979 as it covers everything I do. To be more specific regarding city driving I:
- Make use of my block heater every chance I get, carrying an extension cord to plug in at the homes of friends and family when we visit. I also have the ability to plug it in at work. Between this and errand organization it's a rare day when I do a cold start.
- Never speed.
- Never run the a/c, opting instead for window tint, a sun shade, window deflectors, keeping the windows cracked a bit, and a homemade ice vest for the truly miserable times.
- Never get above 2,000 RPM in the city.
- Use the lowest gear possible to maintain a speed when needed (i.e. 4th gear at 25 MPH).
- FAS a whole lot, basically slowly accelerating to the desired speed between known stops (i.e. stop signs, long lights, etc.) and then cutting the engine ASAP and coasting a great distance to the stop.
- Keep the engine off at stop lights, construction stops, drive-thru windows, etc.
- Park way out in the parking lots so I don't waste fuel looking for a space, and can FAS all the way to a space and park face-out.
- Use the DWB technique in combination with DFCO and P&G or FAS/P&G wherever possible to deal with red lights or lines of traffic.
- Combine all my errands into one trip, starting with the furthest one and ending closest to home.
- Constantly assess the road ahead for several blocks in order to have the time to make any needed lane or speed changes slowly, deliberately, and well ahead of time.
- Use my SGII to help keep myself dialed in.
- Try to stay informed of road work/construction areas and route well around them.
That's about it. :smile: Now you know why I say that, in the city, my engine is only running about 30% of the time. I know it sounds like a lot but by adopting and becoming comfortable with just one technique at a time, over a few weeks it all becomes second nature.

Yeah, but none of what you've written can account for 20 miles per gallon; is it because my car usually has 3 people in it? Can an extra 200lbs take away 20 mpg? Is there a difference between city driving and CITY driving? I must be missing something. I already do DFCO; I don't FAS, though, although I try to DWB, but on a steep hill going down, you either use the brakes or crash, plus, again, that can't account for 20 mpg. Any thoughts?

Although every change I've made added to my MPG numbers by far and away the largest item was FAS. If the engine isn't running it isn't using fuel. That's as MPG-friendly as it gets.
To give you an example of how FAS works for me let me tell you how I drive home through my neighborhood. Keep in mind that the higher tire pressures I run really help with decreasing rolling resistance, so I can coast much farther without losing much speed than someone running their tires at 32 PSI.
I've already been FAS'ing long before my exit from the highway, so when I get to the bottom of the off-ramp I brake at the light, which is usually red. I wait for the traffic to pass and once I see an opening I start the engine and lightly accelerate to the speed limit of 45 MPH, unless the next light a short distance away is red in which case I only accelerate to 10 MPH and then FAS again.
Once I reach 45 MPH I FAS and coast the next 3/8 mile to the turn onto the avenue that goes to my subdivision, and continue the FAS through my left turn onto that road. Once I'm on the avenue I can see that shitty light at the Starbucks/Home Depot complex, and if it's red I just keep coasting at like 10 MPH while I time the green. Once it's getting close to green, or of it was green to begin with, I start the engine back up and lightly accelerate to 35 MPH, then FAS the next 3/8 mile to a stop sign.
As I brake at the stop sign I start the engine up just as it's my turn to traverse the 3-way intersection, then accelerate back up to 45 MPH again. From this point I go into my last FAS for a total of a 1/2 mile that goes to my entrance road into my subdivision, then has an immediate left, then a right 100m later, then 100m to my house, finished by a left turn and a 7-9 MPH coast right up the driveway and into my garage (the trick is to start the garage door opening from a ways back).
The total distance driven in this scenario is about 1.5 miles containing moderate traffic, 3 lights and a stop sign, but my engine was only turned on for about 3/8 mile of it despite me keeping up decently with the traffic patterns.

That it does, but a new starter - which I can install myself - costs about $40. FAS'ing saves me more than that in fuel costs each month.
I don't expect it to be much of a problem in the future, though. Most starters used by Toyota are good for around 17,000 uses, which should last me about 3 or 4 years. I'm still on the stock starter and it's 7 months old now

Wow that's intense! Isn't there concern for safety? Like what if you have to suddenly accelerate or whatever? Also in some situations you have to accelerate hard for "safety" reasons meaning to get out of the way or get in a lane, knnow what I mean? Even if your going on the on-ramp for the highway you have to accelerate even faster than gradual sometimes for "safety" of you and others so they don't rear-end you or have to slow way down and almost rear end you. Also, how do you deal with rush hour driving like that and impatient people? Tailgaters? I hate rush hour cause well, its rush hour and it kills my mileage! And I know that's for any car. Sure there are techniques but still.
I'm NOT bashing you or putting you down, just curious how you deal with it. Mileage is important to me as well but I'm not as cautious as you are.

If you pay attention to the world around you there is never a need for anything like that.

