Fuel Economy

[why?]

I'm getting around 38 miles to the U.S. gallon. Half city half highway. I've only put on 550 miles on the car so far though.

That is a good sign.

That is 6.19 l/100km.

[AlphaFox]

Please post if your using Imperial or US MPG #s. The #s on the last 2 pages dont state this so I cant make sense of the readings.

[ricko]

The Yaris was available in Canada a year before the U.S., as a result many of the reports are Litres/100km from the Canadian owners. I think there is a conversion chart somewhere on this thread.

[pennystocks]

My first tank i got 30.5 US mpg w/ mostly city and normal driving. Btw i dont know if its been posted, but http://scangauge.com.
It shows stuff like instant MPG, average MPG, throttle position, battery volts, coolant temp, air intake temp and a couple of more readings.

Its out of stock for now, they say it'll be in may of 06, cant wait to get it, i miss the mpg gauge from my olds aurora 4.0, but anything is better than 16.5 mpg.:thumbup: Also maybe make scangauge.com a sticky?

here is a good converter"http://www.onlineconversion.com/fuel_consumption.htm

And a good calculator:
http://www.vehicleservice.co.za/calc/fuel.html

US MPG is easy to do, so I don't think a calculator is necessary.

Fuel economy was a major factor in deciding to purchase a Yaris. The 2006 Yaris is a NRCAN EnerGuide winner for the most fuel efficient car in the subcompact class:

[jcove]

My latest:

542 kms when I filled up, 37.407 litres of gas in the tank to fill it. Not bad, cause I've had a lead foot lately.... :biggrin:

Have I said before I LOVE THIS CAR. It's so much more fun than most people give it credit for.:biggrin:

nice name there :)

[NickNickNick]

This is kinda unbelievable, but I went 710kms on 37L, mostly highway driving.

That's about 19kms/L, which is awesome...must be about 55mpg? I normally get about 17.8km/L.

That is 5.211267605633803 l/100km, or 45.14 US MPG, or 54.21 Imperial.

Yea, I'd say that is impressive.

[ricko]

What mileage do you have on your car Nick? I have not even come close to that yet.

[El Jefe]

i would post up what my mileage is..but i havent even had to fill up yet! maybe in a few days.
btw how much gas does everyone put in on average? like if it's on the last bar? since it's 11.1 gal tank im guessing 9-10gals on a fill up?

[why?]

We'll see, I'm with you. I've driven 190 miles so far.

[NickNickNick]

What mileage do you have on your car Nick? I have not even come close to that yet

I have about 8200km on my car. I got the oil changed at just over 7000km for the first time, and I check my tire pressure once a week with an expensive digital gauge, making certain the air is always exactly 2.2 BAR. I fill up exclusively at Shell and Co-op stations using 87 octane and my Mastercard, always down/upshift into 2nd gear when turning corners, and I always listen to 100.7FM radio.

If you do the same, you will get the same mileage.

LMAO, that's what's wrong, I don't listen to 100.7. :wink: :thumbup: :headbang: :bellyroll: :laughabove:

[El Jefe]

well i filled up today at 294miles, with 9.9gals = 29.7mpg! sweet and it'll only get better untill it fully breaks in

[Ziv]

huh. 100.7, isn't that the multi-language stations? It have effect on milage????

Bahahahahaahahahahhahaahhaah

[Dylanby]

For those who're getting >= decent mileage:
would you mind adding your $0.02 to the thread on Breaking in a new Yaris (http://www.yarisworld.com/forums/showthread.php?t=425&highlight=break)?

I should be getting mine next week & as it's my 1st new car I'm reading up on best "breaking" habits.

[JaiTomato]

Just bought a sedan a few days ago. So far I have 350 miles and tank is still half.

[Ziv]

Update, half a tank or so,

306 clicks / 23.5 Litre = 7.68 Liters/100clicks.

Mostly city. probably 90/10 city/hwy.

Could Air/Con be that much of a factor? I had it all almost all the time since it's quite hot lately.

In Victoria BC right now at 9:00am its only 54F, but by 3-4pm it'll be around 65F, but Mon, Tue and Wed is forecast to be around 80F, which is about normal for mid May.:thumbup:

Well said, my friend. Not to dis any of our american's Yaris friends. But I believe many of you guys are mislead by the 'Dumb Box'. It's been 20+C for the past week or so here in toronto other than yesterday it rained all day.
And couldn't agree more than most of us who doesn't speak french, other than those who lived in Quebec.

[stuffy]

considering 90% of canada's population lives within 100km of u.s. border, we basically get the same weather that the states do to our immediate south,

anyway, i just filled up and did an average of my last 4 tanks:
5.9L p/100km or
40 mpg
i have noticed that the bottom bars dont' seem to last as long as the top bars, so when i think i am getting totally incredible fuel economy for the first part of the tank, it doesn't end up being quite as good...

but my average for the previous 6 tanks (since new) was 6.7L/100 km or
35 mpg, so there is a definite improvement.

Well considering I have been to Grand Forkes North Dakota a few times one of them being in the middle of winter. I froze my tail off:eek: I think it was 20 below 0 the whole week I was there. Grand Forkes is very very close to Canada for those that don't know.

I'm originally from the Twin cities, MN and lived in Grand Forks, ND for 4 years (1990-1994) I was going to school there at the University of North Dakota ....and it can get REAALLLY cold!!. Back then I was 18, and had a part time job as a Pizza delivery driver. We had to deliver pizzas in BLIZZARDS where you could barely see in front of your windshield, with tempratures hovering around 40 below zero and a 100 below WINDCHILL FACTOR!!! :eek: ....I did have some great times in that city, though. (just got me nostalgic when you mentioned Grand Forks :biggrin: )

Winnipeg is the closest major Canadian city, just about 150 miles north of Grand Forks (the Canadian border is about 75 miles north). Back then I've made the trip up there on a couple of occasions, and in winter it gets just as cold, if not more!!

haha... yeah that sounds right! My buddy graduated from UND also. Thats why I was there visiting him .

I remember seeing my first tumbleweed in Grand Forkes...awwww the memories :bellyroll: I was like "what just rolled across the road?" My friend was cracking up at me.... I felt like I was in the wild wild west. This was during my summer trip out there.

[ubetiam]

this is a cool link i use often

http://www.euronet.nl/users/grantm/frans/fuel.html

[bigsky2]

I have drove 300km so far, and the meter is down 3 bars/levels.

It's currently at 5/8 if you count the # of bars/levels.

Speeds have varied during that 300km. The fastest I went was 110km/h, and average speed is 60km/h.

I upshift at about 3000 to 3200 RPM, and regularly downshift at 2000 RPM.

Most of the mileage so far has been city driving, stop and go situations, and a few clicks on the highway.

A/C has been off for the most part...

[Ziv]

Update--

Man, I hope these number gets better soon.

390 clicks / 30.5 Litre

7.82 l/100 clicks.

[stuffy]

that's not so good ziv, are you driving like a maniac?

[JaiTomato]

Update:
Just bought second tank of gas. Total of 919 miles and 19.8 gallons. That's an average of 46 mpg.
But then that's mostly highway and I drive like someone's grandmother. (Mine never drove a vehicle in her life)

[stuffy]

i've noticed a BIG difference in fuel economy when i take it easy (like a grandma) or when i don't (like ziv)

[Ziv]

Thank you for pointing it out. :iono:
But no, I don't really drive like a maniac. Funny thing is, I have been driving mine for roughly four, five months now. I have NO IDEA why it would behave like that. I used to drive a 2.5 Altima. And I tried really hard to learn to drive a 1.5 like a 1.5. I accelate slowly, let the car pass by me and increase speed like VVTI suppose to be. I hardly go over 3000rpm on local. I drive very little hwy lately because I got everything around where I live.
Even so, city shouldn't be over 7.somethin', should it?

I just got my oil change few days ago. Let's hope it helps! :frown:

I was thinking, if the number stays that way, can you guys suggest something I can do? bring back to dealer for check up? use other octane than just 87?

[bigsky2]

6.9l / 100km is the stated mileage for City driving right?

Ziv, your mileage is almost an entire litre over the stated mileage even with your moderate driving behaviour!

I haven't put gas into mine yet, but I am probably going to use 89 octane.

I'll report back when I fill it up and calculate my actual fuel mileage.

