Brand new Yaris, very poor gas mileage

[hatchy]

Hello everyone, I just bought a new 2010 Yaris hatchback (40 miles on it) a few weeks ago and am a little dismayed about the gas mileage. I've filled up twice since I bought and have only averaged 27 mpg both times. I drive normally, with a mix of city/highway. I also know it is the middle of winter and sometimes "engine break in" can affect fuel economy. However, in everything I read it seems people are at least getting 30 mpg (regardless of the season or newness of the car).

Should I be concerned enough to take it back to the dealer and possibly get a different one?

[Altitude]

I wouldn't be concerned. My winter mileage is in the high 20's/low 30's. Summer mileage between 35 and 40.

Do you warm your car up before hitting the road in the morning? That'll eat into your mileage. It has been widely reported that mileage gets better as the engine breaks in and while I can't claim to have seen much difference myself, I chalk that up to driving in less than favorable high MPG conditions (year round ethanol, high altitude and lots and lots of hills.)

[hatchy]

I just filled up to test my third tank of gas. On the last tank I let the car warm up a few mornings before work. This time I'll make sure to not warm it up at all to see if I can get closer to 30 mpg.

Ive owned 7 Toyota's and everyone usually takes about 6-8k miles to balance out on fuel mileage..Also my Yaris HATES winter gas I loose about 3 mpg my wifes corolla very small change and my tacoma looses about 1.5 mpg.You will have very inconsistent fuel mileage for a while.

[severous01]

it's called a break-in period. that's why you shouldnt add any additives or change the oil before the first oil change is required. the only engines that i know of that are broken in at the factory are the ls7 and ls9, the viper rt-10 and srt-10 trucks. BMW m-engines are filled with a break-in oil and must be changed within 1500 miles and cannot be run over 4500 rpm.

once you bust the break-in period you'll notice significant power and mileage gains. and it's relatively quick....within about a 100mile period. it's like the car is a terd and then it's all of a sudden good car.

my car had 475mi on it when i bought it...i drove it for 6-8 tanks and averaged abotu 28mpg. now i'm hitting high 30's all the time with the ac on and doin bout 80 on the freeway. i was rough on it to begin with....breakin it in. hitting decen rpm, high demands, stop n go traffic. and once it broke i toned it down and looked for mileage.

[TLyttle]

I just did some checks on my 07 sedan, and found a 10-15% drop in the C/D; culprit is the snow tires, nothing else changed. This directly correlated to my drop in mileage, something to consider...

[thebarber]

4 banger winter mileage sucks (relatively, of course)

[attickt]

I bought my car in september with 25,400 miles on it and iv'e been getting 30-32 mpg even now in winter I don't notice a difference, but I do run sta-bil in my fuel to control the ethanol wear and tear, as well as to clean the fuel system and keep the fuel fresh.

[SpaceShot]

You might check your tire pressure. I found mine quite low after dealer delivery. Perhaps to make for a smoother ride for test drives.

I certainly noticed a bump up after 5k break-in and again around 50K.

[MadMax]

I gotta ask, it is a manual or automatic transmission?

There have been several new Yaris owners who have accidentally bumped their shift lever into '3' with the automatic; and since there is no tachometer it's not always noticeable. The only way to tell is by the gear indicator on the dash, or to do what I do which is make sure the shift lever is in the far right position.

Otherwise, my Yaris also suffers from winter gas. I normally get ~35MPG, but lately it’s been down to ~32MPG. Now I see where they want to bump the ethanol content from 10% to 15%, which will only make things worse.

But give it time, most folks report an increase after the first oil change which is at about 5000 miles.

And congrats on the new Yaris!

Cheers! M2

I average about 28-31 mpg city and highways, but out here I am stuck in traffic, lights waiting on people and I also warm the car up for about a minute or so. I got a 3door automatic.

Thats true many ppl on automatic yaris on the highway are using 3, and that forces the engine, so u will expend more gas, if u do this on 80km/hour shift to D and u will notice the difference

P.D. sry for my bad english :P

when i test drove my yaris i drove it around in 3rd gear XD i didnt notice until i took it home that night that.

I agree, check the tire pressure. I am certain the dealer has them as low as they can get by to keep the TPMS from going on, so they will have a softer ride.

Also, with all the snow we've had here in Indy since you got your car, I'm sure that could affect mileage also.

[Hershey]

Low 30s are the norm for our 3 door w/ auto during the lousy days of winter . So many negative impacts .:frown:

yeah, I got average 30 mpg too, mine is a 07 sedan

[jambo101]

Gas mileage sucks in the winter, if you can get 30mpg you are doing good, Long highway drives in the summer will have those mpg figures up in the mid 40's.