No, I don't know what you mean. hehe In more than 20 years of driving on 4 continents I have never experienced that. It comes back to paying attention to the world around you and planning ahead.
Even if your going on the on-ramp for the highway you have to accelerate even faster than gradual sometimes for "safety" of you and others so they don't rear-end you or have to slow way down and almost rear end you.
Ummm... no. :smile: As long as I am doing the speed limit, or close to it, by the time we reach the merge point we're all perfectly OK. If someone behind me is unhappy about that they'll just have to get over it. If they rear-end me they are automatically at fault in my State, and I get some free work done on the Yaris. I am not here to help other people waste fuel and create extra emissions by aiding them in their aggressive driving.
Also, how do you deal with rush hour driving like that and impatient people? Tailgaters?
For me rush hour is no different than any other time of day as we're all still on the same roads going the same places... there's just more of us. Impatient people are not my problem as their impatience will only get them home 3 seconds faster, and their impatience is one of the pure indicators of everything that's gone wrong with drivers today.
Tailgaters are usually not a problem for me as I live in the right-hand lane but they sure are an odd breed as they do things that make no sense at all. They tailgate me even in the right lane whether I'm doing 10 over the limit, the limit, or 10 under the limit. As such I've learned to just ignore them for the most part, but if I get one on me that's really aggressive about it I simply take my foot off the throttle and gradually slow down to about half the speed limit. That gets them to change lanes every time.
I also get the occasional tailgater on Mount Rose which is a very dangerous and intensive 2-lane highway, meaning only 1 lane in each direction. The speed limit on the mountain is 50 MPH and that's exactly what I do both up it and down it. Some folks like to think of this highway as a race track and are most unhappy with doing the speed limit but that's a problem between them and the Nevada Department of Transportation as far as I'm concerned. As such I never take it personal and I never pull out in the "slow vehicle turnouts" because I'm not going slow... I'm going the speed limit.
It's a different way of looking at and interacting with the world. Much safer, much saner, much more efficient and much more logical.
Just in case you're wondering, yes, I do get flipped off about once per month, and it's always by someone who is driving so aggressively that if a Police Officer were present they would go right past a citation to getting arrested and having their vehicle impounded.
I also get the occasional glare, but we all get that. hehe Window tint helps a bit with the evil eye types.
What's funny is once you become this attentive you begin to realize just how bad most other people actually drive. There's not a week that goes by where I don't see something that makes me drop my jaw and gasp in astonishment at the sheer stupidity and poor decision making. It would be funny if these people weren't putting us all in danger every time they get on the road.

BailOut, THanks for the explainations! With the acceleration on the ramp, I too just gradually accelerate as there is no need to floor it. But that's because there is little to no traffic but when traffic is a little heavier I have to accelerate to merge or even if I'm getting off one highway to the next (think clover leaf). Especially if a big truck is barreling down and since I have to slow down going around a curve let alone the clover leaf I have to floor it to get back up to speed when I get to the highway that was under the one I got off on, so I don't get crushed. So do you experience that? I totally agree with you in observing the driving, even I do it too (observe) and sometimes appauled at what some people do. In fact not long ago when I drove up to the north western part of Minnesota the speed limit out of the city was 70 but I went 65...until my mom (which I was following) was going 80 if not more cause we were late for something which sucked not only my gas and money but just you know...hurt. Then on the way back I was so uncomfterable with my sister driving as she is not MPG conscience like I am so I was upright and concerned the whole time. I should have took over but...I don't know! But knock on wood according to my scanguage I got 47mpg which I've done better and could have done better that time but oh well!
Oh even if you are taking it easy sort to say, in rush hour there are some moments you have to slam on your brakes, tell me you come accross that, well even generally just for safety reasons. I know you are aware but you can only do so much...and plus people might cut in front of you and what not or the light will change and you realize you don't have time so you put the breakes on or the person in front of you puts the breaks on. And I know braking hard kills mileage so...but thanks for the explainations. I'll take what you said in consideration.:thumbsup:

I experience the scenario you're talking about but it looks much different to me. If I'm going the speed limit, or at least close it, I don't care if there's a big truck bearing down. If he's speeding that's his problem, not mine, and with my blinker on well in advance I merge. If it's a scenario where he's doing the speed limit or less and we're going to be in the same place at the same time I just drop back and let him pass before I merge. At no point in any of that does my throttle pedal get depressed any more than the speed limit, or a reasonably lower speed, requires.

Again, this is where situational awareness comes in. No, I can't remember the last time I had to stand on my brakes in heavy traffic because I use the DWB (Driving Without Brakes) technique to avoid the jackrabbiting, and it requires constantly readjusting your forward speed to kind of pre-react to events that are unfolding up ahead before they become a problem. Yes, people often jump in front of me but I always have enough of a gap to absorb this without a problem.
I did have to stand on my brakes once last Winter, though, on Mount Rose. A tourist in an inappropriate vehicle (read that as a RWD rental SUV) lost control around a sharp and icy corner as they came downhill, and they were careening off the inside snowbank and outer guardrail like a pinball. They were completely out of control and their movement was so erratic that it was impossible to judge what the safest thing to do was so I just moved as far right against the snowbank as I could and then stopped as quickly as possible in order to eliminate my kinetic input in case we would collide. Luckily they missed me by a good margin and I was able to continue on my way unscathed.
Even then, though, because I was paying attention I had more time than I needed in order to come to a decision and implement it. I was in position and stopped from 35 MPH and just watching this fellow for a good 4 seconds before he passed me.
The same held true when my driver's door got hit this Summer. I didn't have enough time or space to fully get out of that guy's way after he failed to give me the right of way so I made a calculation and stopped where I thought he would only hit my door rather than scraping down the entire side of the car. It worked. My door got creamed but the damage was isolated only to the door. I saw him so early on that I had more than a full second to just sit there and simply watch him coming to hit me. heh

and so many of these dangerous situations could be avoided if the politicians would re-implement photo radar and speed limit the transport trucks to 90.