[Ryu]

I got a auto trans yaris, it 9300km on it right now, I do the first oil change at 2000km, second at 5000km, plan to do it at 10000km.
The car is well maintained i assume,
but the best I got is 7.2L/100km which is not that good i guess,
even when the summer time is coming right now, I still got something like 7.4L/100m 0.o

I didn't drive like a maniac also, I guess it is due to the heavy traffic in highway 1 in Vancouver when I go to work. It makes highway driving like a city driving lol.

[foober]

I got 40 miles to the gallon the last fill up. And I'm not driving like an old lady. The car has so much pep to it that i'm having trouble driving slow.

[bigsky2]

Fuel Mileage Stats:

7.33 Litres / 100 KM

Based on the following:

Trip Meter was at 459 KM during fill up
Fill Up Quantity = 33.687 Litres

So after doing the math, it equates to 7.33 Litres for every 100 KM based on that trip.

Most of the driving was city driving, and the usual speed was between 2-3K RPM.

I did go past 3K RPM on a few occasions such as on the highway.

All in all, not too bad considering the stated mileage of 6.9 Litres / 100 KM.

[rob.]

I got 40 mpg driving an auto trans. Combo city (rush hour) and highway miles.

Check your tire pressure...make sure you're running at EXACTLY 2.2BAR/32PSI...makes a huge difference on my car...I had my tire pressure around the 29-30PSI mark, and lost about 10mpg on the highway. I'm sure it'd have been even worse in the city.

It is not necessarily driving like a maniac that can hurt fuel economy.

What are the roads like where you drive?

Do you use the AC a ton?

Do you carry a lot of extra gear?

And of course there is always the chance that something might actually be wrong from the factory.

[ricko]

Ziv ...... you know "Why" might have a point about there being a problem. My mileage has NEVER gone above 6.9L/100km, and my best (in gas miser mode) was 6.1L/100km. I live on the edge of a small resort town, so little traffic to deal with so far, but I have almost no highway miles. For the most part I drive ............ "energetically", because I enjoy the car (Yaris RS 5-speed) so much. I would get it checked out. The only other possibility is that you deal with a lot of "stop and go" traffic. :iono:

[Yaris]

I keep my tire pressure at 37 PSI all around and the car just rolls more easily.

[foober]

I keep my tire pressure at 37 PSI all around and the car just rolls more easily.

I have my tires at 35 psi. I was thinking of putting 37 psi in them. I've heard that can help some.

[punch]

Moving from a turbo charged pt cruiser that uses premium, anything better then 400KM per tank will be a blessing for me.

[Idjiit]

Got 39mpg on my last tank - probably about 80% highway driving (below 75 for the most part).

[pennystocks]

I'm gettin between 29-31 mpg, driving 95% city, 90% of my driving is under 3000 rpm, dunno why its so low mpg. 1800 miles so far on teh car

Also thats like 12.5 km/l or 7.75 for l/100km, i think thats right for 31mpg :/

[punch]

update:

brand new sedan, 370KM on ODO, with 1/2 tank left...

mostly highway driving under 120km/h, with od sprint to 140

[Yaris]

I used to drive a Prius and always drove like a granny to maximize mileage because the stupid display monitor wouldn't let me forget what my current mileage was.
When my lease was over, I went for a Yaris and now drive for the fun of it and not worry what my mileage is compared to other Yaris drivers.
Unless you're a granny, don't drive like one.

[jedi1701]

On my 5 speed 2 door LB I am getting (60 % highway 40 % city) 38 miles to the gal. only have about 400 miles on the car so far. Much better than I thoght I would get.

[JaiTomato]

I just realized that my yaris is getting better mileage than my bike. 44 mpg to 38 mpg

[Yaris]

I have my tires at 35 psi. I was thinking of putting 37 psi in them. I've heard that can help some.

FWIW, I avoid Sunoco gas because of the Ethanol content which contains less energy than 100% gas and always use Shell which is now fully Top Tier (loaded with detergents) to help keep those dang carbon deposits away.

[why?]

From what I have been told, all gas is going to contain ethanol sooner rather than later.

It seems that all the stations around me are putting in ethanol, and one of the employees at one of them mentioned it was a fed thing, not a state thing.

I don't drive enough, lol. My car has about 300 miles on it still.

[foober]

I've got over a 1,000 miles on my yaris now. And just filled it up again today. Getting 40 miles to the gallon now. I keep pinching myself that its doing so well. I'm half highway and half city and I'm not driving like an old lady.

[swng]

Got only 37-38 km out of the 6th fuel gauge bar:frown:. Must have been my worst bar this far. Reasons? Lots of city and up/down hill driving, mostly rather short trips, and the A/C was on most of the time.
Just hope it is not going to adversely affect the overall fuel economy numbers of the whole tank too much. Not looking good anyway because I will probably not be hitting any highway for the rest of the tank.
:cry:.

Thanks a lot. I know they are not very accurate. I just use them as some kind of rough reference. There are certainly better ways to gauge the car's fuel economy, especially for the long term:smile:.

[fearturtle44]

It will be YEARS before ethanol because a reality in majority of cities and towns in the US. People should NOT put any substantial content of ethanol in their current engines. Engines have to be built/configured for a true subtantial ethanol % content.

Personally, I hope ethanol does come sooner but seeing that we (U.S.) did almost nothing for last 30 years (since last gas crunch), I had little faith.

Kevin

[ricko]

My experience is that fuel gauges are never very accurate. The one in my Yaris is very misleading. :thumbdown: It seems safer to use the tripmeter.

Ethanol is a bad thing. A very bad thing. I still haven't found a station near me that hasn't converted to e10. Sad. Ethanol makes gas mileage worse by at least 10%, prolly more, and yet the price reduction is nowhere near 10% of the prices of real gas.

So you and I end up losing money by buying e10 or e15 gas.

I can't seem to find any fed or state law that has been past, so I think the guy was lying to me.

[Ziv]

*Another update thru the long weekend, I actually drove for a lil trip.
402 km / 30.4 Litre
Mostly highway, 80/20 hwy/city
The number still shows 7.56.
When is this nightmare going to end! I am driving constantly at 130km/h in the hwy and hardly going over 3000 rpm in city.*

It is not necessarily driving like a maniac that can hurt fuel economy.

And of course there is always the chance that something might actually be wrong from the factory.

Let's see...
The road is not too bad, for those of us who have drive around richmond hill knows that it's not the best, but it doesn't nearly have as much pot hole than other cities around GTA.

I am cutting down the A/C since the tank before for last, but it doesn't seems to help as much as I would like it to be.

extra gear? not really, the heaviest thing is me. my gf weight probably half or 2/3 weigh than me and my chihuahua, yeah, he's only 6.9 pounds.

I am thinking I will try check the tire pressure as NickNickNick mentioned, and one step at a time.

Ziv ...... you know "Why" might have a point about there being a problem. My mileage has NEVER gone above 6.9L/100km, and my best (in gas miser mode) was 6.1L/100km.

Thank you very much for your input. And yeah, it's true that I deals with TONS of stop and go traffic around GTA.

[why?]

I should have been clearer, not potholes, but are there lots of hills, and do you do lots of stop and go driving? That can hurt mileage.

Of course going 130 kph does hurt gas mileage.

[Ziv]

I should have been clearer, not potholes, but are there lots of hills, and do you do lots of stop and go driving? That can hurt mileage.

No, I don't think there are lots of hills at all. although its call richmond hill, but it's not as bad. I drive an auto and never really downgear to climb. As I mentioned. I never really go over 3000rpm in city. roughly 2500rpm will do the trick bring me around 70ish ~80 km/h.

[why?]

Then it just might be the top speed. The last question is how do you accelerate and decelerate?

Do you use lots of throttle position, and do you find yourself always slamming on the brakes.

[Ziv]

I never floor mine when the lights turns green. My buddy does, he have the RS. And the strange thing is he have the same milage as me.

slamming on the brakes.... not that I notice, although I like turning corners at a higher speed than my old car. I felt I can do MUCH better cornering on my Yaris than my old altima.

As I have said. I will check the tire pressure after work today. 'why?', what PSI do you suggest for tire pressure? mind you, I am still on those 14 stock wheels.

[ricko]

I was once told that to get the best mileage you imagine an egg between you foot and the gas pedal. Lots of scrambled eggs in my car. :headbang:
I really think it is the stop and go stuff. The only time I see that kind of driving up here is on the "Elvis" weekend. :thumbdown:

Do you use lots of throttle position, and do you find yourself always slamming on the brakes.

