Fuel Economy

[swng]

theladybug,

you will probably see some improvements in fuel economy once your engine breaks-in a little more,
but with the type of driving you are doing, i wouldn't expect to see great numbers........

Well said friend. There is one more factor which may not be friendly to her fuel economy, i.e. the arrival of winter:frown:.

[Yaris]

I'm not too thrilled with my fuel economy. Granted, I'm only a quarter of the way through my third tank, and didn't count the first one that the dealer put in, but still. I thought it would be better.

Like it or not, your car is consuming winter blend gas and you will not see improved mileage numbers until next spring when the winter blend gas will stop being served until next autumn.

If you have ethanol in your gas, you will most likely be griping about your mileage all winter. :mad:

too true swng, my car was new last winter (so not broken in) and I was only getting about 27 mpg.
do you get the winter blend fuel in bc? i suppose they might need it in the interior, but you wouldn't think it would be necessary in vancouver or victoria,
are you on the coast?

[theladybug]

but with the type of driving you are doing, i wouldn't expect to see great numbers,

That I know is true. I'm looking forward to taking my Yaris on its first road trip, actually, so I can see what kind of fuel economy its actually capable of.

Yes, I live close to the delta of the Fraser River where it flows into the Pacific Ocean. The weather forecast for my city today is 7(highest)/2(lowest) degrees C.
I guess in winter, the whole country is served with the winter blend, but please correct me if I am wrong. I really am not sure. If I have a chance, I will ask the professionals about that.
Regards.

I hate winter! I see my mileage going down as well, okay its decent but nothing like it was in the spring and summer. I'm getting low to mid thirties but oh well. I guess if I try I probably could get 40's but I would have to try harder in the winter time and as mentioned before the winter blend stuff in the gas at gas stations don't help:thumbdown: :thumbdown: :cry:

[swng]

Yes friends, winter hurts our fuel economy in a number of ways, several of which have already been pointed out by some of you above. It is "comforting" (forgive the not too appropriate choice of word), however, to understand that many other cars are probably more hurt than our Yari.
Anyway, to help form an impression about how big the damage is, please keep on updating your numbers here throughout this winter.
Within safety limits, let us try our best to achieve good results despite everything.

[Pars]

Seem like the cold weather and winter gas is going to take about a 4mpg hit on the Yaris. Probably more if you have more then a few cold starts per day and are driving short distances.

[swng]

Yes! Also, IMHO, tires become stiffer in the cold, producing more rolling resistance. Snow tires may be better but only to a certain degree, and most of them inherently have greater rolling resistance than summer tires. The engine takes longer to reach the ideal working temperature, and in many a case, it has to work against oil that has been thickened by the cold, at least initially before the car warms up fully (synthetic oil may have an advantage in this respect).
Besides, people tend to eat more, wear more, and carry more stuff in winter (it is prudent to have a blanket to keep warm, some first aid stuff, a few coins for emergency phone calls, a chocolate bar and other things, e.g. a battery operated torch, in the car just in case we get stranded anywhere in the cold weather far away from home). All these make the load heavier. I have been told but forgotten the source that a mere addition of 5 lbs can produce a noticeable difference in the fuel economy numbers in the long run.
Limited visibility and poorer road conditions may also prevent us from driving at the optimum speed(s) for fuel economy. Reduced traction can render the using of some fuel saving driving skills inappropriate. For example, in summer, we can let the car cruise down a slope at the highest possible speed as far as it is safe and then use the momentum to make the car move on for a while after the slope ends. In winter, the roads are more slippery and our downhill speeds must be reduced for safety and hence less momentum can be gathered for later use.
These are but a few factors which affect our mpg numbers adversely in winter. I can think of more and I am sure many of us know a lot more such factors, technical or otherwise.:smile:.

[BMGYaris]

well my first take was 29 mpg, but i drove really really fast on the interstate so no surprise. Then i took it in to get the alignment fixed the same time i filled up. My second tank has just yieleded 23 mpg all interstate never over 80, mostly abotu 70, tire pressure is checked oils and all checked, nothing really to explain it so its going in to the shop monday and they will run some test and all...lets hope they can fix him or they give me an awesome trade up:)

:laughabove::tongue: :laugh: :biggrin: :bellyroll::thumbup::clap:
Lovely! How humorous and how observant!
Actually more advices say a 100 lb difference in load can mean a 1 - 2% difference in the fuel consumption rate:smile:.
Please see:http://www.google.ca/search?q=fuel+saving+tips&ie=utf-8&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a

Incidentally, the advice below is from:http://www.tdc.ca/savinggas.htm

"Personally lose some weight. Yes, if you are overweight and need to lose A FEW POUNDS - do it and you will save gas because the weight in the car you are driving will be reduced. We know that there are a high percentage of people who live in North America who are definitely overweight... what a great incentive to lose A FEW POUNDS when you rationalize it by saying you can save a few dollars on fuel as you lose some of your personal weight"

I have capitalized a few words. Please go to the middle of the linked page to see the paragraph in its original form.

Good health to your wife and you:smile:!

[eTiMaGo]

It's quite true, on a lightweight car the weight of the occupants can be a large percentage of the total weight, and reducing this total weight should include a good diet :biggrin:

[BMGYaris]

PLEASE READ:

I posted a few post up. I havent gained any weight and my fuel is of the same quality (dont think we get much winter mixture down here in south carolina) but i have an update on my problems.

Just last night i was driving, engine still cool, no problems though. i turn at a redlight, get giong about 25, tap the gas and suddenly there is a loud high pitched..whirrrrrrrr and

i was hardly accelerating at all. i let go of the gass...i turn of my music, tap it, whirrrrrrrrrrr,

i quickly feel the automatic clutch, its in drive, i pop on the light to confirm, not in neutral, not in third, in drive, i check the parking break, its fine, i tap the gas, whirrrrr

i start to pull over and tap it one more time and its smooth as butter, regular deep voice of automatic transmissions shifting gears. no problems the rest of the night.

I suppose what ever has caused my drastic decrease in mpg all the way down to 25 all highway driving at average 65mph is also causing this problem. Anybody have any ideas what is wrong before i head of to the shop on monday let me know.

I really couldn't tell you, the "whirrr" I assume is from the engine not the tranny? :iono: Since you said the car is still cool, it doesn't shift into the overdrive gear (4th) but once the engine warms up or gets to "normal" opperating temps it shift, that's if you have an automactic but otherwise I don't know, I'm just guessing. Hope its nothing too serious.

[sanchez]

my yaris with the way i drive( undernormal conditions) can get me at least 370 miles on a full tank

[swng]

370 miles = 590+ km. Not bad :smile:!

[palsan]

The owner's manual suggests filling up when the tank is down to about one quarter. When I got the car a month ago and I read that I thought :thumbdown: - visits to the gas station more than once a week, that sucks :eyebulge:

HOWEVER ... I do about 450kms a week and three quarters of a tank are plenty for that!

Filled up yesterday for the first time since installing winter tires: 497.3Km, 34.78L or 6.99L/100:thumbup: :clap: :headbang:

I can keep filling up on Tuesday or Thursday nights (the cheapest times to buy gas in Toronto) every week and still keep more than a quarter tank :drinking:

:evil: dont get too excited:evil: , as some other have commented, the top seems take longer to run down, maybe due to the shape of the gas tanke, maybe something else i dont know, but that 35 is probably looking around 30-32...could be less. Dont pretend you have any idea until your down to the last 2 man:) even then its very iffy till you fill up. i hope it goes well though

I mean think about it, if your tank is 11.1 gallons, and you have 8 bars, then each one theoretically is 1.39 gallons per bar. Which is what you used and got with 48/1.39=34.5mpg However, if the bar didnt drop until 1.5 then it is 32, and if it didnt change until 1.6 then it is 30mpg. so for ever .21 gallons the reader is off on the first bar then you are geting - 4.5 mpg. What kind of margine of error you think it has? id say def larger than 0.21 on the first bar

True, if what youre saying is true it will make me a sad panda. Will have to wait for the whole tank and see. Thanks for the info :D

About the margin of error im not sure, however I made sure not to take into account the first bar. I think my estimate came from the 3rd bar.

The thing is that if you fill up the whole tank you cant control the amount for the first bar, so best thing i guess is start counting from the second bar until the 7th vanishes. Ill try that

May be you do not have to ignore the first bar if you use the calculation methods described in this web page:

https://www.fueleconomy.gov/mpg/MPG.do?action=calcMPG

Please note, however, that variations may exist between different fill-ups. Take a long term average to minimize errors and deviations caused by various factors.

[BMGYaris]

so best thing i guess is start counting from the second bar until the 7th vanishes. Ill try that


I never meant to ignore the first bar in your calculations. I just meant that the gas fuel guage is not precise, it is just rough estimates as to how much gas is still left in your tank. Thus no bar or number of bars represents exactly what it does mathematically (mathematically each bar equals 1.387 gallons, but in reality it will not drop at that precise moment). Suppose that on your first bar it was off .21 gallons off. that would be something about 15% more fuel consumed than what you mathematically yield should have been used on your first bar. But the more bars that are gone then the less the margin of error impacts your calculations.