I usually do what you do and gradually slow down more if a transport is bearing down on me. Once I've decided someone is tailgaiting me to such an extreme as to endanger my safety, I figure the only way to cancel out their stupidity is to increase the space in between me and the car in front of me to enough space for both of us to stop. This results in various gestures and horn blowing, but that's their problem. On the 401 it doesn't matter if you're going 100 or 150 you will get tailgated and I'm not exaggerating one bit.
The merging part is a lot harder in the GTA, because of the huge volume, but I find the best way to merge is to put my signal on a while before the solid line turns dashed and gradually start hedging towards the left side of the lane. Usually people will slow down or get out of the merging lane, because most people here are going to merge whether there is space or not and usually without signalling. Signalling seems to be a lost art around here. You can never signal too early or too much.
I think the whole key is to become confident in your ability to control traffic as much as possible. For example, one trick I use to feel less pressure from bad drivers about going a reasonable speed is to find a transport truck going 90-100km/h and follow them but stay well back to avoid rocks etc. I find people will usually not cut you off if they have to change lanes in a few seconds again to pass a transport, plus I'm also supplying merging drivers with a huge corridor where they see they can safely accelerate into.

I think BailOut runs a manual tranny, but with my auto liftback, increasing speed gradually, or shall I say too slowly will actually decrease MPG...there is a sweet spot...too fast is bad, too slow bad for MPG too.
As to getting on the freeways, I treat it like a game. The objective is to get onto the freeway in such a way as not to force the dude coming on behind you to slow or speed up. If the dude bearing down on you is going over the speed limit, sure he's breaking the law, but will you still think that if you're laying in a hospital bed? I think we need to be pragmatic here. Safety trumps the law every time.
When the dude is bearing down too fast as I merge on, I will match or exceed his speed, then once on the freeway, I will gradually slow down to the posted speed limit, forcing him to do same....doing this while getting on is not often safe IMHO, and could turn this whole endeavor into a kind of contest of wills; something I don't want to get into.
In other words, there are a hell of a lot of dead people who've died in traffic accidents eventhough they were in their rights....the Californiam DMV driving manual states that one should never insist on their right of way, and I agree with this.

I do not know how many time I have seen trucks purposly run slow pokes off the road in ATL traffic... if you are not going 70-80mph (speed limit is 45-65mph), you are getting ran off the road by a semi, or a beatup hooptie that just don't care

http://www.forbesautos.com/advice/toptens/least-expensive-to-own-all-2007.html?
Click the slideshow in the article. The Yaris is ranked number one mainly because of its lowest five-year ownership cost.
I guess that the Yaris' low fuel consumption rate has contributed significantly to such a low cost. Its lower fuel demand is mentioned in the article.

In my experience, the slowest you can drive on the 400 series highways and stay out of fairly constant danger is 100 km/h or the speed of the transport in front of you.
I stick to the right lane and manage 100 for my entire commute from Markham to Mississauga road which is 50 kms on the 401. Sometimes there is a lot of pressure by tailgaters, but that just makes me slow down more until they pass.
Bailout talks about maintaining speed limit and that's what I'm able to do on the 400 series highways as well, but it isn't easy or perfectly safe to do so. I do believe it's safer to drive slower on these highways versus faster though and I have tried both ways of commuting. I also get far few rock chips going slower :smile:
There's no way in hell you could go 80 on the 400 series highways without getting killed, but that's not what Bailout is doing, he's going speed limit for the small roads he drives on. His situation is a far cry from the sometimes 6 lane wide 401 etc and not really comparible on any level except for the fact that you can go and should go no more than speed limit on any road.

Okay, so with my latest tank, with 95% city driving, AC on, perhaps, 1/4 of the time, usually with 3 people in the car, I got 33.5 mpg. Better than I thought I'd get this time around; close enough to the 34 mpg promised that I'm more than pleased. How I long for the open road again though and the

I average about 39 mpg, but 90% of my driving consists of highway miles plus conservative driving. Now, if i drive like a speedracer going 90-100 mph with the AC blowing...then its more like 35 mpg. LOL. But no complaints here! My 96 celica only gave me 25 mpg...groan... Definitely much better off now!