Yes, yes! A top speed in the region of 130km/hr can mean 15%+ more fuel consumption as compared with travelling at 90km/hr because there is a lot more headwind(=air friction) to overcome. I am stating it conservatively. The difference can in fact be much greater.

[swng]

My experience is that fuel gauges are never very accurate. The one in my Yaris is very misleading. :thumbdown: It seems safer to use the tripmeter.
Thanks a lot for the opinion. For the long term, I fill up the tank, set the trip odometer to zero, drive until the tank is quite empty(but I always try to leave a fuel reserve for about 100km in the tank), then fill up again, and record the trip odometer reading and the amount of fuel bought and then use those figures to calculate the fuel economy of the car. I do the same every time I fill up so that I can know how well my car does in the long term on average.
I believe many friends here use more or less the same method:smile:.

[Ziv]

Yes, yes! A top speed in the region of 130km/hr can mean 15%+ more fuel consumption as compared with travelling at 90km/hr because there is a lot more headwind(=air friction) to overcome. I am stating it conservatively. The difference can in fact be much greater.

My, my. I wil keep that in mind! Thanks!

[why?]

I never floor mine when the lights turns green. My buddy does, he have the RS. And the strange thing is he have the same milage as me.

slamming on the brakes.... not that I notice, although I like turning corners at a higher speed than my old car. I felt I can do MUCH better cornering on my Yaris than my old altima.

As I have said. I will check the tire pressure after work today. 'why?', what PSI do you suggest for tire pressure? mind you, I am still on those 14 stock wheels.

I am pretty sure max tire pressures should be written on the tire. Go by what the tires say, not the manual.

And the higher the better.

[Ziv]

At the side of the car behind the door, it actually mention 32 PSI.

Is higher actually better? because I heard the higher it is, the greater chance of your tire can get bust.

thats the method I use. I'll fill up after about half the bars are gone or 2/3 of the bars are gone. YOu just have to remember to redo the trip meter everytime you fill up.

[NickNickNick]

43.57mpg when I filled today. All city driving - very hard at times.

Good number for all city driving! I guess you must be enjoying some warm weather and there may not be too many hills and traffic lights in your city hehe........You must have done something right anyway! I guess the gas companies won't like you:wink:.

Tires are created to withstand a certain air pressure. This is what is written on the tire.

Go by what is on the tire, not what the car says.

As long as you make sure to keep the pressure within those limits, then the higher up in that range you go, the better it is for gas mileage.

And while too much air pressure is a bad thing, there are rumors of some tires being overinflated too 100 psi, etc, and the tires not having a problem.

In general, if you try to overinflate a tire the air pump will blow long before the tire does.

[punch]

umm how do i do the math, I got 598Km on my first tank, it took 38l to fill it, whats the formula?? 598/ 38= 15.74km/l I then took 100km/15.74 and got 6.35

so if this is correct I got/used 6.35l per 100km, which is close to sticker epa ratings..

Understood. Thanks for the advice, I will just do that.

One really stupid question tho, should all tire pressure to be the same to get best milage?

[Idjiit]

Understood. Thanks for the advice, I will just do that.

No, typically people inflate the front tires between 3-5psi higher.

[Ziv]

No, typically people inflate the front tires between 3-5psi higher.

Really? glad I asked. Then how should I match the tire pressure? if the tire said it's 32 let's say, and should I get the front up to 35ish?

[Idjiit]

Really? glad I asked. Then how should I match the tire pressure? if the tire said it's 32 let's say, and should I get the front up to 35ish?

If you want to follow the "max pressure" guidelines of the tire and the max is 35psi, then set the front to 35psi, and the rears to 32psi or so.

[Ziv]

[Idjiit]

Heh, I think mine are set ridiculously high right now because I didn't let air out after the rallycross I cranked them up for. :O

[Tankota]

Yes you might get some better milage by increasing your tire pressure above the factory recomended settings - but remember you will also increase uneven wear (the centers will wear out before the edges) your braking will be reduced and your corner grip will be reduced - plus the harshness of the ride will be increased... all cause by overinflating the tires.

The numbers on the door are a result of lots of testing with that size tire on that excact style of car - it's the pressure that gives you the best milage along with the best contact patch of rubber on the ground that size tire for that car. Reduce that, and you get less milage, more wear on the edges, and slop and roll on curves. Increase it, yes you might get some milage, but less rubber and control on the ground, harsh ride, and wears the middle. So keep that in mind.. Oh yeah, drive a car with tires inflated to the max in rain? That's just asking for loss of traction in either braking or corning, and even hydroplaning. Those numbers are not just random that they post on the door.

As for the max tire pressure listed on the tire? It's just that, it's the max the tire should ever be inflated under any condtions, it's what it's tested to at the rated speed. Go over that or the speed rating and the tire could fail is what they are saying. Just because your engine is rated for 6500 RPM max before redline does not mean you should drive it there all the time. The most I'd go over the door sticker is 5psi, that might gain you some milage but still have a good contact patch. You can also increase it if you have a heavy load in the car. And it usualy is correct, the front will be higher than the rear due to the engine weight, but if so the door sticker will list a higher number for the front than the rears. Toyota has already paid engineers the money to figure out the correct tire pressure for the car, why go around guessing on your own?

There is some tests you can do to find the right pressure for a modified vehical, I do this all the time with modfied trucks with oversized tires for street use, but the point is on a factory Yaris with the factory sized tires it's all been done for you by experts, listen to it.

[Jem_hadar]

No, I don't think there are lots of hills at all. although its call richmond hill, but it's not as bad.

TRUEEEEEEEEEEEe.

I was just there on Monday around 1030am dropping off a friend on my way from TO back to Collingwood.

And yea, RH, not many hills... now fucking NEWMARKET!! THat's a WHOLE bloody OTHER story! Egad! LOL :laughabove: :laughabove: :laughabove:

Newmarkt is BRUTAL for stick IMO!!!

[nwdixieboy]

I got 42.5 MPG in pure highway mileage. I live in Seattle with lots of hills and get anywhere from 25 to 32 in mostly city driving.

[stuffy]

the best i have acheived is 40 mpg on average, and that is driving very easy 50/50 highway/city, tire pressure is checked every 2 weeks

i don't understand how some can get better mileage in the city, driving hard,

are some of us not doing the math properly or can there be that much variation with the same car?

Thank you very much for the detailed info. It's not like I am guessing what would be best for tire pressure to ensure best milage. I just think it would be nice for those of us who share the same car with their own opinion of what they think would be better. Afterall, this is the first car I truly brought myself. I would go anything close to factory made anyways, i think, unless I know more about it, I wouldn't go crazy and pump 10psi over. hehe

[spellcheck]

Thought I'd add this report:
Yaris sedan - automatic
For a 166 mile stretch of highway (I86 through New York State, so quite hilly), I used 3.76 gallons, which is about:

44.1 mpg
(or 5.32L per 100km).

Most of it was at 70mph except for a 20 mile stretch of construction at 50mph. I had the air conditioner on for only a couple of minutes. The trunk was full.

I'm pretty impressed by this little car (assuming I calculated everything correctly, and the trip meter and gas pumps were all functioning properly). I'll have to measure it again on my next trip and see if it compares.

You guys got some ridiculus numbers. When is it going to be MY TURN!

well in my case it was the first tank, I drove slow, never going above 130km/hr

on my current/secound tank, i'm just driving normal without looking at the gas uasage, and i can see its burning it faster, but i also have driven at 140 too...

will post the results of my secound tank when it runs empty..

[NickNickNick]

My last highway trip I drove 710kms on 38-39 litres.

My last city fill was 31L on 478kms.

I will say that I live in Saskatchewan, and there are virtually NO hills at all, though the highways are crappy enough that there is a lot of slowing and accelerating on the highway.

Toyota engineers are recommending settings for 1 thing only - safety. They have to assume everyone that drives the car shouldn't really have a license, so they have to make all settings super-conservative so that the morons don't kill themselves and Toyota doesn't get sued.

No one ever recommended over-inflating tires.

Tire manufacturers know more about their tires than Toyota does. They know what is safe, and what the tires will handle.

Using the maximum pressure of a tire will not cause uneven tire wear as the manufacturers have created the tires to run at that setting.

It is always best to trust the manufacturers of a component over the manufacturer of the entire car.

[bigsky2]

Update:

Second fill up on 89 Octane.