So what this means is that on one bar the margin of error is going to represent some range of fuel consumption, lets say anything from 5-25% more than what you would expect that first bar to actually represent. However, as you use more gas, the actual margin of error (say .21 gallons) should remain pretty consistent (within a range). That means that if .21 gallons creates a 16% inaccuracy when guestimating from your first bar, you will find that the % inaccuracy decreases as your fuel consumption increases. Thus as the total gallons consumed increases the error will represent a smaller portion of your gas consumption. Meaning the more gas consumed the more accurate your bar guage will be, though no one particular bar will be any more accurate than any other. You should always calculate with all available information

Note: im only talking about rough guesstimating before fill ups. Obviously the only way to get true readings is to fill up many times at the same pump. I just didnt want him too be too shocked when his 35 mpg city turned in to 29 or 30...hopefully 32.

[regulus]

Thanks both for the info :D

Ill keep you posted

[swng]

You are welcome and good luck!
BMGYaris' advice makes lot of sense to me. I admire the meticulous calculations.
In my layman's language, all bars do not necessarily represent the same amout of fuel and hence mileage. Depending on how full the tank is filled up, the first bar usually represents anything from more to a lot more fuel than the others. Trying to estimate a car's fuel economy with the data collected from just one bar can lead to a rather unreliable result. The bigger is the database, the better.
Long term averaging and consistency in filling up location(s) and method (I would say) can help minimize the effects of many possible errors.
Good research friends:respekt:!

[keesue]

Very first tankful = 35.6 miles/gallon

[swng]

The result is quite good keesue, considering that it's your first tank and that winter has arrived (weather should not be severe in San Francisco right now though). I presume you are reporting in miles per US gallon. That will be more than 42.5 miles per Imperial gallon.
Please keep on posting your results from time to time and describe your driving style and the traffic and load conditions leading to your results every now and then if you don't mind.
Thanks!

[keesue]

I sure will. These miles are 85% commuting. I drive at an average of 65 miles/hour. I expect, as the engine breaks in, to get another mile/gallon. I'll keep you posted.

my last tank of gas i got 43.1MPG But this tank isn't going to be as good bad weather having to run my deforst a lot wish that had't linked it to the a/c

[palsan]

my last tank of gas i got 43.1MPG...

I'm assuming from your profile that you are in French Lick, Indiana, so I'm guessing your numbers are in US gallons. So, how is 43.1MPG (5.46L/100Km) possible?:confused: (If it's imperial gallons I apologize in advance)

Have you stripped the interior of the car, removed the seats, removed the spare tire, stripped the paint, ... ?

I mean, Toyota rates the car as follows:
Manual (city/hwy) 6.9/5.5
Automatic (city/hway) 7.0/5.6

Real world results are normally worse than the manufacturer spec sheet, yet you are reporting BETTER results than the 100% hwy numbers. How is that possible?:confused: :confused: :confused:

[argylesocks]

my BEST tank was 44.2mpg (US). this was a full tank which included a drive to Vermont with my girlfriend, my bike/wheels on the back & all my gear in the car.

I drove 58-60mph the whole way & coasted in neutral down every hill.

This summer i was consistently getting 40-42mpg without too much effort other than keep my highway speeds to 60mph & coasting when i could.

Lately, due to cold weather, warm-ups, & some faster speeds, i have been more in the 38-40mpg range... still acceptable :)

[swng]

Under very very favorable conditions, I guess it may be possible to get better than published fuel economy. However, with the traffic conditions that I have to go through daily, I won't even think about it.

[gonzo452001]

yes US gallons totaly stock except for the scan gauge there was about a 150mile trip on that tank also and i hardly ever drive over 60mph and alone most of the driving got 42.5 on the first tank use sunoco 87 regular gas i am real happy with the car

[spkrman]

over a 400 mile trip, and some 30-40 miles of city driving... 36.6 mpg. driving conservatively, motor only has ~1600 miles on it, 1600 after the trip that is.

yep, mileage is also improving as motor continues to break in, first tank was approx 32mpg driving conservatively.

The past few weeks have been sorta abnormal - lots more driving than usual. Even though i've done over 1500 miles in the last week, its more than likely that I won't go over 12k over the next year. Although, a trip to NY is coming up... 1600 more miles lol.

[keesue]

My first tank was actually 35.8/mpg and the second tank is 35.9/mpg. This is with two people car-commuting with me, 90% freeway, 65mph average with some inevitable stop and go. I am completely amazed at this. This is coming from a car that averaged 19/mpg and which required premium fuel. The savings is tremendous. I am pleased to say the least.

[tds12]

First 4000 miles 39.5 MPG. Manual transmission. 80% highway, 60 MPH.
Follow other vehicles when possible...My scanguage indicates up to 10 MGP improvement when following a large truck (6 car lengths).

Thanks for sharing!

now we'll have a forum of semi tailgaters... :)

[swng]

:bellyroll:What a quick mind and good sense of humor:w00t:!
Surely we have to drive safely. In fact, following a truck can reduce drag but following too closely may also render it difficult to judge the traffic conditions ahead, which may lead to abrupt stopping and heavy braking (if not an accident) and thus waste of fuel. I am sure the member who just shared his experience never intended to recommend following too closely. I think he just mentioned his scangauge observatons for academic interest. IMHO, we should always keep at least a two-second distance from the car in front. An even longer distance should be in order in unfavorable conditions.
This thread is useful because of all of you who contribute to it:thumbup:. Please visit and post frequently.

[BMGYaris]

yea, i have read somewhere somethinga bout a car length for ever 10 mph, but whatever. Anyway, we should all write mythbusters. It would be interesting to see exactly what distances behind a big truck change mpg and how much per distance. My initial thoughts are that if you drive far enough behind the truck to have decent visibility, then there wouldnt be too much advantage as the wind would have...i dont know..repositioned?:) anyway, lets send some emails to mythubusters with this one.

[spkrman]

it would also be uncomfortable for the truck driver to have a lil car that he probably can't see behind him. Maybe the biggest gain in MPG you can get is a CB radio? :)

[swng]

Just for academic discussion, and don't do it a home. Professionals do agree that following a big truck in front can save fuel. Please read this review (to save time, please go direct to the paragraphs under the sub-heading "Fuel economy run"):

http://autos.msn.com/research/vip/job.aspx?year=2007&make=Mercedes-Benz&model=E-Class

Here is a quotation from that web page:

"We used a different strategy when we got on the highway, though. We sought to draft behind large vehicles—in actuality, tucking closely behind a pickup truck towing a camper, and later getting behind a semi. But this meant we couldn't see much ahead of us, and we were required to match the speed of the bigger vehicle directly in front."

Note in particular that there are comments about the disadvantages of so doing in the same paragraph. For daily driving, I suggest safety first.

More discussions in this and other aspects of fuel economy are welcome, friends!

[ECHOKnight2000]

I read that following a truck closely you can coast but its very ideal conditions, meaning the draft of the truck pulls the car of course bigger cars it would be harder but for the sake of the Yaris...obviously this is dangerous. There is a point where the truck's draft creates a turbulance so the car is shaking, sort of like a jet stream (not saying it is just a comparison). Sorry I'm not to knowledgable on the techincal words. Anyway you have to follow really close and for the sake of mpg, no not worth it, you're asking for trouble or a death sentence. Just my .02:iono: :thumbsup:

[tds12]

You don't need to be real close to see a difference in the scanguage MPG. 6-10 lengths. This is way farther back than typical freeway driving in Seattle.
Also it doesn't have to be a large truck any vehicle that disturbs the air in front of the Yaris. Larger vehicles work better but it is a noticable decrease following any vehicle.

[spkrman]

scanguage is definitely on my list of things to get... now a very long and expensive list!

[nsmitchell]

Holding steady at 31mpg. I am not really driving for mileage. Lots of lights, lots of stomping on the gas. ;) I am still waiting to take a good long road trip to check out maximum mileage. Hopefully around 40 something.

[lispat]

The Yaris engine is designed to run on the fuel that is recomended in your manual. ( different parts of the world ) Unless you can change the timing and fuel maps etc. it won't run any better on a higher octane fuel. There are more additives in better fuels such as Chevron has more Techron in their higher graded fuels.


I tried higher octane in my Tacoma, it doesn't like it, I would stay with what Toyota says, they have a lot of expertise. If not we'd be driving something else. Ooooh, I wouldn't like that.:smile:

[spkrman]

premium did fine in my yaris, no major gain anywhere though.

[nsmitchell]

premium did fine in my yaris, no major gain anywhere though.
Premium gas is ONLY for high compression engines. To put it in your Yaris is truly wasting money. In the following article, he even mentions "The Family Toyota".

http://www.straightdope.com/columns/041008.html

[fearturtle44]

I would recommend a fuel injector cleaner every 7500 miles. Just put in an empty tank prior to fill.

Kevin

[keesue]

I concur with the statement: "Premium is for high compression engines". The Yaris is not a high compresson engine and does not require premium. It does not suffer detonation which is the sign of an octane level insufficient to support fuel burn over explosion (detonation). It is a complete waste of money. As to fuel system cleaners, if one exclusively uses a high quality fuel, such as Chevron with Techron, it is less of a requirement. Most new vehicle certifications for emissions and fuel efficiency ratings are performed using Chevron (by the way). The difference in cost between grades can be significantly offset by using a fuel system cleaner when using lower grade fuel.

[bigsky2]

Right now my mileage is approximately 7.5~7.9L per 100KM.

I usually fill up with two or three bars remaining and calculate the mileage from the amount I travelled on the trip and the amount of gas that filled up the tank.