More things I've noticed using the SGII and different driving styles and road conditions:
After coasting down the same hills in neutral hundreds of times over different weather conditions, I can state with confidence, that the temperature's effect on the rolling resistance of the tires significantly impacts fuel economy.
While it's common knowledge that cold weather is bad for FE, I've come to the conclusion its mostly due to: 1. Increased warm up time, especially when the temp is below freezing; proportion of warm-up time as part of trip time is larger. 2. Rolling resistance is the greatest of all temperature FE effects after the motor is fully warm.
Where to go from here:
Research tire rolling resistance?
I've never seen it listed as a parameter, but I suspect
1. High performance tires are "stickier", and therefore worse for FE.
2. Narrower tires and tires with a smaller contact surface (perhaps even snow tires) are better for FE.
3. Are southern/tropical region OEM tires different from temperate or arctic region OEM tires? If so, is it due to a need for different temperature ranges? If so, does this include rolling resistance performance? Do ratings standards organizations mandate that the OEM state which tires are going to be used in different markets/regions, etc?
4. Research optimum tire pressure for temperature & FE. Cruising with under inflated tires is definitely worse, but what is optimum? Cold air decreases air pressure and stiffens rubber, rolling resistance creates heat, heat increases air pressure, higher pressure decreases rolling resistance, etc
Possible mods - My first thought was to redirect the air intake to pull air from inside the cabin, but lowering the cabin pressure might create a carbon monoxide hazard. An alternative might be to cut a hole in the air intake duct between the inlet and the filter so it gets more air from behind the radiator & duct-tape the hole in Summer. I suspect this won't decrease the warm-up time by much (if at all) because hot water doesn't flow through the radiator till the motor is warm. Probably the best thing for cold weather FE would be a block heater to decrease warm up time...and perhaps narrower tires.
Scangauge Calibration
Speed & Miles driven - My SG registers about 1/6 of a percent longer distance traveled per tank than the ODO. Adjustment unnecessary.
Fill tank - correction adjustment ranges from -3% to -6%.
Fairly aggressive hypermiling, but without shutting the engine off while moving, coasting at idle instead of DFCO tends to make the SG say the FE is better than actual, and a -6% fill adjustment corrects it to within a percent.
Less aggressive hypermile, and increased use of DFCO, SG still says FE is better than actual, but less so, and -3% fill adjustment corrects it to within a percent. This is my usual mode.
Driving aggressively in commuter traffic, idling at stops, hundred mile trips in the rain, etc, and SG fill adjustment will want to be around zero.
Last winter, the SG fill adjustment was consistently around -7 percent, and my FE was around 40-43 MPG depending on how cold it was. Since then the SG fill adjustment has drifted to around -3%. I don't know if the difference is because of temperature, motor break-in or both.
32560 Miles, 693 gallons, one year (4 seasons) average FE 46.98 MPG, 90% highway, manual sedan, no mods, Goodyear Eagle GT OEM tires, Rhode Island (sea level).

47 MPG , 5 l/100km wait is this for the d-4d engine.. isnt that just about 86 hp on it..
I think Bredayaris has a diesel engine. Diesel engines are known for their good fuel economy. Although the d-4d engine may not have as many hp as our gas engines have, relatively speaking, it enjoys an abundance of low end torque which can compensate somewhat for its limited power.
I believe if Bredayaris tries harder, he can achieve an even better result.

I drive almost 100% city driving (under 50 mph) and when driving normally (accelerating moderately hard, but not stomping it), I get about 33 mpg. When I barely touch the pedal, shift at about 2300, then I get about 44. My record on gas is 47 mpg, awesome for even a hybrid!
Also, to figure out your rpms at a certain speed (for those like me without a tach), I went to vehix.com and found the gear ratios for my manual transmission (the autobox ratios are also there I believe), and then plug them into a gear ratio/tire size/rpm speed calculator. At 40 mph in 5th, the engine is at 1800, at 60, it's at 2800, and at 80, it's at a lofty 3600. But on a trip to Canada once, crusing steadily at 82 on flat terrain, I still averaged 37 mpg!

@ swng
My Yaris D-4d has 90 hp and 140 lb-ft instead of 106 hp and 103 lb-ft.
0-60 mph isn't that good as for the 1.5l gasoline engine, the diesel does that in 10.7 sec, but the high torque is really impressive. It pushes you in your seats.
I think i can easily get a better mileage, but remember the Netherlands is one of the most populated countries in the world, everybody is in a rush.
Our maximum speed at the highway is 75 mph, in the US slower correct me if i'm wrong.
My colleague has driven for over 30 years in the US and he says it's a really slow way of driving instead of in Europe, not even talked about the Netherlands ;)
But if i drive 62 mph i can get easily 52 mpg or better.
Thanks Bredayaris for the additional information. Your fuel economical and yet fun to drive diesel Yaris is a very enviable car. Hope you enjoy your visits to this thread.

I think you're revving too high. I keep my shifts under 2000rpm, but it revs at 2500 when I'm going 100 km/h and I very rarely go over 100 km/h over about 60 mph. I do mostly highway driving but even when doing plenty of city driving and am averaging 44 mpg. Try accelerating slower and not going over the speed limit and I'd bet you get over 40mpg in the summer.

As for driving the speed limit, it says 50mph, most people during the day do 60-65, and at night up to 70. So you see its hard for me just to even do 60mph at times. But even so, I tried my best and only got 32mpg. Mind you this is also after taking out two 12" sub's and changing back to stock rims/tires. I guess Im just unlucky with my car?

I know what you mean, it's not easy to drive in a way to get good FE when it seems like everyone around you is way too hard on the gas/brakes and constantly speeding, but I no longer care about these people. If you get into an accident or get a ticket because the guy behind you is pressuring you to go faster, they don't care and no matter how fast you go someone is going to be pissed off at you for not going fast enough!
You're still getting good FE, but you would do better if you didn't drive faster than speed limit and accelerated slower.

the most i can get on the 1st bar is 126km. i fill up on 570 with 38.5 liters.. with 3.5- 4 liters left over..
At the earlier days of my Yaris, I sometimes filled the tank until it spilled and I have for once exceeded 180 km with the first bar. I believe that some member(s) has/have done even better. Now I just fill till the nozzle automatically stops and I get more or less what marcus gets as described in his above post.
There are lots of road works on my way recently. My fuel economy is bound to be adversely affected. I am not too optimistic about the result of the current tank.