[cougar65]

I'm at 6000 miles in my yaris, and I am averaging 31.2 mpgs mixed city and highway but on my 400 mile trip i got 36.4 and on my other trip trying to be eco and going 55 mph i got 40ish.

[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.

[CKaelin]

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

[HYang]

I've filled up twice since I bought and have only averaged 27 mpg both times.

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!

[Hershey]

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

[Tom48]

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

[sickpuppy1]

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 :(

[bzinn 1]

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.

[Flipper_1938]

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.

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.

[nachtjenevel]

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.

[mupy]

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. :thumbup:

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! :smile:

[xaero_81]

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.

[Imagine]

An ecometer shows you what your mpg. The harder you are on the gas the more you consume. This allows you see the effects your having on your mileage based on how you change your driving style. It does make a difference! You can make a game out of it and see what nets you the most mpg. Hard trottle your mpg drops.. Coasting it goes way up. You'll start to let off the throttle more when possible to net those gains.

Great way to increase those mpg numbers.. also a great way to see how fun (spirited) driver hurts it. lmao.

[bentjazz]

Imagine,
What kind of gas mileage do you get from your 3 door?

[Imagine]

I was routinely getting about 30-35 out of my '07 auto liftback. I haven't run a full tank through my '09 yet to see how it's doing. I expect this tank to be less than I would get normally since my fiancee drove it to downtown Cincinnati yesterday and put about 150 miles on it.

I have 220 miles on this tank and it just dropped to 3 bars. I'm going to say it will be close to mid 30s by the time I have to fill up.

That's with 17 inch wheels and 27K miles.

[Imagine]

Filled up today. Got 33 mpg out of mixed city and highway driving and 17 inch wheels, curious to see what the next tank is with less city.

[marcus]

yaris hatchback manual 4 years old using regular and about 50lbs of shit on the back and aftermarket rims and tires about 3lbs heavier on each corner. winter 32-33mpg, summer 36-37mpg and record 45.2mpg

[MadMax]

Filled up today. Got 33 mpg out of mixed city and highway driving and 17 inch wheels, curious to see what the next tank is with less city.

That's about what I am getting in my 08 auto LB with 17" wheels (which is also BSP, by the way! :thumbsup:)...

Cheers! M2

[malibuguy]

my first tank of gas i got 37.7mpg...& i wasn't exactly trying to save gas....2nd tank of gas was 42.2...still not really trying....3rd tank...i dunno yet...i'll find out tomorrow...probably upper 30s cuz of the rain & i had to keep using the defroster

[hyprmiler]

As others have stated, change your oil after 3K and move to synthetic and you might see a slight improvement due to the lower viscosity.

Personally on my 08 Yaris I run 40psi in all 4 tires / have a scangauge / drive no faster than 60mph on the freeway and in the summer I'm hitting mid 40's without trying.

to compare apples to apples

In the winter I'm getting 35mpg on average. Again YMMV, but 95% of my driving is freeway and only for commute to work.

[malibuguy]

BTW i got 40.7 on my last tank

i'm switching to mobil syn at 1,500 miles....then at 5K i'm doing another change plus switching the trans to mobil syn

i'll probably jack my tire pressures up soon...i'm just trying to enjoy the car completly factory spec for at least a month, L O L, its been so hard to resist putting an exhaust on it

[Slinger007]

My yards Sedan is an 09 so it was two years old when I got it, I have had it for a year (Got it in March 11), and until november (2011) ish, I was getting 700km(434 Miles) no problem to a tank of gas, and thats using A/C (I still had no problem getting 700km(434 Miles) even in summer with AC on)

I pushed it a few times to 740km(459 Miles) but made sure a gas station was near by. I drive 115km(71 Miles) one way to work every day, mostly highway, and I was getting 3 round trips with out having to fill up. For the last 4months, I have been lucky to get 640km(397 Miles) out of a tank, the only thing thats changed since november is the colder weather and yes I put on winter tires. Is it usual to lose between 70 and 100km(43-62 Miles) in gas due to cold weather and winter tires?

Oh the car had 34k when I got it and in a year its now at 81k...

[Spidermandud]

I've noticed with my hatch I'm getting a couple less mpg; I'm at around 88k miles myself. I'm puttin my money on the pressure and temperature changes having a hand in it; but don't really have any way to prove it.

[why?]

yes, winter, plus snow tires, plus winter gas will lose gas mileage. sometimes as much as 3 or 4 mpg or more.