I did run the gauge to the last bar last week, and I filled up. It was about 38 litres or so and my trip was about 500 km. Works out to about 7.6L per 100km.

Not too shabby, but not the best either. I don't think I can achieve 6.9L per 100KM (stated City mileage by Toyota) unless I turn my car back into its stock form.

Yeah seriously, WTF is all that. I just want a plain answer/response like 30mpg. Not no 1324L per 2398443something.

Komrades, I repeat.

7.6~7.9 LITRES PER 100 KILOMETERS. WINTER MILEAGE.

BRRRR.

[swng]

As the starter of this thread, I am pleased to be at your service. 7.9 liters per 100 km is about 29.87 mpg (US) or 35.7 mpg (Imp). Here is a useful link to help do the conversion (It was recommended by another member earlier):

http://www.roity.com/petrol/metcalc.html

Here is another one:

http://oee.nrcan.gc.ca/transportation/tools/fuel-trip-calculator/fuel-calculator-input.cfm?attr=16

If you use the second one, which is Canadian, you can type in your numbers, get the calculated results and then copy and paste them to your next post on this thread. I think if you only copy and paste the few lines containing your fuel economy, there should not be any copy rights issues, but correct me if I am wrong.

[eTiMaGo]

Komrades, I repeat.

7.6~7.9 LITRES PER 100 KILOMETERS. WINTER MILEAGE.

BRRRR.

What's that in barrels per fathom?

[bigsky2]

I don't know if the Lower Mainland, Vancouver in particular, is receiving the winter blended fuel, but my mileage has worsened since the end of summer.

But at the same time, my car has changed as well, so I am sure that also contributes to the poorer mileage.

[bigsky2]

[Billstein]

My first tank on the silver car was 35 mpg us ,
My second was on a road trip ok I was in a hurry.
I recieved a bit lower 29 M.P.G. us
I was driving around 80mph to 85mph +
I know very sad.:frown:

I just picked up a 2007 3-door 5-speed a few weeks ago, and I'll be tracking my mileage closely as I've done with all my cars in the past. A year ago I drove a 13-MPG SUV, sold it and went to a 50-MPG Diesel Golf, and now I'm curious to see how far I can push this Yaris. First tank got me just a hair under 30 MPG, but I have no idea if the tank really was full to start off with.

I've been using the same simple speadsheet forever, which calculates from liters into gallons, kms into miles, so I can see both L/100KM and MPG quickly. It also plots everything into a graph for visuals.

I only have 1 fillup so far, but you can see what the end result is here:

http://www.superjens.com/cars/Yaris-Stats/index.htm

If you want the spreadsheet for yourself:

http://www.superjens.com/cars/Yaris-Stats/stats.xls

When I had the 13-MPG SUV (two years worth of city/hwy/offroad averages), I drove across Canada and back in it one summer. With a few tricks and some really careful driving I managed to get 26 MPG average! That was with a bike and other junk on the roof.

I'm looking forward to some long road trips next summer in this little Toyota, my bet is I'll be able to squeeze 50 MPG out of it.

[swng]

Looking forward to reading your further reports.

[nsmitchell]

I got 31.5MPG the other day. Lead foot with about 50/50 city/hwy. I need to lighten my foot so I could get the 35-40MPG like everyone else.:wink:

[TDL]

Does your gas mileage get better once the vehicle passes the 1000 miles break in mark or ? My first gas tank I got 375miles, second one I got only 325miles, 3rd looks to be less. Not sure how anyone is getting 40+ mpg.

Slow starts, 65-70 on the highway.

I bought this vehicle specifically for the gas savings.

Liftback, manual.

Thoughts?

[stuffy]

it appears you are getting about 25 mpg right now, assuming you are filling up a full tank (approx. 10 galons u.s.).
this is exactly what i was getting a year ago when my car was new, and with winter fuel.

now, i'm getting about 34 mpg around the city with winter fuel.

I had a similar experience to yours i will share later. The only thing i can think is that there is a thread on here that shares the experiences of one guy who ran out of gas and it caused him to get someting like 19mpg for his next couple tanks. It turns out that there are sensors in the tank that adjust your fuel consumption somehow for very low feul levels. Apparently that is one reason why the manual recommends filling up when you have two bars left.
Also, according to the NHSTA every 10mph extra you travel on the interstate cost an average of 20% fuel economy. Thus if you are going 70 instead of 60 you will use 20% more gas. That isnt exact im sure, but you can get the idea it is a pretty handsome number.



My first tank got 29, i filled up and i only had 0.8 gallons left in my tank, my second got 25mpg, my third got 23 (doing about 80-85% highway at 60mph steady) and then i filled it up, took a road trip on the interstate and i got 34 mph each way going over 70, probably averaging 75 mph, a little 85. (only 100 miles each way though). Earlier I had taken it in and had the transmission inspected and everything checked out ok. My theory is that when we run the fuel so low it messes up the sensors, but after a point they automatically reset--seems to have happened to me as after i filled up again i got such huge improvments driving so fast on the interstate. There were a couple other people that talked about this on here elsewhere.

[eTiMaGo]

I agree about the low fuel thing, kinda experienced it myself (i think)

When I had upgrades done to the car, the guys at the workshop left the engine running most of the time, and it actually ran completely dry.

Once it was refueled, and the car back on the road, I found I had crappy mileage too, half a tank only lasted about 150km.

Then, a couple of days later, I was on the highway, pedal to the metal in 5th, when the air/fuel sensor meter I installed pegged the needle on very rich, and the warning buzzer went crazy for a little while. Then, the meter went back to normal, and so far, normal mileage seems to have returned.

I'll be sure to refuel before the gauge shows two bars from now on :wink:

[Nutzoids]

Alright I have a US Yaris HB... I have 2 bars left and I want to find out what my MPG was... What equation should I use? How many Gallons of gas fit in that tank? Do I just refill the tank and minus that number from the size of the tank then divide that by the amount of miles I have done? There are too many numbers here with the Metric/IMP/ US conversions…I’m slow and need to be explained things slowly!

:evil:

[hystria]

100% highway at 3000rpm (70mi/h)
39mpg

100% stop&go city, moderate driving, cold weather+snow
26mpg (35 miles on a bar)

that's for a 4000km on clock, 5 speed Hb with original oil/filter

Just changed oil to synthetic & waiting to see if ther's any change in mpg

[BMGYaris]

100% stop&go city, moderate driving, cold weather+snow
32mpg (35 miles on a bar)




What do you mean by on a bar?

[hystria]

What do you mean by on a bar?

fuel level bar. of course, this is just a first approximation of my city mileage as I just moved into the city. i'll be back few tanks later for a more precise mileage :smile:

[boris13]

And are you using Imperial gallons or US gallons?

[stuffy]

nutzoids: just fill the tank, note how much fuel was put into the tank and how much distance was travelled by noting on the odomoter,
i have a little pad i keep in the car and once the car is filled, i write down both numbers and do the math at home.

divide the distance travelled by the amount of fuel used.

it's good to average this over a number of tank fills to get a better idea of fuel economy.

[hystria]

And are you using Imperial gallons or US gallons?

your right! topic edited :wink:

[Typer73]

Nutzoids-- I also have a US LB (averages 33 mpg). I always zero out my Trip A gauge when I fill up, saves me from having to do too much math. :eek:

I get a receipt that shows gallons used and write down the mileage from Trip A on it with the pen kept in the "handy-dandy driver's side glove box", then zero it out for the next fill-up. Do the dividing math at home with a calculator!

[Racer X-8]

Q. What do I do when I just want to do a partial fill, like, say, throwing $5 worth into it?

A. DO NOT zero your trip odometer. Save your reciept(s) and when you finally DO fill it up, record your total miles from the trip odo and zero it. Add-up your total gallons from your reciepts. Divide the total miles by the total gallons. There you go, as accurate as anything, no estimating.

btw, I'm still getting 36 mpg avg., and it's pretty consistant, like my graph posted on 10-2 shows.

[wibrian]

1st tank 32.6 mpg, 2nd 35.4 Hope it keeps going up

[why?]

I can't emphasize how much slowing down can help your gas mileage. For gas mileage purposes, there is no reason to go over the speed limit. Add that to accelerating slowly, and doing everything possible not to use the breaks, and being really patient all the time. Even going 80 mph for a few miles can drop the gas mileage significantly on a tank of gas that was otherwise averaging 55 mph. It all comes down to how much gas you want to save against how slow you feel comfortable driving. The Pulse and glide method works as well, but you usually don't want to go to much lower than the speed limit, so its use is limited on public roads.

Everything matters when it comes to gas mileage. Weather, Tire air pressure, weight in the car, if you let the car warm up, how much you let the car rev before shifting, any accessories you use in the car, how hilly or flat your usual driving spots are, stopping in traffic, braking a lot, etc.

BTW, I ran my tank completely dry once by mistake, and it did not seem to hurt my fuel economy at all.

Having a tach really helps with gas mileage. Knowing when you shift and how much you are really accelerating can help you go slower and save gas.

[mutatio]

I thought you folks might enjoy the opportunity to bolster the numbers for the yaris.

[eTiMaGo]

Whoohoo 19.1MPG - 12L/100km :cry:

Warming up the engine properly, short trips and being stuck 2 and a half hours in a traffic jam certainly don't help... Gotta love this city :tongue:

Can't wait for my road trip for the holidays... that should give us better numbers!