Hi, I am a new member to this forum. I found this thread very informative and resourceful. So, I thought I might as well share my fuel consumption numbers with all of you. Firstly, we have two Toyotas in our household, namely a 2007 Yaris LE (5dr)(auto) and a 2002 Corolla CE (auto). The average number for the Yaris is 6.54L/100km (15.3km/L). The average for the Corolla is 6.83L/100km(14.6km/L). The numbers represent purely highway driving (~95%) of 37km(one-way to work). I am a bit concerned considering that Yaris is a lighter car (1050kg) compared to the Corolla (1200kg). I usually drive at around 110-120km/h on highway 401. I will keep you updated with my future consumption numbers for the Yaris. Hope this was a useful piece of data.

I don't know what's up with my FE on the past couple tanks. I used to always get very close to or pass 500kms on the 5th bar but the last 2 tanks I barely clear 460 before that bar goes. I'm chalking it up to the colder weather, but it's been warm this week. I don't know what else could be causing this. I just passed 8000kms and am going to do the scheduled oil change tomorrow, but I did an early oil change and check over at 3500kms so I can't see it being something wrong with the car. Tire pressure is fine, nothing has changed. Anyone have any ideas what it could be?

You can't go by the bars, voodoo22. They are not linear nor static. The only measurement you can count on is at the pump (dividing your distance traveled by the amount of fuel you fill with).
Even then your best bet for measurement consistency will be to always fill up at the same time of day (i.e. on the way to work in the morning), at the same station and at the same pump.

Thanks BailOut. I do fill in at the same station and same pump at about the same time every fill so that should help, but lately I'm using an extra .1 to .2 litres per kilometer.
I didn't realize that about the bars. I don't much care for them and would much prefer the return of a needle display. I was wondering why some of my better tanks of gas I would often start out with 120 kms or a little more on the first bar and 100kms or more on the subsequent bars, but lately on the bad tanks of gas I'm getting 135-140 on the first bar and then not even 100kms on the bars after that.

I get the same thing.
This tank si strange cause I did not follow the rules of accelorating slow and not driving at the speed limit, but somehow, the half-way point on the indicated didnt lose that bar until 242miles!!!! Which is a record for me!!
But watch it start blinking when I hit 310miles or so :( I dont get how I lose 3 bars in 60-70miles, but lose the first four after 200-240miles.

As you described it, it is strange. IMHO, under normal conditions, it is unlikely that three gauge bars can be lost in a matter of just 60-70 miles considering that the same car has covered 240+ miles for the first half of its fuel gauge range i.e. half the number of the bars (NB:not the car's real range). It is my presumption that all relevant conditions have remained more or less unchanged. Otherwise, anything can happen, right? Yet on the other hand, it is not too unreasonable for the last bar to start blinking at 310 miles (about 500 km). All gauge bars are understandably not equal when it comes to the distances that they individually cover but your case appears a bit too weird.
The car should presumably be under warranty and I would suggest taking it to the dealership for a checking.
All the best!

I did that one when my last bar started blinking at 240miles or so for a few tanks. They said it was bad gas, and even took a cup of it out and showed it to me in the room with everyone and they said it smelled bad. Lets just say I never went nor want to go to a BP station ever again. But they told me that they would not do the work to check the fuel tank/filter, and that the ECU didnt show anything wrong, and this was even after I insisted. Whatever maybe I was pushing it but I dont like how I drive like a grandma most of the time, and all I get on average is 3mpg more. :( I could race the car all I want and drive at 90mph all the time and I would always average atleast 26-29mpg. I drive slow, and now its just 32. Lets see tomorrow when I fill her up.
And that was also the tank after pushing the car to the gas station cause I ran out of fuel!! Stupid me forgot to put gas i the car and ignored the miles that day. Ran out completely at like 336miles or something which isnt that good either.
Anyway, its at 310miles right now and still got a bit more I suppose before it starts to blink!
Maybe it is the crappy air filters they are putting in the car?
I mean I got the pil changed to synthetic and changed the tranny fluid and it didnt really do anything, but the car felt a bit stronger.
Thanks Lafiro for the additional information above and the friendly communication as a whole. I think you have done a lot of things conscientiously trying to bring about some improvement. Let's hope that it is just the gas that has caused you the relatively low F.E., as the dealership seems to have claimed. Frankly 26-32 mpg (US) is not too good but also not extremely bad. IMHO, improvements are not impossible.

I've got my 50 mpg today, but i can do it much better.
My boardcomputer said that i can drive 434 miles with one tank of diesel, but my boardcomputer is very negative. And it's better to have 1/4 filled up of your fuel tank.
In the Netherlands it's called : ''het nieuwe rijden'', the new driving.
You have to drive in 4th gear if you go 31 mph, but if i do that my dieselengine doesn't like that. It revs less than 1800 rpm at 31 mph.
43 mph in 5th isn't good for my engine too i think.