Results:
7.19 Litres per 100KM

[Idjiit]

This really isn't true. Tires don't exist purely outside the context of the car they're attached to. The performance characteristics of the same tire attached to a 2,000lb car vs. a 4,000 lb car are going to be different. You cannot simply say "the max tire pressure is 44lbs, so that's what I'm going to use". It just doesn't work like that.

[foober]

another thing to take into account. Is the gas stations you fill at. I just filled half my tank and found I am now only getting 36 miles to the gallon. My last three half fillups came out to 40 miles to the gallon at another gas station. Then I went to this other gas station and wound up after the calculations of getting the 36 miles to the gallon. Could it be that gas station meters out gas differently.

Yes, this is the fundamental flaw in the self-calculation method. Depending on the pump, how far you have it stuck in, etc. the amount of gas dispensed on a fill up can vary.

[swng]

Seems you have a reason to suspect foober. On the other hand, the meters are checked regularly, if I remember what I have read from elsewhere correctly. Too many factors influence our calulation results and that is why I suggest to record our numbers for the long term so that a more reliable average can be worked out.
I have not done well with my latest tank either. It yielded only about 37.3 mpg(imp) or roughly 31 mpg(US). That must have been one of my not-so-good tanks. There have been many short trips in the city and the A/C was on for a number of times.
Thanks for sharing your numbers.

[swng]

Yes, this is the fundamental flaw in the self-calculation method. Depending on the pump, how far you have it stuck in, etc. the amount of gas dispensed on a fill up can vary.
Valid observation! Thanks! Hopefully long term average numbers can somehow compensate for the errors resulting from the variations that we cannot control each time we do the calculation after a fill-up.

[why?]

Pumps must dispense the correct amount. They are all checked.

However different brands of gas can give different results. That is why it is good to find a gas that gives results you like and stick with it.

My first 2 fill ups, finally:

1st to make sure the tank was fill from the dealership: 19 miles, .688 gallons = 27.62 mpg.

2nd one today, 460.2 miles, 10.85 gallons = 42.41 mpg.

Total so far = 41.53 MPG.

That equals 5.66 l\100 km or 49.88 mpg Imp.

[swng]

My, my. I wil keep that in mind! Thanks!
Hi Ziv, on this page, you will find some information about what we have been talking about i.e. the higher is the speed above the car's optimal speed, the higher is the fuel consumption rate:

www.fueleconomy.gov/feg/driveHabits.shtml

Hope you like it.

Edit: After reading the Driving More Efficiently page, please also go to the Gas Mileage Tips page (click on the left near the top of the Driving More Efficiently page) and watch the MotorWeek video. It is very relevant and very good! Enjoy!

[Idjiit]

Pumps must dispense the correct amount. They are all checked.

I didn't say that pumps won't dispense the "correct" amount. I'm saying that the sensors in the pumps in conjunction with how you use it (and environmental conditions) will vary how much is able to be dispensed. The self-calculation method hinges on the idea that you're getting a "full" fill-up every time. These variances can lead to miscalculations.

[stuffy]

yeah, you have to average over a number of tanks to get an accurate idea of your fuel consumption, this will factor in the varying driving styles and conditions as well.

[markpeppie]

car went to 500 km before i had to fill it up, cost me 39 $ at 110 , i'am amazed

Congratulations on the apparently good numbers! Hope better and better results keep on coming to you. Here is a site you can use to calculate the mpg numbers of your new car. Enjoy:

[Sp33dY]

Heres a good one for kms/L - http://www.hicloneqld.com/data.htm
I did 595kms off this tank and use 41L. 6.9L / 100kms!

[swng]

Nice! Just added it to my list of favorite sites.

[bigbull]

I have just filled up for the second time and have hit 1260 Km, I got the car with 19 km on it. Considering I cam from a 1989 Jeep Cherokee that had a 60 L tank thai I filled up 1.5 times a week I am in heaven! So far these numbers seem to compare to what everyone else is getting.

[Ziv]

Update:

442 km / 32 Litre
Roughly at 7.24
went up again, but at least is not around the 7.5 again anymore. Hope it does goes under 7 again next fill.

[David81]

I got my yaris 2007 sedan aero package today. Gas i'm not sure yet, didin't get to use a full tank. But i got it today, drove 79km and didn't even lose a bar of gas. Well it still reads full gas.

[swng]

All bars do not represent the same amount of fuel. I bet you can easily get way more than a hundred km with your first bar. Other bars do not last that long however.
Enjoy your new car!

[NickNickNick]

Filled today.
37mpg in-city over 348km...

It seems the further I go without filling, the better mileage I get.

When I didn't fill for over 650km, I only got 37L in, and was getting over 40mpg in-city. Does anyone know if this could happen?

Plus: A good metric calc.
http://www.roity.com/petrol/metcalc.html

[swng]

Sorry, not really have an answer for you because the difference you have achieved seems big. It may be a good thing to know such a way of getting good fuel economy though. Just hope that it is repeatable. Frankly, and I think you have implied it too, this seems to run against common sense.
However, if you fill up often, you carry a full tank load of gas often. If you travel with a half/near empty tank, you carry less load.
There are enough reasons not to drive with a near empty tank, but the fact is doing this saves you a little fuel. Just a little, hehe.............
Just added the site you recommended to my list of favorite sites. Thanks!

[Adriaan]

hey guys back from another trip from toronto, full my tank to the max in montreral. avg speed was about 140km with a/c on the whole trip ,3 adults and alot of bags, Did montreal to mississauga in about 5 hours then drove back to ajax did about 620km starting to get worried the last bar was flashing since about 575km. my car is manual. good air pressure 35psi in about 25 degress heat for the whole trip. when i fulled up the second time the car took 40 liters.

[Leenis24]

Still have just over half a tank left from full tank, and i've driven about 190 miles so far. Thats about 38MPG if i've only used 5 gallons on the 11.1 gallon tank. These are all just measurments from my best analysis. Its still on the first tank of gas, i got the car yesterday. I'll do another calculation when i refill the tank to find out how much i used from the first full tank.

[swng]

hey guys back from another trip from toronto, full my tank to the max in montreral. avg speed was about 140km with a/c on the whole trip ,3 adults and alot of bags, Did montreal to mississauga in about 5 hours then drove back to ajax did about 620km starting to get worried the last bar was flashing since about 575km. my car is manual. good air pressure 35psi in about 25 degress heat for the whole trip. when i fulled up the second time the car took 40 liters.
That's roughly 43.7 mpg(imp). That's good considering the load, the A/C, and the speed.
I have noticed that the last bar will flash faster as the fuel tank gets closer to emptiness. When it happens, I would drive to the nearest gas station without more hesitation.

[fearturtle44]

I got 39 mpg on my first full tank of gas. About 50/50 on city/highway driving. I was IMPRESSED....

[swng]

Please prepare to be more impressed later, as your engine breaks in :wink:.

More and more fellow members have already gotten or will soon be getting their new cars. For the benefit of all, would the new car owners please post their fuel economy here? The bigger the sample base, the better.
All are welcome to share their fuel saving tricks here too!

[JaiTomato]

Here's an update. I've driven 2623 miles and bought 60.012 gallons (6 fill-ups). So that's an avg of 43.7 mpg.

[Ziv]

Update:

I break it under 7 again! yaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahooo.
460 clicks/32 Litres
40.625mpg
** 6.956521 L/100 clicks. **

To all new Yaris drivers, I used to be just like some of you, always near 7.5 or so. But for me, after the first oil change and over 9K-somethin' clicks, it's looking all good from here. =)

[swng]

:clap: :clap: :clap:
I also had an oil change just a while ago. I will post my results soon.
The tank is still half full now. Will see if the oil change can really help.

[jay]

Yet more data (FWIW)...

Closing in on 10 000km. I continue to see a general trending downward in fuel consumption, lifetime avg consumption now sits at 6.92L/100km. Data from last 4 tanks:

6.88L/100km
6.05L/100km (lowest yet :thumbsup:)
6.24L/100km
6.13L/100km

... under these conditions:
- 70% hwy/30% city
- 10% ethanol fuel
- AT
- some A/C use in recent weeks
- 100km/h-105km/h hwy cruising speed
- tire pressure = 240kPa (35psi)

I find the current numbers (in the low 6s) quite acceptable :smile: (down from low 7s during the winter). At this point, I wouldn't be surprised if the numbers have bottomed out for me, as the peak summer months are just ahead (i.e. more frequent A/C usage), and I don't know how much more a factor mechanical wear-in will play. I'd be cool, though, to break into the 5s.