[swng]

I know how you feel. I encountered a serious traffic jam this afternoon. It is going to hurt the result of this tank.
Can't wait to know about how your car performs in your road trip. Bon voyage!

2,200 miles here. I bought it on November 6 with 8 miles on it.

My boyfriend and I drive my Yaris all the time rather than his 2006 Honda Civic coupe! :biggrin:

[nsmitchell]

34.5 MPG on a trip that was about 120 miles of highway with the wife and my 2 kids, the rest city. I can't wait to take a trip from Richmond, VA to Charleston, SC. That trip will probably exceed the hwy rating of 40MPG.

As of the end of Oct, I've had my Yaris a full year. Good time to present a summary of results :wink:

Distance covered over 1 yr was 16,826.8 km. Year-long avg fuel consumption works out to 6.51 L/100 km. That's 36.11 mpg for the Monopoly players out there, and 43.37 mpg for the poker players.

I'm satisfied w/the results. Fuel expenses were very reasonable (a quick tally says ~CAN$900). Dare I suggest however, that the real way to save big, is to minimize taking the car out of the garage at all.

Overal usage was approx 2/3 hwy & 1/3 city. Burning 10% ethanol fuel for all but ~4000 km (regular gas used there).

Highest recorded fuel consumption was 7.52 L/100 km (a period of more short city trips in the winter). Lowest was 5.48 L/100 km, achieved on a 500 km summer hwy trip.

As I roll into my 2nd year, and with the arrival of winter, fuel consumption is up vs. the summer (as expected - now sitting at 6.5-7.0 L/100 km). Equipment changes vs. last year include a switch to synthetic oil, and winter tires. Cheers.

[nsmitchell]

31.5MPG 50/50 city/hwy and I was not going easy on it.

[eflb55]

I'm getting really upset at my bad mpg in the city. I do drive like an asshole, and on average end up around at least 4k to 5k rpms on side streets. If i feel like a nice stroll I might try to stay below 4k. I haven't really been writing anything down but I'm sure I'm under 25 mpg. It has been getting pretty cold out and I try to give the car about a minute to 2 minutes to warm up, so I feel that might be lowering the rate. I keep worrying that because I drive like I do that I'm somehow screwing up the engine or something....


Last time I went on the highway for vacation which was during the summer, I ended up getting 41 mpg. But that was before I started driving like a complete asshole.

[stuffy]

eflb55, so are you mad at yourself for driving like that, or mad at the car for not getting good mileage while you are driving like that?

there is no need to let the car sit and warm up, just dont' push it while it is warming up.

[hystria]

no doubt, always shifting 4k & UP has a price to pay. There is no need to "warm up" 2 min. In cold weather the engine needs a few seconds to get lubricated, then it warms up much faster if the car is running at moderate rev (say 3000rpm). Otherwise, warming the engine at idle will wear it more because it runs more time at colder temp as the engine takes a lot more time to warm up when idling.

[Kaotic Lazagna]

wow, really can't remember if i replied to this thread or not (too lazy to check), but i average around 40 mpg, majority being freeway. best i have gotten after calculating after filling up was around 50 mpg, i think.

It must be a Michigan thing... When I drive in Michigan I do not get as good as gas milage as when I drive in Ohio... must be the air:biggrin:

[Typer73]

Just got back from an 800-mile round trip, N. GA to N. FL in my automatic LB. got 35.5 mpg down to Valdosta, GA, 34.4 mpg from Valdosta to Jax & back, and 36.7 mpg back to N. GA. Running the A/C, running with the traffic (80ish mph) and a 20 minute stop & go traffic jam in Gwinnett Co, GA. So maybe it's not what is listed in the specs, but I still love it.:thumbsup:

[robcrowell]

Just took an over 350 mile trip, mostly highway miles. But I got about 45 mpg on my Yaris Sedan. Most of the time I was going 85 with traffic! Over 12,000 miles and loving this car!:thumbup:

[Racer X-8]

I always work on the knowledge that an idling engine doesn't develop much oil pressure, so, the cold, thick oil isn't getting to and lubricating the upper moving parts (like the valve train) very well. So, I fire it up and go - not hard - right away, no warm-up.

eflb55, you need to also own a Mazda RX-8 like me. It thrives on high rev's, going to 9k so happily. It also only gets about 18 mpg on the average, so you'll really have something to complain about. Maybe too then, you'll drive your Yaris the way it was intended to be driven, and you'll get your 36 mpg average like me (14,500 mile average mpg, that is...) and maybe you'll be able to enjoy it for a real long Toyota amount of time. :smile: and maybe you won't be one to find out why the Yaris got poor ratings lately in crash testing.

[eflb55]

true that. Once I was sick and my nose was blocked up for a couple days, and then I started smelling again and everything smelt like garbage/crap. I then realized how bad it smells around detroit. nasty.

It must be a Michigan thing... When I drive in Michigan I do not get as good as gas milage as when I drive in Ohio... must be the air:biggrin:

Other than that I actually attempted to stay below 3k today. It was quite a challenge.

can you grow up a bit when writing to others on this board, sorry everyone doesn not own a RX-8 like you, does that make you feel special you have a vehicle that is made by Ford/Visteon/Auto Alliance... I realy hate it when people come in here and think they are better than everyone else because they have something everyone else could easly have.... if you had a Ferarri, HELL yeah throw it in people's faces, you may as will told us you had a real fast Taurus or something like that....... sorry for the vent, it just bothered me a bit

and to keep on topic, I have been gettin 30-32Mph, but I drive her hard on the e-way

[Racer X-8]

You sir, are a jerk.

First off, I'm easily old enough to be your daddy, and if I was, I'd slap some sense into you the hard way, if it's at all possible for you to gain any semblence of civility, you seem to be now beyond help.

Secondly, I only mentioned my owning my Hiroshima-developed/hand asembled rotary engine - powered, Hiroshima-built vehicle because, (a) as you already know, rotary engines redline at 9000rpm, actually rev to 9500 easily, and eflb55 likes to rev high, and, (b) if he thinks something under 25mpg is bad, he would really have something to complain about with the 18mpg that he would only get. Hmmm, if I was "throwing it in people's faces", why would I so blaringly be exposing one of the oh-so-few downsides of owning one?

Thirdly, it seems that you have a problem with people who are happy with what they have been thus-far able to acquire. If I were to have mentioned my Ferarri or my real fast Taurus or something like that....... would you have behaved any more civil? Just because I have experience in matters pertaining to another one of my several cars, doesn't mean I'm bragging about owning it, and even if I was, you would STILL have no right to reply in the way you did... My guess - you were banned from the RX-8 forum for posting in a like manner, where they rightfully so have little tolerance for your type.

Fourthly, doesn't this site have admins? I made the complaint last night, but I guess they don't care. That's just plain sorry. Need I refer to the Forum Rules? http://www.yarisworld.com/forums/showthread.php?t=2910 And not only do you post extremely foul language, which I am completely offended by, due to my religous beliefs, you have extremely foul language in your sig!

Fifthly, oh, I was going to comment on your, oh, nevermind... :bellyroll:

[BMGYaris]

WELL we all hear what you are saying racer, but, since you sound like a man who pursues wisdom reflect on yourself at the same time and be open to what you may find there. I am sure you are a decent guy, and i bet you are hard working as you took the time to look up a rule over a grudge you had against a silly rebuke post (id have been too lazy to actually look it up, even had i wanted to reply to him :P) but, consider yourself a bit as well:

you'll get your 36 mpg average like me

If you dont mind look at that above post and consider how there might have been a more effective and polite way to convey your message? Was the focus of your message something that required referring to yourself so often, or was it simply about appreciating what you do have and understanding how things can be much worse off?

(in further reflection, imagine if i had responded thusly:

I always try to speak kindly and to the point. You should try to think about what you said like i always try to do.
Racer X-8 You should have a beautiful japanese girlfriend who's parents always try to analyze and judge you for your worthiness, like i do. Then maybe you would learn that you can't always talk about yourself when you want to make a point.
Then You would have some experiences in being delicate and understanding other people. That way, you can grow into a better person :smile: and you can get along better with people; like me.)

The point: look at yourself, you have faults, fix them, persue wisdom--become wise, not angry.

(and if you want to reply please PM me) EDIT: i didnt pm you because i was too lazy :P been planning to post my results here, so what the hell take out two at once. But either way you talked about yourself way too much.


Now that i have had my tirade (notice: i would remove the top portion of this post if i was moderating this site, so feel free guys:smile: , as it really contributes nothing to the site)

My mileage during daily living has been 22 mpg. My long trip highway commutes is 34mpg. It makes me very sad, but oh well, guess short trips and moderatly heavy feet and a fat body will do that to you:thumbdown:

and no, her name is not Yaris:) and she is beautiful, got her on the rebound while she was studying abroad--easy pickings.

[Pars]

BMJYaris, I hope that beautiful Japanese girl of yours isn't called Yaris. :biggrin:

I'm another lead foot driver and it shows by the condition of my tires. At 30,000km, they're already worn out. Anyways, I'm getting better mileage then eflb55. My worst is about 30mpg (US), but my 5spd Yaris gets very few cold starts, so no short trips on a cold engine.