I will follow this. Would it also make a difference that I have two nice amps still connected to the battery? I would assume all extra demand on the alternator would then mean less miles per gallon? Specifically since I removed the two sub's the 2600watt amp is still connected. The 4 speakers then are connected to a 1200watt 4channel amp which is always on and I always listen to music. Maybe this is affecting it as well? But I cant assume this will affect it any at all?????

Okay, so I had my first instance of premature bar droppage; I usually get about 46 miles per bar, not including the first one which varies from 68-75 miles, and the second one which sometimes gets me 50+ miles, so when my bar dropped 20 miles short of this, I was disappointed. It happened while idling in a bank teller line; I would normally have turned my engine off, but there was only one car ahead of me and it looked like she was done. So as I'm waiting, whoosh, the bar drops, and I grumble. Once it's my turn, I pull up and turn the car off. After my business, I turn the car back on, but the bar is still down. I head off down the road, I'm coasting down a hill and "pop" the bar comes back :) So, how often has this happened to any of you, and why does it happen? Any thoughts?

hey marcus, i also noticed an improvement in fuel economy when using a tank of premium gas.
i made the same 600 km round trip on two weekends, one with premium gas and one with regular.

Perhaps it's because my driving style is so different.

BailOut
09-28-2007, 05:56 PM
I've done that. 89 Octane = a loss of 5% MPG, 93 Octane = a 9% loss.
I tried 2 tanks in a row of each to get a more accurate test (and the low numbers hurt my running tank average). Without a doubt I consistently get the highest MPG with 87 Octane.
Aside from my much calmer driving style two other things that may make a difference for me are that we're always on 10% Ethanol here and I'm at a higher altitude than most folks (my home is at 4,500ft., my office is a 6,350ft., and I traverse an 8,900ft. summit to get there).

The EPA changed the way they do the test to reflect the way people are actually driving rather than how they are supposed to be driving, starting with the 2008 model year.

Once again thanks for the communication and your interest in the subject of this thread.
I am no expert but I know that amplifiers do not run with 100% efficiency. Some amps (for that matter, sound systems) can have a higher efficiency then the others. When an amp is switched on, a certain power, which has to come from the gas you buy, is lost i.e. not producing sound. Say if the amps' average efficiency is x %. Then each time an amp is on, (100 - x)% of power is simply lost. At the same overall sound level (deep bass requires a lot of power anyway), the greater is the amp's list power, the more power, hence your fuel, is likely lost. A distant analogy is that at the same speed and carrying the same driver, an SUV uses more fuel than our Yari:wink:. Most amps consume a certain power whenever turned on, whether the volume is turned up or music is played at all or not. A visible circumstantial evidence of the power lost I am talking about can be found in the big heat sinks (the multiple heat dissipation fins) that are built into the high power amplifiers. Apart from whether they are electrically safe to touch, those things are very warm or even hot to touch after the amplifiers have been switched on for some time. Even when we are not talking about amplifier efficiency, generally, using the sound system consumes power. Again, some systems are more efficient than the others, but no sound system can run without using power. As a rule of thumb, heavy bass consumes the most power.
I submit that for comfort (e.g. masking the noise), pleasure, safety and convenience (i.e. traffic and weather reports etc) and alertness (that is keeping you from falling asleep whilst driving), there are certain advantages of turning on the sound system, so the fuel is not consumed for nothing. However, bigger sound systems usually mean bigger fuel bills.
Just a further note about http://www.howtoadvice.com/SavingGas, there are some links to a few very useful articles at the bottom of the page. If you have time, I recommend that you go through them, at least cursorily. As a disclaimer, I wish to point out that some gas saving tips may contradict with some others and they are to be adopted (or otherwise) with good sense, with reference to the local laws and driving environment, and at one's own risk.
Just my humble opinions. Correct me if I am wrong. Please post here often:smile:.

Do you use Shell gas? Shell puts no ethanol in their premium, but up to 10% in their 87 octane, so you should see an increase in mileage with Shell premium even if there is no performance difference for our cars when going with a higher octane.
I can't stand this 10% ethanol crap. Keep the corn for popping.

Do you have Shell gas around there which put 0% ethanol in their V-power? I wonder how that would result. I can't see you gaining over 9% based on no ethanol. I only use regular and can't justify spening over 10% more for gas when the car doesn't need it. After years of buying premium, spending less than $30 on gas at the end of the week is something I don't want to give up:thumbup:

I only use Shell gas and E10 is a mandate. Regardless of the Octane level, if you buy it in Nevada or California it's 10% Ethanol. In the cold months it gets worse as our Winter fuel - by mandate - is E10 RFG (reformulated gasoline).
This helps the lead-footers produce much less emissions, which is a good thing, but by proxy it robs the proper drivers of lots of mileage.

I have auto/sedan. My city driving is in a town of 20,000 people, so a lot of stop and go driving. Stop signs every quarter mile or so. No merges or blending traffic like in a larger metro. It's also colder which means it's idled longer than normal. But still, 23 mpg is disappointing. It is under 3000 mile and I'm hoping for improvement upon break in. I do not mash it ever I coast as much as possible but I do keep up to the speed limit. Some people tell me their Corolla is getting better mileage. :frown: Or their lying.