Owned my car a little over a month...5th tank of gas I believe. Put on approximately 350 miles a week. So far, just averaging 32 mpg...hope it get's better! About 1/2 city 1/2 highway. Up and down 1,500 ft. elevation daily.

That should be equal to about 38.4 mpg imperial, presuming that you are posting your mpg as miles per US gallon. That's quite close to the average I have in mind. Considering that your car is still new and the elevation could have adversely affected your car's performance slightly (fuel burning is likely to be less complete on high altitude), I would say that your results are not bad. Keep on posting your numbers please.

[Idjiit]

So, with a fully loaded Yaris (two people, two medium sized dogs and all my photo equipment - printers, a couple computers, monitors, etc.) we got 41MPG over a 400 mile trip going between about 70-80mph. Even with a margin of error in there, we're extremely happy.

[redglare45]

Hey guys, here's how I'm doing: Filled up yesterday and put in 10.8 gallons, pretty close to our 11.1 gallon tank huh. Before the fill up I had gotten 368 miles, so it seems that I'm getting 34.07 miles per gallon. I've done mostly city driving, so I guess that's not bad. :wink:

[fearturtle44]

Yeah, 34mpg sounds right with mostly city driving. I got 39mpg with 60/40 highway/city driving. I am extremely happy with the mpg as well as the comfortable ride.

[Ziv]

Update:

450 Clicks / 33 Litre
7.33 km/100 or 38.5 mpg.

Mostly cities and I think the numbers is staying pretty well lately, all near low 7 and high 6s. hehe.

[adnanmalik]

I have got Yaris 2001 and my car has given me 570km in 38 litre

[swng]

I have got Yaris 2001 and my car has given me 570km in 38 litre
Thanks for reporting your numbers. They are not bad considering that your A/C must have been on all the time :wink:.
By the way, do you find your A/C powerful enough?

[Ryu]

I've been filled up the tank of my Yaris so many times,
The best of all is only 7.1 something L/100km, average before is like 7.2L/100km or 7.3L/100km.

Today.... I am so shocked, when I go fill up I used up 15.11L for 218.2km, which is 6.92L/100km, i am so happy that it can finally go below 7.0, one big step for me :laugh:

[Ziv]

Like I said before, once I have hit a high 6, I have never hit mid 7 anymore. Hope best for you is still to come.

[Ryu]

Thx man, I forgot to mentioned it got about 10500 kms on it now.
I guess the fuel consupmtion of this car really getting better and better once it is fully break in

[stuffy]

i just filled up today after conducting an experiment, for this tank i really pushed it, fast starts from a stop, pedal down for the whole tank,on the highway i was up to 130 km/h (fast for me) and the mileage i got was 7.2L/100km or 33 mpg (us).
so this was a noticable difference from driving like a grandma, i was up to 40 mpg.
i think driving style is a huge factor.

[Ziv]

Thanks stuffy, heads up for all of us!

[stuffy]

no problem, it wasn't a very expensive experiment, and i have to admit, it was enjoyable.

[fearturtle44]

Not sure if I would suggest such a drastic engine experiment on a very new engine. But then it is a Toyota!!!

Kevin

[stuffy]

mine has 7700km on it, so it isn't too new

[foober]

Thanks stuffy for doing that experiment. I would think that fast starts and running the engine hard would eat up more gas. My little lift back yaris has so much pep to it I'm having a hard time not going faster than any other car on the road. I'm really amazed how much zip my yaris has. It loves to cruise at 80 miles an hour on the highway. And i'm always having to try and slow down. The liftback just wants to go fast. And I'm still getting 38+ miles to the gallon. I really want to trade my toyota tacoma truck in and get another yaris but I really need a truck.

[stuffy]

yeah, i had beenconsciously taking it easy up to this point because i wanted to see how good the fuel economy could be, but i also wanted to see what happens to the fuel economy when you push it a bit.
i'm sure evereyone here has different driving styles, and with such wildly different fuel economy reports, i wanted to see for myself.

[ECHOKnight2000]

I have a question regarding a/c, yes I know it eats at your gas milage especially if your going up hill on a hot day, but I usually don't use my a/c, only if really needed then I turn it off, anyway since I don't use it, I usually just turn the dial to cold and have the air flow come from the out side, like the vent symbol and the symbol for when the air comes from beneth the dash? Know what I talking about? Its the setting where air comes out of the vents on either side of the cabin but not the middle ones (at least not as strong-hope that made sense) Even if the day is "warm" at least not above 80, it gets fairly cold or at least keeps me cool but I didn't push in my a/c button, I'm I still eating away at gas but not as much if I had my a/c button on? I assume obviously the condenser or whatever is still working just not extra hard cause the a/c is not on, but I don't know the technicalities of it, any help or anwser would be appreciated.:smile:

[NickNickNick]

Update:

608km on 36.5L. All city driving.

6.0L/100km

[swng]

Here is my update:

628 km for 42.929 liters. That is 14.63 km per liter, or
41.348 mpg Imperial, or
34.45 mpg US, or
6.835 liters per 100/km.

The A/C was on many times and the time ratio between city and highway driving has been about 35/65%.
Warm weather helps.

[Ryu]

Swng, the fuel capacity for the yaris is 42Litres, isn't it? :eek:

[bigsky2]

Another Update:

525.2 km on 37.479 Litres

Works out to be 7.13 Litres / 100 km

Notes:
- 89 Octane (Canada Rating)
- All city driving
- MT
- I usually shift at 2800 to 3000 RPM (see note below hehe)
- Was pushing the engine hard 40% of the time (shifting at 4500 RPM)

Well actually, I think that's the only way to get a/c without push the a/c button. Its to turn the nob pointing to 'air out to dash'. I am sure that is using a/c because its a heck lot cooler. so instead, might as well use the a/c so it points directly to ya. ha ha.

[swng]

Swng, the fuel capacity for the yaris is 42Litres, isn't it? :eek:
Yes, officially it is 42 litres. However, if you fill up your tank until it almost spills, you will be able to squeeze in more than that amount, presuming that you start with an almost empty tank. Frankly, I do not recommend that you do so. I do that just to improve the accuracy of my mpg calculations.
Some previous pages of this thread contain more discussions on this subject.
Thanks for your interest Ryu!

[Ryu]

Thanks for your explanation Swng, then that make sense.

However, I go fill up after 1 bar is gone cuz of the cheaper gas price,
and it turns out 9.621L for 143.2km, which is 6.718L/100km.
I thought the car will stay around 7.3L/100km forever cuz of about 10 fill up after I got the car. I just got 6.92L/100km last fill, it seems getting better and better now.

This car is full of surprise :biggrin:

Thanks for your anwser...but you are right about staying cool without pushing the button, if I flip the lever so the air circulates within the cabin it starts to get warm but when I flip it to circulate air from the outside it cools down. Thanks again.:thumbsup:

[Ziv]

Update:

Number one, it was all cities. Two, I blasted my a/c like there is no tomorrow lately, it's been 33+ as of late. Even during the night is pretty hot.

[fearturtle44]

Selecting the fresh air setting only brings in the outside air. So if it is 95 degrees outside, then this setting will NOT do any good. Only the AC button will help. However, on those cool morning or cool evenings, the fresh air setting might be all that is needed.

Kevin

[swng]

If you wish to rely solely or heavily on the "cool" air from outside, please consider buying a sun shade to prevent the sun from shining directly into your car while it is parked. Even the most expensive types should be quite affordable and they are effective. In the long run, because of the resultant reduction of the A/C's workload and hence improvement in fuel economy, the sun shade will pay for itself.

[spacemanoeuvres]

Just filled up for the first time on Saturday.

Liftback took 11.009 gallons with the odometer on 395.

That's approx 35.9 (US) miles per gallon...meh, not great

Driving was 65/35 highway/city and I had the AC running about 65-75% of the city miles.

The car seems to do much better with the AC off.

You are totally right on that...especially when its like 90 and above or even 80 but in my experience any day below 80 degrees, even with the fresh air setting, it gets pretty cool and I'm surprised as this is from the out side air as you were explaining so:iono: :iono: Sure it may take a little longer to cool than a/c but overall it works, maybe most people won't be satisfied with it but I'm skinny and I'm pretty much a passive person generally speaking so I don't mind as long as I'm comfterable-each to his/her own. If I put on the circulation for internal only, and not coming from the outside it starts to get "warm" but if I switch it back it "cools" the cabin down, so I'm not complaining. Even summer evenings it cools down pretty nicely.