I have to agree with eflb55, it's hard to drive the car conservatively when it's so much fun to drive. Also, I think the electronic acceleration likes to hold on to the speeds, regardless it you're in a fuel conservative mode and want the car to coast while slowing down. So, if the car doesn't want to go slower, hey, who am I to complain? :biggrin:

[Racer X-8]

A person who is trying to speak of lessons learned thru personal experience will usually use the words "I" and "me". Duh? Take it or leave it, I'm totally not surprised by the want of another hotshot to take what I had to say and turn it against me. Anybody else? BMGYaris, why didn't you PM me?!?

Oh, and, um, Pars, uh, {a friend of mine(?)} feels the same way about the Yaris being fun to drive.

[Pars]

Respects Racer X-8 :respekt:

I usually try to get a sense of a person's driving attitude by the cars they driver. And I doubt a posers would be driving an RX-8. I do know of a Cougar in an automatic RSX. But the RX-8 is the kind of car for enthusiast (similar to the S2000 but for much less).

[acrbill]

I finally got tired of waiting to put more miles on the car so i filled up with 3 bars remaining. This is the first full tank of gas and the car has 240 miles on it.
I bought the car with 40 miles on it and did not top the tank off for a few days.

With 99% true short trip city driving I got 25.89 MPG. Once I get back to work I should get a much better idea of what to expect from a mix of city/Hwy MPG.

This is a 5spd Hatch.

[superjens]

Doesn't matter what I do, super light, quicker high revs, all city or all highway, so far my first 1500 KMs are just shy of 30 MPG.

Call me dumb, but I've always thought gas was gas. We only have 2 readily available gas stations in our small town, a BP and a Shell. Due to my mileage difference on a recent trip I decided to test out mileage differences using each brand. On BP (always 2-3¢ per gallon cheaper) I average 32-34mpg, using Shell this week I got 36.6mpg. Huh?:iono:

Personally, I like using Shell in the winter and Esso in the summer. But, the difference in fuel consumption hasn't been great enough for me to prove or disprove one brand over the other, since there's very little control over my driving style (it changes with my mood and I tend to be moody) and I don't do the same route everyday.

But, the difference in fuel consumption hasn't been great enough for me to prove or disprove one brand over the other, since there's very little control over my driving style (it changes with my mood and I tend to be moody) and I don't do the same route everyday.

Shell is definately the best. With the new Tier 1 gas I notice better gas milage.

[Black Yaris]

Call me dumb, but I've always thought gas was gas. We only have 2 readily available gas stations in our small town, a BP and a Shell. Due to my mileage difference on a recent trip I decided to test out mileage differences using each brand. On BP (always 2-3¢ per gallon cheaper) I average 32-34mpg, using Shell this week I got 36.6mpg. Huh?:iono:

Many cat manifactures tell you NOT to use BP fluel due to all the extra additive that can actually harm your vehicle over time

Well, 40 miles for 30¢ more per tank ... hmm, I'm not that dumb! Shell it is!

Here is the result of my latest tank with fuel from Petro Canada. Canadian currency used:

Fuel Cost
$36.01

Distance travelled
535.5 km
332.76 miles

Fuel Amount
34.83 litres
9.2 US gallons
7.66 Imperial gallons
Cost of Fuel
$1.03 per litre
$3.91 per US gallon
$4.7 per Imperial gallon

Fuel Economy (30/70 city/highway)
6.5
litres per 100 km
36.16
miles per US gallon
43.43
miles per Imperial gallon

Mileage Costs
6.7246
¢ents per km
10.82
¢ents per mile

The result appears to be good, considering that it is winter. Possible reasons being that the guy who assisted me in the full serve only gas station might not have filled up close enough to the top (that could affect the calculations in that the distance would appear to have been covered with less fuel) and that the last week or so was quite warm.
BTW, I have refilled with Shell Bronze to see if a better result could be achieved.

[stuffy]

i drive past a fuel depot where the trucks refuel to refill the gas stations, and strangely, i've seen trucks from just about every station refilling from the same tanks.

[Jem_hadar]

What do you consider accelerating gently or non-gently (ie. wasting fuel by accelerating TOO FAST/HARD from stop signs or lights!)???

When I accelerate, tend to keep it between 2,500 and 3,000 RMP before shifting into 2nd... 3,000 being the ABSOLUTE highest... im usually at 2,500 or in the middle.

Is that wasting unnecessary gas in yall's opinions?

Lets get some thoughts here, because I'm wondering. Am I starting harder than most ppl and maybe thats why I'm only seeing 28-30 MPG US per tank??? :iono:

[graywolf_14]

Well actually u can shift to low in the rpms.

[graywolf_14]

if they are advertised at over 30mpg in the city y are people getting so crapy mileage?

[Jem_hadar]

Well actually u can shift to low in the rpms.

I know I can shift to 2nd and other gears SOONER keeping the RPMs below the 2,500 - 3,000 range. But I dont really wanna. Feels to weak entering 2nd or 3rd or 4th gear when I've shifted at 2,000 RPM.

Just curious if me shifting into 2nd and other gears at 2,500-3,000 is maybe a main cause for why I'm only seeing freaking 28-30 MPG US???

if they are advertised at over 30mpg in the city y are people getting so crapy mileage?
I wonder too!!!!

[spkrman]

Just got back from an 800-mile round trip, N. GA to N. FL in my automatic LB. got 35.5 mpg down to Valdosta, GA, 34.4 mpg from Valdosta to Jax & back, and 36.7 mpg back to N. GA. Running the A/C, running with the traffic (80ish mph) and a 20 minute stop & go traffic jam in Gwinnett Co, GA. So maybe it's not what is listed in the specs, but I still love it.:thumbsup:

this is on par with what I've seen over the 6000 miles the car now has.

Just waiting for it to warm up, so I can get a few more mpgizzles :)

[eTiMaGo]

I used to shift at 3000rpm. City mileage was a constant 24mpg (US)

I'm doing right now a test: shifting UNDER 2000rpm. Will let you know what the mileage will be :smile:

[graywolf_14]

Yeah but in such a low hp car it will be like driving a 4whl moped unless u shift min 3k. Least that is how it was with my festiva and my dsm.

[d2dailly]

Sure does, if u shift around 2,000 RPM... god, it feels so sluggish and weak in the next gear until ur RPM slowly crawl up a bit.

Somwhere just before 3,000 is usually the ideal spot for me for power for shifting

[hystria]

Somwhere just before 3,000 is usually the ideal spot for me for power for shifting

I agree, I do so usually, but then I get less than 25mpg. Shifting between 1500-2000rpm (and cruising at 1500rpm) make it slower, true, but not too slow, it's just like driving it smoother and let me say that I usually quite keep up with the traffic.

I understand. Thanks!
Still, I change from brand to brand from time to time hoping that the different additives that are put in by different oil companies will help make a small difference:smile:.
What I am doing is, of course, experimental. No conclusion yet.

[bojim]

I have a 07 4 door auto. I average 38mpg and have got 41 mpg on a road trip. I'm very pleased with this.

[Marilyn2006]

Hi, first reading after 300 mile breakin period. Auto, sedan, about 90% stop and go, 34 MPG US average. I'm very pleased -- will be much higher when I start communting back to work and get some highway miles on it.

[swng]

Your car's fuel economy looks very good for city driving. It will be great if consistency can be maintained over time. Any improvement will be even better.
It will be appreciated if you post your future mpg numbers here periodically.

[superjens]

I'm now over 2000 KMs total mileage, and my MPG average for this last tank is now up to 36 from a previous average of 30.

I'm positive I can get it up to 40 MPG on this next tank, since the first half of the last one had a fair bit of city stop/go, and I was heavy on the pedals for a few trips to see what it could do. Only the second half was in econo-mode, shifting at 2000 RPM and being very gentle everywhere.

I respect your opinion. It may not be too meaningful to state mpg numbers down to the tenth of a mile. Those numbers can hardly be really that accurate. However, when one uses fuel economy calculators like those linked underneath, one will more likely than not get numbers that are in fact calculated down to the tenth of a mile. I guess few people will spend extra time to round the figures up, or down. Incidentally, the fourth one, which is from the US Department of Energy, actually states examples in numbers calculated down to a tenth of a mile. So, I won't blame those who post numbers with decimal points:smile:.

You should see what the Prius forum folk do to check their mileage. You'd think they were rocket scientists.:laughabove:

[Racer X-8]

Oh crap. My MPG dropped from 36.0 down to 35.9 Probably because my wife drives it to work now instead of me, since mid-September, and she uses a lot more two-lane, whereas I was amost all 4-lane. Still totally not too shabby IMHO. I just switched oils on an oil change that I did this past Friday - from Castrol GTX 5W-30 to Mobil 1 5W-30. We'll see what that might do... stay tuned...

Oh, BTW, that 39.0mpg blip on 10-29-06 was from a trip we took to Hotlanta - mostly all trip miles on that tankfull - three people.

You're looking at 15,000 miles total. Gallons are US.

[nsmitchell]

My Odyssey got 24.8MPG on my trip to NJ this weekend. No too shabby. I'm using Amsoil Series 2000 0W-30 oil. 62K miles on my Odyssey.

Racer X-8, Where did you import that graph from?

[Racer X-8]

Racer X-8, Where did you import that graph from?It's an Excel chart that I made up. I track all of my cars the same way, each one has a separate Excel file, different only in the data input from each fill-up. I've been using it since 2001. Works pretty good. The files also chart gas pricing and total mileage.

