Brand new Yaris, very poor gas mileage

[minicorolla]

I shouldn't post this. I'm down to 36.7 mpg with winter gas and studded tires. I think it sucks. Mosty highway with warm ups cuz it's been so cold.

[AppleJacks716]

When I bought my '10 I couldn't break 30 mpg driving highways. Now after the first oil change I'm up around 36 mpg. Nothing in my driving has changed.

My Yaris definitely dislikes cold weather! Check my fuel economy by date. It is lowest inthe coldest months!

That's strange.
Do you drive a lot of hills? Have lots of passengers a lot of the time?

We also have a newish 2010 (<600 miles on odometer). It's an AT sedan and we've certainly not gotten any less than 35mpg so far. And it's probably closer to 37mpg.

Doyou warm up the car in the morning?
I never warm it up; I just turn it on and go. I don't much like doing 0 mpg for any length of time.

I didn't expect my Yaris to get 35mpg right out of the box.
Can't wait to see what it'll do once it's fully broken-in.

Go Yaris!

Do have the car in 3rd instead of overdrive ? That'll do it . You should be getting at least 32 m.p.g..

We bought our 08 new and have been getting 35mpg day in day out since day one.

I've got a 2010 sedan with an automatic and my mileage is strictly limited by my driving style. I'm very happy with my mileage.....even more so since I consistently beat my wife's mileage with he Duma** Kia Rio,lol

And my mileage average as posted by GasSavers was 39.2 till winter gas got here :(

I have found during the Fall to Spring when I am running my defroster,which in turn uses the AC pump to dry the air I lose a few miles per gallon.....but I am still getting average of 30mpg a tank,with heavy 17" wheels,intake and exhaust are not helping either....

Summer I get average of 35mpg a tank,same wheels,tires,intake and exhaust.....U rarely use AC during the summer,I like the window down and warm weather....

give the car a few miles....think mine finally seemed broke in and giving me the right milage per gallon around 8000 miles on the thing....

I drive a split of highway 65mph and intown 35 mph per tank.....never baby the throttle....I am used to driving a big V8....so anything in the 30+ mpg range and I am super happy...

Plus since car is my DD and work car,which they pay me milage....I average $300 a month in milage money....which pays my payment and gas....and some months an oil change....

also once car is broke in.....swap up to synthetic oil....my mpg went up 2 mpg just by doing that along.....and car runs smoother.

Mine also jumped after the first oil change.

I think Toyota must have a "safe tune" for break-in. After the mile counter is re-set the first time it goes to "normal" mode.

So what's the deal with the US Yaris? My 2000 Toyota Echo (US) two-door sedan got 48mpg highway, excellent fuel economy. I see the 2011 Yaris stats are 29mpg city / 36mpg highway. Why has it dropped? I am now in Ireland and have a 2008 Yaris TR D-4D diesel, get around 70mpg highway and nearly 60mpg city. Why don't they market cars with good fuel economy in the US? I've never understood it.

[rningonfumes]

"WE" the U.S. don't really think of fuel economy much until it hits us square in the face. People honestly don't notice their fuel until gas prices climb and then we start hearing complaints about fuel prices as if they didn't notice that the prices jumped steadily for the last year (any year).

Thus... cars which have high fuel economy don't get much interest unless it's the hip electric hybrids. It's a stigma to drive a small car, so people like their larger cars, in the US at least. Small inexpensive cars (which happen to have high fuel efficiency) here in the US represent financial status. Basically if you have a small car, you are either poor, young, or are in school.

That said, our federal ratings did not drop, new standards of measurements were put in place and according to those new standards is why we have the new- lower figures. The new standards affected all new vehicles in the US. We don't get the diesel version here.

And lastly, every country uses a slightly different unit of measure so MPG numbers will vary and will need some conversion.

what gas brand u guys use ? 87 or 89 octane ? why I only got 30 mpg no matter what season is

[Hershey]

87 w/ 10% ethanol .

[Imagine]

Be Patient! Give it till about 100K miles, by then it will almost be broken in.

Fuel mileage is dependent on a ton of factors from tire pressure, driving conditions, fuel quality, car config, etc.

I took a trip to New Jersey from Ohio. On one stretch, I averaged 48 mpg on a fill up. I drifted a Semi for almost 300 miles at 65 mph on 87 octane.

[STC]

Winter bad, summer good!

Ethanol bad, non-ethanol good!

Driving style, weather conditions, driving environment, and gas type all play a role in your MPG.

I'm taking a dive using ethanol gas now... I wish non-ethanol was available.

Cheers!

I think a lot of "average" drivers will never be able to reach epa highway mileage. Maybe get a scangauge to keep an eye on your driving and research hypermiling.

[birdman]

That's odd. I live at 3500 feet in the mountains with lots of snow, ice and slush and I am getting 32.8 miles per gallon with most of my driving in town. I get this even with a lead foot. I can get high 40's when on flat highway with the aide of the Ecometer. Maybe you should have an exhaust analysis performed to see if there is an indication of something out of spec.

[bentjazz]

Birdman, how does an Ecometer help you increase your fuel efficiency? I've heard people talk about these devices, but I personally don't know much about them.