Couldn't agree more and I believe this is a cheap effective idea. Even if you have tinted your side windows, you could not tint your front dash windows, so a sun shade would be kick in nicely.

[why?]

Just filled up again. Went 447 miles and used 10.106 gallons of gas. That is 44.23 mpg US.

That is 5.32 liters/100 km.

Since I've had the car, I've driven 932 miles and used 21.64 gallons of gas. That is 43.07 mpg US and 5.46 liters/100 km.

I can tell my car is finally starting to loosen up a bit. I hope the increase in gas mileage continues.

[Ziv]

5.32, that is insane!

Wow! That's amazing! And your not even at the 1000k mark...very nice:thumbup: I guess cars vary when it comes to "break-in" times, some take awhile and some don't:iono: So what's your driving style? Obviously stay within the speed limit? Lower than it? Mostly city, highway, both? I know I can look up how to "conserve" gas and what not but real world figures or personal testimonies are always interesting and informative, obviously it will vary from car to car and enviroment and driving style, just curious. :smile:

[foober]

why, did you drive alot of highway miles to get that good milage. That is really good. I'm getting about 38 miles to the gallon. But I'm driving fast and doing half city driving and half highway. I've got 1,700 miles on my little yaris now. Love that car.

[why?]

I don't actually drive very much. I go from my home to the nearest center and back, and that is about it. The last time I filled up my car before yesterday was 5/27, lol.

I don't know the exact percentage of highway driving, but I do very little stop and go city like driving.

It might be 50/50 highway at most, and my average highway speed isn't very fast. The limit is 55, and I usually get it up to 60 and let the car coast down to 50.

I'm light on the gas and the brake, and I avoid accelerating up hills whenever possible, even though the area I live in is rather hilly.

Thanks for the response...you mentioned you go somewhere close to you? I thought short trips effect gas milage cause the engine doens't have time to warm up and get to "normal" operating temp but hey there are exceptions. With me my part-time job is 10 min 15 min tops and my car warms up but I'm sure it doesn't warm up to full "normal" operating temp as I'm not travelling far, I'm sure that it effects my milage. Oh well!:rolleyes:

lol, will do.

[fearturtle44]

The "cool" light will go off depending on outside temp. If the o/s temp is 90 degrees then it will go off fast as the engine will get to warm very fast. If the o/s temp is 20 degrees, then expect that light to take longer. Correct??

Kevin

[asa805]

I dont know how so many people are getting such good mpg! I did only one fillup thus far (with A/C on for most of the miles and no trips more than 15 minutes) and id say with 90% city driving i avg. 27 MPG!!!

This sucks and im pretty dissapointed in it. I know i drive in NYC and apparently it is an ethanol blend city, so perhaps that is why.

Should i expect to see improvement since the car is not broken in yet?

Sorry to hear about your gas milage, it should improve over time as the car breaks in, also I think since you are in NYC, the biggest city in the U.S. might have an effect on it, obviously any city driving is going to yield lower milage. I heard ethanol lowers milage but from what I read the Yaris doesn't take enough to effect it meaning 15%n ethanol or so shouldn't effect milage too much if at all. Hope it goes up, keep us posted!

fearturtle44-you are correct, outside temp does effect how fast the engine will warm up (and when the light will go off), of course if you race it cold that will speed it up during the colder months (where ever that applies) but obviously you shouldn't and I don't advise "racing" a cold engine if possible. But from what I observed it warms up faster in the summer than winter which is a major give-in-what I also observed even if your driving on a 70 degree or so day, and you take a short trip, and the blue light goes off and you park for 30 min or so and get back in the car and leave the light will come back on as you haven't driven far enough to fully warm it up, but will go off right away or sooner than you first drove cause the engine has already been up to an operating temp for the light to go off and time of day effects it too. The light goes off when the engine reaches a certain operating temp which is not an optimized operating temp (as explained above in the example)-yes it gets to there but I'm saying when it goes off doesn't mean its at its full opperating temp yet...if that makes sense.
Enough of my babble. :cool:

Ethanol will lower gas mileage by the same percentage of ethanol that is in the fuel. If it is 10%, it will lower your gas mileage by 10%.

MA just switched to a summer blend with 10% ethanol. Pathetic morons in the state house don't have a clue.

[Idjiit]

Jesus. Where do you get this shit, dude? You're telling me that a Yaris running E85 would get 6mpg? The reality is that most FFVs running E85 get about 30% less mileage, while the new improved models only see about 10% less mileage.

[why?]

How about with experience? Duh.

The 10% ethanol crap that we are using in MA has lowered the gas mileage on the other cars I see by 10%.

The Yaris is not an FFV, neither are the majority of vehicles on the American roads today.

Ethanol is basically water, not exactly something that will be good for gas mileage.

[Idjiit]

How about with experience? Duh.

How about actually having facts instead ridiculous assumptions based on limited data?

The 10% ethanol crap that we are using in MA has lowered the gas mileage on the other cars I see by 10%.

So that means that can be extrapolated to a general rule about all ethanol products? Dude, seriously, get a grip. You're not this stupid.

[why?]

But you obviously have never used your brain. Of course, you are a liberal so I shouldn't be that surprised.

Every amount of data is limited. No one human can possibly know everything. However, as a car guy, I know a lot of people who drive a lot of different cars, and SURPRISE, when I am around we talk about, oh, can you guess it, That's right, CARS!!!

Now because of the absurd price of gas, almost all the talk circles around, oh wait, can your liberal addled brain guess what we talk about, could it possible be, gas mileage?

You bet your ass it is. Even the dude with a 500+hp mustang is worried about gas mileage. And no one I have encountered has said their gas mileage has gone up. Not 1.

This means ethanol is worthless. It has no place in fuel.

Of all the people I've talked to, the majority have seen losses around 10% when MA forced ethanol onto us.

Now you can be a liberal and go on feelings alone, however people with brains tend to use them. And when everyone is saying the same thing, a conclusion is made.

That conclusion is that ethanol simply does not belong in gas.

[stuffy]

drop the liberal bashing why?, it just points to your pathetic insecurities.

ethanol is not as effecient as 100% gasoline, so naturally, you wouldn't get as good mileage as 100% gasoline,
i read an article in the paper that stated this, and they were making the point that ethanol is not all it is cracked up to be.

[fnkngrv]

wow i expected alot more if it is only that much mpg (32ish american mpg) ill start heading back to the xb... by the way what rpms are you revving when your at 80 mph


I know this goes back to the beginning of the thread, but if I didn't miss something I can answer this. I bought my S in Mankato, Minnesota and drove it home to Maine. I was usually cruising around 75-80mph (this was right around 3500 rpm) on the trip home and was able to achieve 446 miles right before the final eight of a tank began to blink. I was able to pull into a gas station 6 miles later and filled up. I put in 10.1 gallons for the first tank that I had. Do the math and that is 44.15mpg! I was amazed since the quoted I has seen was at 40 highway not to mention that I had the A/C max kicked ont he dial with the fan at 3. I have now placed around 2600 miles on my Yaris and have a total average over the "life" thus far at 39.6mpg. I drive 11 miles each way to work and my in town driving nets me around 5-12 miles a day. All in all very impressed. I did notice that I do get a couple more miles to the gallon if I use a/c rather than have the windows down.:w00t:

[fearturtle44]

Keeping your windows down will put drag on the car and thus poorer MPG than running your A/C.

Kevin

[Idjiit]

But you obviously have never used your brain. Of course, you are a liberal so I shouldn't be that surprised.

This is the lamest ad hominem I've ever heard. The simple fact is that you were talking out of your ass about how the percentage of ethanol relates to mileage. You're wrong. Just like you were wrong about how everyone should run their tires at the max pressure marked on the tire. I'm not even going to address the rest of your pathetic diatribe until you acknowledge that.

Being wrong isn't necessarily bad, but not being able to own up to it gracefully is.

[why?]

Of course I'm right, and you're too dumb to acknowledge it.

[Idjiit]

Of course I'm right, and you're too dumb to acknowledge it.

Dude, you can't honestly think I'm dumb. Why don't you just drop the ad hominem bullshit and debate me like the intelligent person you clearly think you are?

Anyway, so you stand by the claim that a vehicle (a FFV, I would assume) using E85 would get 85% worse gas mileage than a gasoline counterpart? So for instance a bespoke FFV Yaris would get 6mpg on E85 instead of 40mpg? This would match your claim that a car sees a reduction in mileage equivalent to the percentage of ethanol in the fuel.