Inputs required - only done for complete fill-up's:
1) Date
2) Total mileage
3) Trip mileage since last complete fill-up
4) gallons (if you had one of more partial fills since your last fill-up, add-up the gallons for a total)
5) $money spent$ (again, if you had one of more partial fills since your last fill-up, add-up the $$$ for a total)
6) Kind of gas (like, "Shell regular")
I also have a remarks column for anything that might pertain, like oil change info, or like "Trip to Hotlanta"...

The gas pricing chart is pretty cool. You can see how they're playing the general public like a bunch of fools. You see a lot of short-term surges. The cost surges alarmingly high, then it receeds to calm the masses, but not all the way back. One after the next. After a while you see how the receeding not all the way back causes the long-term trend of increased cost that won't ever receed.

yep... its a way to "safely" raise the prices and still gouge the hell out of us in the meantime...

[Racer X-8]

Okay here it is, hehe. A couple things I can point out:

The downward trend in the beginning is mainly I think due to the drop below $1 per gallon just after the 9-11-01 attack. The price of gas dropped un-naturally low for some reason.

The major spike in 2005 was from the shortages due to Katrina.

The last thing I see is - it looks like we're in for a major price hike again... soon... :frown:

US $$$ per US gallons. Regular gas - the cheapest I could fairly easily find.

and that gas has across the board been .20-30 cents cheaper than mine.

i dont understand how people buy big SUV's to commute and run little errands and such... how can you justify the ridiculous gas costs, while gas prices are only goin up?

And how can the cost of gas rise, and rise, and rise for no apparent reason? They make more in one second than I'll make in my entire life... lol

[Jem_hadar]

Money isnt an issue for a great deal of ppl. Who cares if gas is $100+/L...

So many individuals make enough money that the cost of gas isnt a deterrent. That gas prices have risen greatly hasnt had an real or concerning impact on their way of life whatsoever.

I can see why most ppl simply dont care. They enjoy all the added fancy luxuries and power and pride associated with their large sedans or large SUVs. Why switch to a compact, more fuel efficient car and lose many of those features which you highly value, if the added cost of fuel doesnt impact you? Increased gas prices cant be a big deal for everyone.

I definitely bought my Yaris bc gas prices matter to me, as it does to many ppl on here, but we're definitely not the entire population. If you got money, who cares what you're paying in gas. They drive what they want to drive... fuel efficiency is not a factor they need to consider (at all) in their vehicle purchase!

I have come across an article about understanding fuel economy ratings. It is admittedly long but I would recommend it:

http://autorepair.about.com/cs/generalinfo/a/aa022501a.htm

[Racer X-8]

Good article. It mentions one thing that I see people do a whole lot that just really irks me - when they leave their car idling. Heck, I even turn it off when I'm in a line at a drivethru! It's just wasting gas (and poluting), letting it just sit there idling. Some people think that starting your engine takes some equivalent amount of gas as idling it for like 3 minutes or something. How the heck could it? That's so un-true.

[Black Yaris]

The downward trend in the beginning is mainly I think due to the drop below $1 per gallon just after the 9-11-01 attack. The price of gas dropped un-naturally low for some reason.



the complete opposite happened here in Toledo, the gas prices skyrocketted, to over $3 a gallon, wich was unherd of at the time

[stuffy]

well it might be a good idea to start caring at some point....i'm thinking along the lines of the environment as opposed to gas prices.

comfort of a large car is nice, but breathable air is better.

i saw an insect outside today, in canada, in january!!!!

racer-x, that's great that you are conscious of the idling engine,i shut my engine off at lights that i know are long ones, sometimes i shut it off and coast up to the light.

[BMGYaris]

you guys should probably start a new thread or something if you are going to keep talking about gas prices, but i wanted to put in my 2 cents anyway. a number of things can cause increased gas prices. Natural disasters can cause for a temporary shortage of resources which will obviously increase prices. Dont forget inflation when looking at prices, the price might be higher, but the actual expense might be the same. But, most importantly, it is a natural resource, and one that is deplinishing and is aquired from regions that are very politically volatile. Further, as the quantity of fossil fuels decrease it becomes significantly more costly and dangerous to aquire--and it also demands that we locate and build new facilities which will obviously cause for increased prices as well. And finally dont forget taxes are sometimes raised as the environment continues to be get worse.

Thus you have inflation, natural disasters, wars, and the ever diminishing quantity of actual fuel (shortages, danger, difficulty, new facilities), and taxes. Looks like damn good reasons for the price to be steadily increasing to me.

I think that the increasing gas prices are less about the man sticking it to us, and more about the future getting ready to stick it to us real good. Perhaps it is a sign of just how dire our fuel crisis is and will certainly become.

[swng]

Valid comments gentlemen.
I agree that when we talk about fuel economy, we should not only care about saving gas (=money) for ourselves but also care about saving gas (=cleaner environment) for the whole world. Also, if the prices are raised in order to get money for the building of more modern facilities and the funding of more research programs to produce fuel that pollute less, I won't mind, well, as far as I can afford to pay. But.........:wink:.
Members will be glad to know that now many cities, including mine, have made, or are making, leaving a car idling for more than a few minutes illegal.

[Racer X-8]

the complete opposite happened here in Toledo, the gas prices skyrocketted, to over $3 a gallon, wich was unherd of at the timeHoly Toledo!
hehehe, sorry, I just had to XD

But yeah, really, that's very strange and I haven't a clue why? Different resources affected differently? Our fuel surely was affected by Katrina, sudden loss of like three pipelines that come from that area, we had stations closed from being out of gas. I didn't see that since the crap that went on in '74.

Stuffy, man, be careful about coasting with your engine off, without the engine running, you can use-up your power brakes - you know, the brake booster runs on intake manifold vacuum...? And oh yeah, you could loose your power steering and your steering wheel could lock, right?

About the environment and stuff, yeah, best to keep it outta this thread I guess. I gotta hit on one thing,,, the increased pricing is making it now cost effective to tap other petroleum sources that were up till now not cost-effective, such as the Canadian Tar Sands - that up there is boomtown going bonkers expanding like wildfire from what I hear... the local infrastructure is bursting at the seams from the population explosion of all that going on. It also made major leaps and bounnds with new technological breakthroughs on how to get it out of the frozen permaforst tundra up there, but the increased petroleum pricing is what sent it over the edge. I heard that our #1 petroleum source is now Canada. Somebody do the checking on that, I seem to recall that I saw that myself, but I still can't believe it myself. :iono: And there's more oil up there than all of the Middle-east oil fields combined. I can't believe that myself either...

http://en.wikipedia.org/wiki/Tar_sands

And there's a whole lot more oil that just isn't being touched yet either.

I'm all for getting away from petroleum as a fuel - it is most definitely going to totally run-out one day. But while we're going to something else, it's nice to know that we can kinda take our time and not be in such a chicken-with-its-head-cut-off rush about it. Hydrogen scares me still. Oh, ok, sorry... [lid put on it]

33MPG on Premium gas. I gave it a shot. 75% hwy and 25% city. I was going pretty fast on the highway trips. Not taking it easy at the lights either. :)

didn't feel like starting a new thread, so i will post my lifetime fuel economy below to give this post some legitimacy.:)

yeah racer x-8, i do believe that canada is now the number one oil exporter to the u.s., besides a lot of conventional oil,they have been expanding the tar sands project like crazy, without considering to a great degree the environmental impact of this rapid expansion.
as i understand it, the process to remove the oil uses up huge amounts of water, which is taken in from the athabasca river, then put back in a "not-so-clean" state, and the effect is a lot of environmental damage in an otherwise pristine part of our country.
this part of the country is not tundra-covered or subject to permafrost, so i think the expense comes from the method of removing the oil.

the averaged fuel economy for my car, in 14 months of driving is 34.4 mpg, mostly city drivin.

[swng]

Just a brief update below. Nothing to write home about but still want to report honestly. I guess the result has been adversely affected by the failure to put a full tankful of gas into the fuel tank at the time of refilling. Sometimes this happens when the nozzle stops too soon for one reason or another.

i think i have hit the wall with getting better mileage, most of my driving is short city trips (so basically the worst type of driving for fuel economy)

i figure if i can keep it above 30 mpg in the winter, then i'm fairly happy :)

[Yaris TTE JWRC]

I been tracking every tank i have used ever since i bought the car, and im not lying, i have 3.5k miles on it now (changed oil, no mods every thing factroy), and i have been getting twice 31MPG, and the rest of my tank got 30 MPG, it is about 3-4 MPG less of what the factory says, suppose to be 34 MPG / city, and 40MPG / HWY, i drive 70% HWY and 30% City,and i drive a 5speed, alos take easy when i drive just to see what the MPG really is on this car, but it is less than what it shoud be, any of you guys tracking ur MPG?? please dont lie about how much MPG u get, i wanna know what people and this car really get on MPG

[stuffy]

you will get better mileage as the engine gets worked in.
i've had my car for 14 months and 34.4 mgp is the lifetime avg i have achieved.
the best mileage i've had was 45 mpg this past summer on trips with 100% hwy driving.

[Blenjar]

How do you know how do you know all that? A computer in your car?

[stuffy]

[07WYarisRS]

Keep in mind when the tets are done for in town and hwy mileage they are done in a strait time with few cold starts and shutting the car off. if you fill up you car and drove it intown for a full tank of fuel without shutting it off you will easily hit the toyota mileage claims. Same with the hwy. If I fill the tank and drive it until empty with no stops or cold starts I can easily get toyota's cliamed mileage or better.