I doubt the gauge is this precise or this linear. At least I've never come across one that was.
There's one reasonably accurate way to measure fuel economy. Fill the tank. Drive. Fill the tank again (hopefully to the same point each time--two clicks with a few seconds in between is what I do). Divide miles driven by gallons used.
Some people might think this method is just common sense. But I've come across many people who estimate MPG based on the fuel gauge. Usually a bad idea.

Sounds like 2 major things you could focus on is getting off the gas when approaching stops and your car is above idling rpm (around 1300 rpm and up from what I've read.) to benefit from DFCO and I cannot stress enough how you cannot go too lightly on the throttle from a dead stop. Initial acceleration cannot be too slow in those situations. Bailout talks about hang time when you are already moving, and that's another example how a sensative touch on the throttle can result in large savings in gas. That doesn't mean you should accelerate slowly when at hwy speeds (once you get going it's more efficient to accelerate at a much faster rate then when you are starting from a dead stop), but learn how to give the car the least amount of throttle to achieve your necessary speed.

lol.. can you tell when i put on my rims/tires and took off the stock ones?
i've also started getting more relaxed driving a little faster... i guess i'll have to get back on the ball.
this is with no engine mods, 205/40/17 tires on enkei rims, custom woofer box in the back that probably weights 20-30 lbs
Whoa... With gas at $3 those wheels are costing you $200 per year, and driving faster is costing you another $200 per year.

yeah I plan on starting to hypermile more again and keep it under 55 on the hwy
35 seems to be about the best i can get with the wheels .. but they make the car look so sporty.. lol i'm not going to get rid of them
with the money i'm saving since i got rid of my jeep 16-18mpg that $200 a year is nothing lol

..and if you haven't taken the new tire size into account in your calculations, you can add another 1+% to your figures, because that's about how much further the odometer will read over actual with that new setup if you went from 15's. If you went from the stock 14's then you can double that difference to 2+%. It's not a lot, but it adds up by the end of the year.

it just dawned on me..
when the mpg started going south was when the weather started getting colder.. and i had to run the Defroster for the front windshield alot.. from what i was reading earlier the defroster runs the AC too... thats probably more likely the cause.. whenever i have the heat on its always on the defrost/footwell setting...

I've come across many people who estimate MPG based on the fuel gauge. Usually a bad idea.
LOL! Thats too funny!

In my 2009 owner's manual, page 178 states that:
"If A/C is not pressed, the system will blow ambient temperature air or
heated air."
And then later on page 183, it states:
"When the outside air temperature approaches 32 F (0 C)
The air conditioning system may not operate even when A/C is pressed."
Perhaps that has changed from the 2007 or 2008 model year, as my buddy
who has a 2007 said that he thought the A/C came on automatically when
he moved the selector to the feet and windshield defroster setting.
Is that a definitive answer or not. :iono:
I have heard that other makes of cars use the A/C when in defrost, but who knows?
40 m.p.g. . Trip was many steep hills , 20 m.p.h. winds , 28 > 30 degrees , 2 people , 30% city 70% highway , 1/3 tank of SUNOCO 87 octane along with 2/3s 93 octane containing 10% ethanol , and GOODYEAR Eagle LS tires set at 34 p.s.i.. Using SHELL Full Synthetic 5w-30 and REDLINE MT-90 true synthetic for gear oil . Quite good for these temps and the winterblend of gas . :thumbsup:
very poor gas consumption: 22MPG or 400 KM off 42 L
My car: 2008 Yaris Hatchback Auto. total mileage is 10800KM.
I have some strange issue. Everytime when I start the engine and give the gas, the car engine will be revving but the speed stays slow, this may last around 5 mins and when I loose the gas a bit, the rpm will drop sharply and I feel a sudden push somehow. I always drive around city limits and mainly do the city driving. Any recommendations for that?
It kinda drives me insane as the main reason I go for yaris is for the gas consumption but it did not give what I expect.

That is odd indeed, hshi. It sounds as though your air and/or fuel flow is restricted, either by physical blockage or by the ECU. Since your vehicle is still within the warranty period I encourage you to take it to a dealership for repair. If you are more the DIY type here are a few things to try:
1) Check the air filter and reseat/replace it if necessary.
2) In the fuse box in the engine compartment pull the ECU fuse for 15 minutes and then put it back in.
3) Get a fuel injector cleaning gasoline additive and use it.

Hui,
Do you have a very short commute? Your symptoms sound like the engine warm-up cycle is affecting your shifting. My wife's auto XB retards the shifting while the engine is in the initial warm-up phase. Get out for a highway drive on the weekend for a good 20 minutes or more to make sure the engine gets to full temperature for a good while. If that tank significantly improves your average, consider a higher temp thermostat, engine heater, different oil, or other tricks to warm it up faster.
In Canada you should have gotten the cold weather package Yaris. The dealers shouldn't have had any others. If your not sure, have a mechanic check and evaluate if you are having cold engine problems.

Less than 3000 miles on the care and last tank was 44.8. In town and rural roads. Some 2 lane highway driving mostly 70 degree weather. I can hardly wait for highway driving in the summer!