[stuffy]

according to that argument, ethanol is then basically just a filler with no fuel properties whatsoever.
i think in the article that i read, it stated that ethanol was 80% as effecient as gasoline.

[YarisBueller]

Ok fellas, keep the thread ontopic. NO NAME CALLING. NO REASON TO BASH EACH OTHER, we are all in this together. Pleae keep the thread clean. Thanks everyone!

[spacemanoeuvres]

Keeping your windows down will put drag on the car and thus poorer MPG than running your A/C.

Is this true?!?!?

I know the additional drag doesn't help but is it really worse than running the AC?

[ECHOKnight2000]

Is this true?!?!?

I know the additional drag doesn't help but is it really worse than running the AC?


It is worse than AC at higher speeds like highway, personally I only roll my windows down if I'm going 45mph or lower yeah sometimes I go above but I personally make it a point to only have them both down or one down when I'm below 50mph...because the lower the speed the lower the drag...there's drag no matter what speed you go but obviously as stated before the higher speed you go the more drag...I see (during the summer) plenty of people on the highway driving 65-70+mph with there windows down...I shake my head only if I can pull them over and show them the light:biggrin: Enough of my novel you get the point:thumbsup:

[fearturtle44]

A good analogy is NASCAR where cars try to draft in order to conserve gas but stay at top speed.

I have the 5 spoke S model 15s and let me tell ya....I honestly think that they look too small....might.....just might.....look aight if you dropped the car 2 inches, but at stock height...small.

[stuffy]

how does aftermarket rims affect gas mileage generally?


i imagine there would be some small improvements depending on how much lighter the wheels are compared to the stock steel wheels.

[Ron]

stock 14" steel wheels and the 175/65/14 tires weigh ~30lbs per corner... its not easy to get lighter than that without spending a lot of money.

my fuel economy has probably gone down ~20km/tank with fatter tires, heavier wheel/tire setup. time will tell, as i drive them some more and do more fillups

[spacemanoeuvres]

Fill up #3:

Took 11.350 gallons with the odometer on 398.

That's approx 35.1 (US) miles per gallon...blech, disappointing :thumbdown:

Driving was 65/35 highway; frequently cruising at 80+ mph with the AC running about 20% of the city & hwy miles.

[foober]

My gas milage has gone down as well at 2000 miles on the car. Last fill up was 37 miles to the gallon. But I'm running the ac full time now. I've been doing alot of city driving as well.

[Chris07LB]

Current tank, 375 miles, with two fuel bars left. I have been getting over 400 miles out of every tank so far.

I drive at 70mph, for about and hour or so straight. I see only about 5 miles of city driving, once getting off the highway.

3 weeks old today, automatic / Liftback. :smile:

I found a product which has a lot of backup and testing and claims pretty fair fuel economy and performance for little money.

http://www.ecotekplc.com/

I am going to buy one at some point to try it.

[Tankota]

Consumer reports tested a ton of products like that, as well as a few other reports.. then did not find a single device or additive that improved anything, and in fact some of them made things worse. Don't belive everything on the internet.. :biggrin:

As they pointed out, if there was an additive that could improve your milage or power like they claim, gas compainies would have added it long time ago.. just think - if one brand gas gave you more milage than another brand, they would be marketing and selling it like crazy, and people would buy it over another brand (and it wouldn't realy cost huge gas comanies anything to add the same stuff thats sold aftermarket).

[ECHOKnight2000]

Going along with what Tankota said, not only is it really a scam and if it did work others would jump on board namely the oil companies...also since gas has risen and its an "issue" at least in the U.S. cause we're spoiled brats but anyway you want to be weary about these things as I'm sure they will bank on our mentality of saving gas and doing whatever it takes including being desperate about it. I'm sure this is open season for these kinds of products since gas has risen, and you have to study or look at how they word things as well...like implying their product boosts a great deal amount when it might not...anyway you get the point.

[swng]

If so, I would wait until something gets some positive comments of Consumer Reports before I buy. Meanwhile, it would be useful if anyone who has been using such devices post his/her fuel economy numbers here.

[boxerboy]

First tank was 9.85 gals. 375 miles. 60% highway,AC on. 5spd hatch.

[swng]

My last tank has yielded 588.8 km out of 41.067 liters. This translates to approximately :
14.338 km/liter, or
6.975 liters/100 km, or
40.519 miles/gallon (Imp), or
33.766 miles/gallon (US).
The time ratio between city and highway driving was about 40/60 and the AC was on more than half of the time. Tire pressure - 34 psi all around.
Not bad for an auto :smile:.

last tank was on one flashing bar with 655 km so i havent been botherd calculating it but i am pretty happy with it :D

I like how you think you are going to get 40mpg driving 25+ mph faster than how the EPA rates it.

Glad you like it :thumbsup:

Seriously though, I was expecting a consistent 36/37 mpg out of the Yaris. Especially since my 93' Paseo (rated at 28/34) used to get 35/36 mpg driving exactly the same route/speeds.

I don't think that's unreasonable :iono:

I think the paseo is much more aerodynamic than the Yaris. It definitely looks more aerodynamic than the liftback.

Also gearing could come into play. But I think you would have closer numbers to what you expected if you had got the Yaris Sedan. The Paseo and the liftback are way different body designs.

The Yaris Liftback is 9 inches taller than my old Paseo so the aerodynamics definitely come into play, especially at higher speeds.

Once I save up a few bills I'm going to hookup the lowering springs so that should help.

Fill up #3:

Took 11.350 gallons with the odometer on 398.

That's approx 35.1 (US) miles per gallon...blech, disappointing :thumbdown:

The car's hardly broken in, you need to relax. After the tires break in a bit, you'll see an increase in mileage, and keeping your top speed around 70-75mph will help tremendously. There's a steep fall off in MPG over 70 in our Prius even.

[NickNickNick]

Last fill: 650km on 36L.

42mpg USA. 5.5L/100km.

[Ryu]

Another fill up for the automatic Yaris 332.1km using 21.843L
comes to 6.577L/100km

[swng]

First fuel gauge bar lasted 175 km. Not a record, but still good. The important thing is that the oil change in June appears to have helped a bit. I would be very tempted to try synthetic oil the next time. It costs about Cdn $30 more.

[60 Somethings]

Mileage report on new hatchback with 3,000 miles on it and initial oil change at 2,500 miles.

On last tank we drove 343 miles before refueling.

1/3 consisted of city driving and other 2/3 was a trip yesterday up to Timberline Lodge at Mt Hood. Pretty much all of it was with A/C on. The city driving was mostly with two adults in the car, and yesterday's trip was with three adults.

Vancouver, WA is approx 280' elevation. Went across to Portland and took Hwy 26 to Timberline Lodge turnoff at Gov't Camp (3,995'). The last 6 miles is a curvey road up to the Lodge at 6,000' (turned off the A/C for that part). Came down through Hood River Valley to city of Hood River, then back along Hwy 14 on the WA side of the gorge.

Stayed up with traffic all the way - just kept the revs up and it ran like a champ. Very smooth and A/C was great - it was a hot day.

Mileage came out at 34.7 MPG for the tank. Given the conditions we were very pleased.

Expect to get 38 MPG on drives to Seattle with the A/C on. We need to do that soon, and I will report the results.

[Tankota]

I'm getting about 34 average right now, at 1500 miles. 40% City, 40% highway, 20% L.A. Traffic. :rolleyes: And it's been so hot out where I am the AC has never been off since I got the car..

[johnson306]

My first tank came in at 503 kilometres. I have no idea how many mpg that is? anyone want to convert? that was using 37 L.

[asa805]

seriously i dont get this stupid crap. I got 27 my frist fill up and just got 24 my second! What the F&*( is going on!!!

I had low tire pressure.... could that be the culprit. I do mainly city driving, probably 85/15 with most of my driving trips between 5-15 minutes long. I dont rev the engine while its cold, am careful over bumps, dont go over 70 (usually hover around 60 like an old fart (im 27!)), and really trying not to stop short if i can help it.

So seriously... how come i am getting 10mpg difference between other drivers doing similiar driving? Ok maybe im doing too many short trips but i figure i shoudl be getting at least 30!!!

sorry but im starting to think this car is just a peice of shit in a cute cars clothing :(

The mileage is going to suck during the break in period. Some people didn't start seeing great numbers until their first oil change. Those numbers do seem low tho'.