So much depends on the driving style, when you drive, where you drive and how often you start your car.
During the week our mileage sucks because the is driven 5 minutes from the house, at lunch the wife drives home, an hour later she drives back, then home again. 4 cold starts = 4 cold 5 minute drives. The car barely gets up to normal operating temps before it's parked again and this KILLS the fuel economy. but it's a far cry better then our truck was LOL.
The more short trips or in town the worse the mileage will be.


Also I get FAR better mileage driving then my wife does and we both follow the posted speed limits most of the time.
The difference is I tend to accelerate slower and coast longer, where she uses the brakes a lot more and has a heavier foot. When she drives the car is shifting aprox 500 rpm higher then when I drive.
Also the speeds you drive on the hwy make a huge difference. Drive 100kph and you will get better mileage them driving 120kph.

There are a few things you can do to improve the mileage as well. The biggest difference for our car was switching the fluids over to synthetics
Amsoil 0w-30 engine oil and Amsoil ATF. I can get crazy mileage (over 50mpg) if i drive on the hwy and keep it at 100-105kph and that's with an auto and car full of camping gear.
Do not over inflate the tires... so many people do this and think that it helps, follow the mfg's recommended tire pressure, it's on the inside edge of the driver door.

The difference is I tend to accelerate slower and coast longer, where she uses the brakes a lot more and has a heavier foot. When she drives the car is shifting aprox 500 rpm higher then when I drive.
Also the speeds you drive on the hwy make a huge difference. Drive 100kph and you will get better mileage them driving 120kph.

There are a few things you can do to improve the mileage as well. The biggest difference for our car was switching the fluids over to synthetics
Amsoil 0w-30 engine oil and Amsoil ATF. I can get crazy mileage (over 50mpg) if i drive on the hwy and keep it at 100-105kph and that's with an auto and car full of camping gear.
Do not over inflate the tires... so many people do this and think that it helps, follow the mfg's recommended tire pressure, it's on the inside edge of the driver door.
Thanks for that man.
Great comments, glad you posted that so I could read it.

[gr8yaris]

i hope that's the unbroken in mpg...
anyone broken in there yaris yet...???
anyone with 1000+ mile/1600+ km yaris yet...???

I already have 14,400 highway miles on my Yaris and I average 330-350 miles per fill up between 1/4 and empty flashing. I am guessing my mpg is at 35-36 miles.
FWIW, my Yaris is lowered, 295/40-17 tires, 5-speed tranny and I drive at speeds averaging 80 mph to keep up with NJ Turnpike traffic. This small car is high revving, nimble and stable but sensitive steering at high speeds compared to my 04 Camry.

wuddup wit dat? :iono: doesn't seem to match-up...

[Black Yaris]

FWIW, my Yaris is lowered, 295/40-17 tires...

How exactly are you stuffing a 295/40R17 tire under a Yaris?

[captainzerocool]

Because this is the fuel economy thread I'll post my last tank from my Camry.

I finally broke 30mpg. In the 5 years I've owned the car, this is the first time. That is nearly 95% highway at around 85mph. Nothing above 3000rpm. I've impressed myself with that feat.

And the car has 228,000 miles....

[foober]

It really appears most of the gas will be used in acceleration. So go easy on the acceleration. You can cruise when your up to speed on the highway and get probably close to 45+ miles to the gallon. But where most of the gas is used up is as I've mentioned in the acceleration to a cruising speed.

[Racer X-8]

I remember some testing results yielded a general statement that you use less gas by accelerating moderately than by accelerating very lightly.

Sure, accelerating moderately uses more gas than accelerating very lightly, but what makes it win-out in the end is THE AMOUNT OF TIME it takes to get you to your cruising speed. Overall, the amount of gas you use to get you to your cruising speed (the integral, or "the area under the consumption rate/time curve") is least if you accelerate moderately.

Besides that, you stand less chance of getting run-over by the cars behind you! O.o

[ECHOKnight2000]

I hope this isn't too off topic but where i live (Minnesota) its just under $2.00 US dollars for gas! Imagine that! I thought I never ever see that again! Probably won't last long. I'm sure this will put a damper on Yaris sales...:iono:

My site has a real-world fuel economy survey that is more detailed than most. Results so far:

Real-world fuel economy survey results (http://www.truedelta.com/fuel_economy.php)

Just a couple results for the Yaris so far. Far more for most competitors, such as the Fit and Versa. But I'm just getting started. When I have plenty of results for most models, I'm going to statistically analyze the data to separate out all the variables and get clean city, highway, etc. stats.

[Racer X-8]

Darn, why did I post this question in another thread?...

Why does the Corolla get the nod for best MPG?

[Jem_hadar]

Just filled up yesterday. I got 25 MPG (US) on my last tank.

This tank had absolutely no hwy driving, it was all in-town driving over a 2 week period.

Wow, Im kinda shocked at how weak that last tank was... I wonder if its largely due to cold weather and lots of snow we have recently received?

(I guess usually even with hwy driving clicks on my tanks (often 1/2 or 2/3rds of it) I'm only getting around 29-31 MPG (US) so I shouldnt really be surprised I got 25 on in-town only?)

Your numbers are still way better than those produced with some less fuel efficient cars.
I am just curious. Do you drive short trips very often Jem?

[Carvin'07]

I dunno, that still seems quite low to me. My last tank was 90% city, 90% pedal to the metal, winter tires. Stats below.

33.85 L
444.6 kms
7.613585245 L/100kms

8.931398417gal

[fearturtle44]

Yeah, 25MPG for in town driving is low for the Yaris. Snow and bad weather will definitely hurt the MPG. You might also ensure your tire pressure is correct. And only check when tires are cold and car has not been driven in 2-3 hours.

Kevin

[jgmulligan]

I'm getting about 37 MPG US on my Yaris 2d hatch standard transmission overall. Trip mileage has varied from 34 MPG to 40 MPG. Currently have 3,230 miles on odometer.

Jock

[Racer X-8]

yo there jg, what is that, an average from 8 fill-ups? That's very good, considering the cold-starting conditions. Being in Washington state, I'm assuming you've been getting some wintertime weather lately :smile: .

[swng]

This site can help perform various conversions between metric and imperial/statute units, e.g. liters to gallons and kilometers to miles and vice versa:

http://www.rockymountainmoggers.com/convert.html

The section about fuel consumption is very handy.

[Ah Yum]

My car's lifetime fuel-economy is 6.76 L / 100 km or 34.8 MPG. It's very hard to keep those figures looking somewhat decent in pure city driving. Here's my online log (http://www.greenhybrid.com/compare/mileage/car/4499.html), in which you'll find notes on each tank.

I had another Yaris Sedan - but with the automatic - which yielded 8.01 L / 100 km or 29.3 MPG over the course of six tanks without the mindset for fuel economy. Here's the log (http://www.greenhybrid.com/compare/mileage/car/4504.html) to that car.

[Jem_hadar]

Your numbers are still way better than those produced with some less fuel efficient cars.
I am just curious. Do you drive short trips very often Jem?

Around town? Yes. From home to work, 5-7 mins. Out for lunch, another 5 mins there and back. Home from work.
Then maybe go out to get dinner or a movie.
So in town, yes all very short trips.

But since the summer, I've been traveling to Toronto a lot, about 200 km down the 400 or 404.

To Toronto and back will use something less than a full tank. I also speed on the 400-series highways though. My usually speed is 120km, but I'm often up around 140 or 150, which I figure is what contributes to my avg MPG (US) of about 29 on tanks that do include around 75% or more maybe highway driving.

That last tank where I got 25 MPG was purely small town driving, I'm pretty positive.


Yeah, 25MPG for in town driving is low for the Yaris. Snow and bad weather will definitely hurt the MPG. You might also ensure your tire pressure is correct. And only check when tires are cold and car has not been driven in 2-3 hours.

Kevin

I think I'll check after work to make sure my tires are still at the ideal 32 PSI I think it was. I'm sure, now that you mention it, that they've dropped, since last time I checked was approx a month or more ago, and we didnt have snow then and it was keeping around +5 - +10oC out, instead of the usual now of -20 - -5oC out.

Thx for reminding me to check my pressure w/ the temperatre/weather change.

Jem

[swng]

Thanks for the information Jem! Short trips and any speed above 90 km/hr (+/- something, depending on the type of car) tend to hurt fuel economy a lot, as you obviously already know.
However, I am confident that once you become conscious about fuel economy, you will find/develop ways to improve it.
So, best wishes! Please do post your progress here often.

[spkrman]

31mpg on my last tank... cold start/idling/mildly agressive 50% city driving with the other half spent 70-90 on the highway.

for my driving habits and the conditions, very very happy :)

[Typer73]

My last tank only yielded 31 mpg--worst yet--with trips of 12 miles or less & idling the engine while scraping ice off of that HUGE windshield & both front side windows (and I drive like a maniac on crack).

[mutatio]

31mpg on my first tank with a lot of stop and go city driving and multiple engine starts and stops each day (i drive for my job). maybe 20% highway. i've been eyeballing the tach a bit more on this tank trying to keep it under 3000rpm, 4000 max. the 1st tank got me ~180 miles at the half way mark and right now i'm at 212 miles at the halfway and still doing mostly city driving for the break in period. very nice!

[nsmitchell]

I filled up the other day. 27MPG. It has gotten colder and it was all city driving.