I am surprised so many people are reporting such low fuel economy with the Yaris.
I have a 2009, 3 door, well broken in now with 31K on it. On the freeway (74 MPH with A/C on) I typically get in the low 40's... 42 is very common.
In town with hypermileing techniques I have gotten as high as 51, but more typically get around 48 or 49 MPG.
These are the same kinds of numbers we got in our Prius (which my ex-wfe now has). I used to love the Prius, but now... considering the embedded energy in that vehicle, it seems silly to buy one when with conscious driving (what the Prius tries to do for you) you can obtain similar fuel economy. Plus the Yaris was $11.5K & the Prius was over $30K.

I think everybody who speeds above the speed limit on the highway should stop on the shoulder and look out their window. When I'm going 65 mph on the freeway, I feel like I'm moving in slow motion, but it's scary how fast 65 mph looks when you're completely stopped.

2008 automatic sedan : 44.56 for calculated mileage . ECO-METER : 44.2 . E.M.. Set at 98 . When set at 99 it's too high . No in betweens .

Using hypermiling techniques, I'm typically getting 48-50 MPG too! My highest so far was 53 MPG. The car is a 2010 with about 5,600 miles.
I'm actually doing about the same average as a Prius... at half the showroom price. That is why it was important for me in purchasing the Yaris. You can squeeze out comparable MPG with pretty much the same 'footprint' as the Prius! Go figure!
It would be nice if all people across the board purchased small vehicles and drove thinking common sense, efficiency, and used hypermiling techniques. Then we would really be 'green' even without having to drive marketed 'hybrid' cars!
Cheers! :smile:

here's our latest mileage when we went to look at a 2011 Fiesta . The 1st pic is M.P.G. average ( 45.3 ) when we arrived at the dealer lot . The second pic is the overall average ( 43.4 ) and miles when got home . The E.M. is set at 98 so reads slightly lower than the calculated fill , when at 99 reads too high . So likely at 44 avg.. Not so bad for a automatic . Still found a slight leak of the head gasket . Tip of finger was wet with fresh oil after cleaning it before the trip . Seems to be slowing down .

If you use the same hypermiling techniques plus the special ones for the Prius e.g. super highway mode which lets you get 70+ MPG on the highway http://www.cleanmpg.com/forums/showthread.php?p=171831#post171831 the Prius would have a much higher MPG than the average driver. :biggrin:

That's certainly true, but then you'd have spent at least twice as much for the Prius which takes an awful long time to break even on, and there are batteries to contend with.
Don't get me wrong - I have no problem with batteries and would absolutely love to have an electric car. I just don't care for the hybrid concept, or the tiny battery that the Prius uses which mandates a lot of load on it.

I've purchased all my cars used. I've seen a used Prius at Enterprise for around 16-17k. My used Yaris was 10,600. I commute 130 miles a day but I don't plan on having this commute forever. I would probably break even sooner than the average person but you can't go wrong with either car.
There are reports of the original batteries on Ford Escape hybrids running past 300,000 miles. http://www.greencarreports.com/blog/1020431_more-proof-that-batteries-last-ford-escape-hybrid-taxis-retire-with-300000-plus-miles A Prius taxi driver in Canada was still running past 200,000 miles. I don't have any doubts about maintenace or longevity on the batteries.

You can always find the exception to the norm. All it takes is one time and you are stuck with a fortune in battery replacement costs. A Yaris battery is cheap..and the cost benefit of a Yaris over a Prius or any other hybrid is a no brainer.

It's unfortunate when it happens even to the most reliable brands out there. A battery replacement at Art's Automotive would be around $2850 (including labor) if the battery packs remain at $2500. http://www.artsautomotive.com/hybrid-articles/38-hybrids/140-predictive-battery-failure-analysis-for-the-prius-hybrid
Battery replacement on 1st gen Prius: http://www.artsautomotive.com/hybrid-articles/145-installing-a-prius-hv-battery
Art's Automotive from a mechanic's standpoint does point out that overall the maintenance cost and gas savings on a hybrid will cost you more than purchasing a high MPG commuter car like the Prius or "new" Fiesta.
I'm still trying to break the 40 MPG barrier and I have an Ecometer on the way. I'm going to try testing it with A/C on/off, fresh air vs circulating with with A/C off, etc to see what the MPG impact is.

I only get 37.3 mpg with AT. Wondering if I could get better? I do 60% hwy, 40% city, live in suburb Garden Grove, CA. I accelerate really slowly, time red lights and limit brake lights, limit idling, go 5 mph below speed limit in city, go 65 mph on freeway, no AC usage. Have 0w20 syn motor oil. How do you guys get above 40 mpg or even 50? I believe I drive slower than 100% of the people in my area.

tires pumped up to 45? i think this is the best single thing to improve mpg on any vehicle.

we achieve 40+ for both automatics with 35 > 36 P.S.I.. Just filled the sedan earlier and got 41.35 miles per gallon .
Since I have owned my Yaris, including all the gas I've put in, my overall mpg is currently over 41. I just drive it. I shut off at long lights, it has been over 90mph, just auto crossed it last weekend. It has been to the fuel cut off. I get stuck in stop & go traffic. 42 psi frt, 35 rear. Synthetic oil, some stuff stripped out. 45mpg one time high on a tank full. Put 14" BBS wheels w/ 185/60-14 and it runs even better. I put photos on the forum.