[fnkngrv]

Maybe you just happened to get a dud. The lowest I have had so far was 37 or 38 and that was with 60/40 split I would think....60 being HWY. I now have 3015 miles and I am going to be taking it in for the first change this weekend.

5 Speed Liftback, 35/65 cty/hwy

Didn't use AC at high speeds on the last tank, it made a considerable difference.

In the case of the Yaris, the difference in fuel economy between the stick and auto versions is not big. If interested in verifying this, please check it out on www.toyota.ca. Just go to the specificatons page for the Yaris.
Moreover, IMHO, because the auto version has a degree of autonomy, it tends to give out fuel economy numbers closer (than the stick version) to the average, whilst a stick shift will produce numbers that vary greatly, depending on the user's driving style.
At the risk of over simplifying, I would say that one can use the stick shift to ,deliberately or inadvertently, produce low mileage by always using low gears, laboring/lugging engine etc. On the other hand, an auto transmission will normally select the best gear for the situation, at least most of the time and hence produce results that are closer to the norm/average.
Having said that, I would still say that the stick version, if driven by a proficient driver driving with a thrifty style, should produce slightly better numbers than a similar car with an automatic transmission driven similarly.
Also, I do not imply in anyway that poor mileage must be a result of bad driving style. There are too many reasons which can lead to poor fuel economy.

WOw! that is a WELL thought out statement(S). I wish i could articulate to this degree.
I agree completely. heavier engines/chassis will make automatic trannies less productive, but on a yaris it should be negligible..especially for crappy drivers :P
but, too bad we didn't get a 5th gear on the automatic tranny like the hondas :( it's like being in 5th instead of 6th nowadays.

4 more sets of numbers to report, as a followup to my prior post on this thread.

Per my regular 70/30 hwy/city mix -

5.93 L/100 km (zero A/C)
6.30 L/100 km (some A/C)

On a 1136.7 km total road trip (85 hwy/15 city, A/C running ~75% of the time) -

5.56 (!) L/100 km
In Monopoly money - 42.30 US mpg
In poker chips - 50.81 Imperial mpg

Back to the regular 70/30 hwy/city mix, and w/lots of A/C -

6.33 L/100km
...and back up to the low 6s I've been typically experiencing this summer.

It would appear that hwy running, for hours at a time, reduces the rate of fuel consumption.

Overall, these are substantial reductions from 7.1-7.2 L/100 km, when the car was still brand new thru the dead of winter. On the assumption that my driving style has been more or less the same, wear-in, usage mix, and environmental conditions seem to account for the rest of the difference.

I think my experience has been typical (no need to panic for the new Yaris owners).

Well, not much more I can add at this point. My Yaris has met all my expectations :smile:

A very relevant point for discussion here, TRD_Yaris:thumbup:. Thanks for showing interest in this subject. The common belief is that warm weather tends to produce better results. It should be right. Still, it would be satisfying to prove it with our own efforts here.
I hope all of us will keep on reporting fuel economy numbers year round. With a big data base, our intelligent members will be able to use their analytical minds to draw some useful conclusions.

[Pompeii66]

My first two tanks so far have yielded 32MPG.
I'm not going to get mad about it yet.
Only have about 600 miles on it so far, it's not even broke-in, plus it's been hot as hell here since I got it and the A/C is always on.

[asa805]

So since filling up the tires that were low i think my MPG is improving. Havent yet used up enough gas to tell but in the first bar on the meter i did 60 miles. At my last fillup i went 250 miles (24 mpg). Im thinking i have improved quite a bit considering there are 8 bars and i already did more than 1/5th of the miles on my last fillup and i only am up to my second bar. Im not going to get my hopes up yet until i get lower on the meter. Anyone know how many miles they are doing approx per bar on the meter?

[swng]

Re: asa805's question above.
I can only speak for myself. With a few exceptions, I have been getting 40 to 50+ miles per bar. The first bar usually lasts as long as two other bars, sometimes longer.

Tire pressure IS one of the MOST important factors in gas mileage. Though, inflating a bit too much may cause too much "floating" or bounciness in the tire sidewalls (depending on how stiff the sidewalls are to begin with).

Also, highway fuel economy is going to differ GREATLY between 50 mph and faster...how much of a difference i have not figured out yet.

The first few thousand miles tend to be pretty bad on gas, and the gas tank being kinda small makes it tougher to get a good average. My best method is resetting the trip odometer and keeping track of EVERY gallon of gas that goes in it (gas receipts help, especially writing the before/after odometer reading on each receipt). After about 500-1000 miles, you should have a MUCH better average than with 10 gallon. on a 10 gallon fillup, you might be off as much as 1 gallon since you can't EXACTly tell if you refill to the EXACT same spot as before...

As far as hotter temperatures giving you better gas mileage: i agree (from everything i've researched). Colder temperatures will give you better horsepower from the air being a bit denser, but this denser air entering the engine will require additional fuel to burn : therefore you end up using more gas. Though, a bit quicker acceleration should mean that you have to accelerate for a BIT less time..but this doesn't seem to be as big of a factor.

This thread has gone from good to EXTREMELy informative.

my car just hit the 10,000 km mark and i just filled up,
my average over the last 4 tanks is 6.1L p/100km or 38.5 mpg (u.s.),
i would estimate 60/40 hwy/city, driving most of the time like youthfully-minded senior citizen who on rare occasion likes to pretend he/she is a responsible yet thrill seeking teenager.

Just filled up with 44.027 liters (please believe it, its on the bill). Traveled 648.7 km.

Got 5500 miles on my auto sedan, with 50% hwy driving the average over the life of the car is 38 mpg, on a trip this past week on the highway with the AC running I averaged 42 mpg, can't beat that with a stick. With gas at $3 it seems that I should've spent just $435 to drive those 5500 miles

VERY NICE INFORMATION!! this IS EXACTLY WHAT I WANTED TO SEE, someone who has used gas receipts to verify EVERY SINGLE gallon of fuel they've put in the car down to the .01 gallon.
See, the inherent problem(s) with "calculating" your gas mileage based off one tank of fuel are:
1. Precisely refilling the fuel tank to the exact level it was when you refilled last is though, usually you're going to be anywhere up to 1/2 a gallon off (unless you REALLY know you're vehicle.. ). Therefore, if you figure your gas mileage, and you happen to be a half gallon off, this will greatly affect your math. on the other hand, if you use the fuel numbers off your gas receipts, you know EXACTLY how much fuel you used over MANY tanks, and you will still only be 1/2 gallon or so off since you only run into the problem of refilling to the same level as beginning level once. (brain fart..does everyone know where i'm going with this..i lost myself..hah haha hah i'm a little loopy right now....)
a 1/2 gallon off over 50+ gallons (about 5+ fillups) does not affect the MPG math as much..therefore leaving less room for error and more room fr adjusting to the good data you've received :thumbup:

2. driving for more miles will give you a much better "average" of your normal driving, giving you much more realistic numbers (realistic being what YOU will see). Just knowing a yaris will get 40+++ mpg on the highway in California in 80 degree weather with 60 percent humidity, no A/C, driving a steady 62.1 mph down a 5 grade mount in the direction with the wind isn't going to help you if all you do is commute around the corner, where you will be idling in traffic or warming the car up MORE than you will driving... personally, i drive my yaris a little faster than I know is gas efficient. Mostly because I'm driving delivery and i'm usually in a bit of a rush to make $ . Also, i tend to either skip 3rd gear (if i'm not gonna go over 40 mph for awhile) or I skip 4th (if I'm gonna be going above 40 mph like highway driving)..I don't know if this helps or hurts my gas mileage but old habits die young. I've been doing it ever since I drove my civic hatchback. it had enough power that i could actually take off in 2nd gear very comfortably..and going through gear on extremely short gears is a pain in the as$ for delivery driving 5+ hours straight...

[swng]

Many thanks for posting your useful thoughts.
I will be keeping an eye on my car's fuel efficiency on a long term basis, tank after tank, with a view to minimizing the effects of one or two times of especially good or bad results because of one reason or another, e.g. exceptional driving conditions (favorable or otherwise), or not being able to fill up to exactly the same level of the tank as the previous filling etc.
Also, I believe that starting with 2nd gear, if the car's design so permits, can help save some fuel. Too bad I drive an auto currently and therefore have limited ability to comment on aspects concerning stick shifting.
Please keep on sharing your insight!