[Jem_hadar]

Yeah, If I'd gotten the VW Rabbit as could have been a very real possibility if I'd been out when I was car shopping at the beg of May, I'm sure my efficiency would have been worse than the last 25MPG I got on my last tank.

yeh, my goal with getting the Yaris was to basically aim high with the fuel estimates. that way, assuming i got less i'd still be heads and shoulders beyond what i was getting in my old car. :)

[Jem_hadar]

or above in another car that you could have gotten instead...

bc, likely, even though you're getting less MPG with your Yaris than what was advertised, you'd also be getting less MPG with any other car too...

nevertheless, overall, your under-performing MPG in the Yaris should still be better than the under-performing MPG of another vehicle (eg. the Rabbit I could have bought, or your old car)

There are lots of factors, check tire preasure, also weather as some effect. If you have any roof rack even if there is nothing on it, it creates drag so that cuts mileage. Give it time and it should get better. Also try not to break as much or hard if possible so keep your car a decent distance between you and the other person and try to keep your speed as consistant as possible. Also short trips where the car is still cold or barely warmed up kills gas mileage, also if you live in a cold place winter takes a told on your car. Just a few pointers! Good luck!

[static808]

wifey just put in her first full tank. with the full tank the dealership gave us, she got 35 mpg on the money according to my gas receipt calculations. much better than i expected, since i dont know whether the dealership truly topped it off, and we did idle for a bit at the beginning, just messing around with stuff inside of the car. havent even checked the tire pressures yet, so im hoping things will just get better. for those who are getting subpar mileage, i hope things get better for you guys too...

the main reason: shifting too high and too much traffic lights/stops. try shifting under 2500rpm and check again the mpg :wink:

[static808]

additonally, short trips within the city (stop n go) absolutely KILL mpg, since the engine is basically running cold the entire time. if this is your driving situation, below average mpg almost cannot be avoided, unfortunately...

Thatd be much of many of my tanks, in small town driving, to and from work, lunch times, trips to the grocery stores or to restaurants for dinner, to friends houses.

all short, 5-10 min trips, and then back again.


Plus, when I do have 75% of tanks based on highway driving, im often speeding at 100km on hwy 26, or 100-140km on the 400 or 404 hwys, so that kills my MPG to.

I guess I just tell myself, well, my MPG may be bad (bc of the way I chose to drive), but if I'd gone w/ another car, it would just be WORSE still.

When i think of it like that, it doesnt bother me

^^ I *think* I got what you're saying (kinda really hard to follow).

You get about 25 MPG on your Yaris in town, but 30 MPG on your Echno in town? And you weren't expecting it to be that low? And arent happy about it?

Is your Echno really getting that much better MPG than your new Yaris.

Now THAT surprises me. (Older) Echos are pulling better MPG than (newer) Yarises?!? :eek:

[Jem_hadar]

Well, just did my MPG for a trip to cottage country.

And it appears I got freakin' 34 MPG ! WOW. I'm happy with that. It was mostly non 400-series hwy driving at around 100 km I think.

Another proof to myself I guess of how much my speed DOES affect my MPG.

The other tank before it was 1/2 in town and the rest was 400 driving, in which i got up to 130 km/h atleast, so it sucked and was 25 MPG.


There's my update for now.

Back down to 31.9 MPG with "regular" driving on this last tank. The previous last two tanks were spent carefully easing my way around town and on the highways sloooowwwly which only gave me 37 MPG tops.

I would like to make a suggestion to those of you, ladies and gentlemen, who regularly post mpg numbers on this thread i.e. consider to mention the post and page numbers of your last mpg report in your every future post about your fuel economy. Please see mine at Post #963, Page 65 for an example. This way it will be easier to keep track of everyone's fuel economy changes. Of course if everyone can report like superjens at Post #977, a few posts above, my suggested method of mpg reporting will not be necessary. However, I cannot expect everyone to do the same. I personally do not have the necessary knowhow. I have my own way though - http://www.gassavers.org/garage/viewgaslog/264.

I'm definitely not going to get good numbers on this tank -- today alone I redlined it three times just to blow off steam. What can I say, I miss accelerating faster than a two legged turtle. :(

Some interesting statistics about the Yaris' fuel economy in the USA here:

[Yaris]

For every 100 kms on my trip odometer, I am pretty certain that my Yaris sips only 7 Liters of gas. When the trip odometer hits the 400, 500 or 600km mark and I am at a gas station filling up, the pump always stops within a multiple of 7 which is either 28, 35 or 42 liters.
You gotta love your little Yaris.:wub:

[CHTHHULHU]

Must be nice. I have just over 5k miles on mine and have never seen better than 28mpg (got that once!). I normally get 26mpg. Maybe something is wrong with mine...

[hystria]

@swng, this is about 33mpg US, considering your city/hw driving, this is similar to about 25mpg US in city driving and 38mpg US on highway driving. Toyota numbers are 35/40mpg (US). It still gets too low for city driving - I experience the same mpg as yours..

[swng]

Most likely it is not your "fault" CHTHHULHU (Post #992).
Previous pages of this thread contain a lot of discussions about why some members get better or worse mpg numbers than the others. If you have time, please enjoy reading them.
I have good reasons to believe that your numbers will improve even if your driving style do not change. Your new car is in the process of breaking in and warmer weather is coming. The most important reason I think is now that you are conscious of your car's fuel economy and once you become so, you will find or derive ways to improve it :smile:.
Please exchange your valuable views and experience with other members on this thread often:smile:.

[hystria]

this is my hope too, that the numbers will get better as the engine will break-in more - actually I believe it's the Oxygen sensor who needs to break-in, in other words to be cooked...

I got 23mpg (US) in normal 100% city driving this fall. Then I tried to shift below 2000rpm and got 30mpg (US) in the same conditions... which is satisfying considering the advertised 35mpg - calculated in almost ideal conditions...

[swng]

Thanks for the comments in Posts #993 and 995. I appreciate the response and dare say I know how you feel. My estimate may not be as "bad" as 25mpg for city driving. I would say about 27-28 intuitively:biggrin:. You know, city driving hurts fuel economy a lot. Especially, when we say city driving, we almost automatically mean a lot of traffic congestions which I think may actually be much worse than what Toyota have in mind (about city driving). I think they are talking about EPA numbers but even those are being/have been/can be reviewed. Please see http://www.gassavers.org/showthread.php?t=2726 and http://www.benzworld.org/forums/w211-e-class/1303380-07-e320-bluetec-epa-fuel-economy.html for some information.
In fact smooth city traffic, albeit bad enough, hurts a lot less than the kind of rush hour city traffic jams that I encounter regularly.
Having said that, I am still hoping to squeeze out some improvements to my numbers, no matter how slight. Admittedly, I have no idea if I can achieve anything at the moment, unless I decide to spend money on modifications. However, the investments involved will be hard to justify from a cost effectiveness point of view:frown:.
Please stay tuned:wink:.

[leowhy]

dear all, really new to this forum...

i'm driving a Yaris 5doors (model 1.5G in my country) auto-transmission...

Had refill the fuel tank for 2 times... & still monitoring on the 3rd refill after the 1st 1000km service...

so far the milage i calculated is about 10.5km/L for 100% city driving... where the low fuel light started to flash...

that's roughly 300++ km for 30L of fuel which i consider high... :(

any advice/comments?

thanks

Welcome to this forum, especially this thread, leowhy!
IMHO, your posted fuel economy is on the low side. Even for 100% city driving, the Yaris should return at least 12 km per liter, if not 14+, if the Toyota supplied numbers are anything to go by i.e. 40/49 per Imperial gallon for city/highway driving in the case of cars with auto transmissions sold in North America. Few people can really achieve such good results though.
Possible reasons for your car's relatively low fuel efficiency that pop up to my mind include that Malaysia is situated in the warmer part of the world and so, you may be using the A/C a lot. Also, it appears to me that your car is still in the process of breaking in. Or can it be that you drive very spiritedly? Driving styles matter a lot! Or do you carry heavy loads on a daily basis or even idle your engine and run short trips very often?
I tend to rule out poor car maintenance or inadequate tire pressure because your car is practically brand new and it has just received the first service. However, you may still like to be watchful over any possible technical problems.
Anyhow, I wish you improvements in the future. I firmly believe that once anybody becomes conscious of the subject of fuel economy, he/she will find methods to improve his/her mpg numbers one way or another. If you are interested, try reading the previous pages of this thread. You will find lots of discussions about how to bring about improvements as well as how to calculate and keep track of a car's fuel economy. Click open those useful links!
Please keep posting your results here. Thank you for your contributions in anticipation!
Safe and happy motoring!

hi, thanks for the warm welcome, replys & suggestions... :)

most of what you mentioned did cross my mind...

refering to weather, i do agree that i need to switch on the aircond everytime i drive... thus contribute to higher FC...

regarding my driving style, well, i'm actually not a "pick-up fan" thus i'm very light on my right foot... haha... i seldom rev the engine pass the 2.5k rpm...

however, i do notice the gear shifting are not really smooth especially from gear1 to 2 to 3 sometimes... even though its an autogear... hmm...

Thanks for the additional information. I will be watching out for your further reports on your car's fuel economy. You may like to mention Post #997 in your next mpg report. With cross referencing, it will be easier for me and other members to form a mind picture about how your car is performing as time goes by.

BTW, this is the 1,000th post of this thread:smile::laugh::biggrin:!!!