[charles nelson]

I have been very happy with the mileage of my 2008 auto-trans Yaris. I averaged high-30's as soon as I drove it out of the lot. By 5000 miles, I was averaging low 40's. I made sure that the tire pressure was correct. Following guidance from Pop Mechanics mag., I accelerate fairly quickly to get to higher gears and try to time my passage through signal lites and slow down slowly if I can. Doing jack rabbit starts and stops...my Yaris drops into the high 20's-low 30's. Most disturbing is when fighting strong head winds on Freeways and mpg drops to mid-to-low 30's.

[dobbiedoo]

2009 yaris S 5dr auto I have gotten from 33 to 35 mpg in the winter, and 36 to 40 mpg in the summer. Tires are 38 psi.:smile:

Speaking of fuel efficiency, just watched a documentary called "Collapse" about, well, lots of things, but in particular concerning how future oil shortages will affect the world. Being Yaris owners, I think we are all doing the right thing by owning fuel efficient cars that ultimately decrease energy demand (thereby decreasing our dependence of foreign sources of energy), increase national security, and probably help to mitigate the impending future oil shortage.
Check it out. The documentary is pretty good. Michael Rappaport is interviewed....

^ I've seen this documentary. It is good...

With the present winter of 2012 gas prices have been the most ever for any winter season? Demand has been the lowest? Go figure? Wouldn't peak oil be bases on the law of Supply & Demand??? One has to look at short term and long term also. With what I'm seeing definately the market is being manipulated. Speculation must be the main culprit... mind you short term. Long term, there is manipulation occuring that probably far exceeds our understanding.

[Idahotom]

I realized something interesting today about having a ScanGauge:when someone else drives your car, you can access the wealth of information it retains, and see how your personal driving stacks up.

I had to have someone drive my HB 45 miles for me, they averaged 35 mpg, I get 41 on the same route. They hit a high of 78 mph, my max was 65, nuff said.

total and utter rubbish. Garbage like that is put out by people that have zero clue about real science, and just want to control people.

The most important part about so called fossil fuels? Even the russian scientist who came up with the theory changed his mind a decade later. Oil and the like are processes of our planet, and always have been. There is nothing to see here but people doing everything they can to turn others into sheep.

Supply and demand of oil is manipulated by many things. The most important thing is that not only does the US need to import oil, it also needs to import refined gas, because we don't have the refinery capacity that we need. The last oil refinery that was allowed to be built in the US was built in the '70's. Secondly, the USA has enough oil just in our own nation to supply ourselves for many many decades, yet eco freaks and eco terrorists would rather you and i suffer than actually go drill it. Thirdly, since the Keystone Pipeline was killed gas has skyrocketed because that was a gigantic supply of fuel that would have helped prices tremendously. Speculators are a source of gas price manipulation, but OPEC has recently decided to cut its oil supplies because demand is dropping significantly, and that also makes oil and gas prices rise.

To summarize, $1 a gallon gas or less could be easily had by drilling for oil in the US, forcing company's that drill oil in the US to sell it here, building more US refinery's, and basically telling eco freaks and eco terrorists to jump in the arctic ocean with their beloved polar bears.

[The Limo]

I hope all these eco freaks and terrorists only jump into the Arctic ocean off the coast of Alaska. None allowed in Canadian Arctic waters.

Canada, at the moment, has more oil than it knows what to do with, yet when I filled up my gas tank last night I paid $1.279 CAD per litre ( about $4.85 USD for an American gallon). So there is no guarantee even if you have all kinds of oil that you are going to pay a lower price.

unfortunately most of that is taxes, like most of the rest of the world. The US is one of the few areas outside the middle east that pays close to actual cost. Well maybe not close, taxes here even are 50¢ to $1. Completely insane. The government types need to be taught they can't steal from us.

The US and Canada have two different models when it comes to fuel tax. In the US, we pay two sales taxes, one state and the other federal. The federal tax goes directly into the highway trust fund and the government gives it back to the state by some complicated formulas that involve vehicle miles traveled, lane miles...and a bunch of other little factors. The state gets to do whatever it wants with their part. In Canada, the tax on gas goes to many different funds. Only a very small portion goes to fund highways. I always wonder why Canada has such a high gas tax when they are flush with gas.

Well my i see a tren of complaints but the bottom line is all in how you drive and remember the 5 speed will get on averege an extra 5 m/g

[MadMax]

...and remember the 5 speed will get on averege an extra 5 m/g

In what world is this? The MT is rated all of 1 MPG better than the AT and that only for highway driving, in the city the ratings are the same (Source for 2007-2010 Toyota Yaris mileage ratings (http://www.mpgomatic.com/2008/01/23/toyota-yaris-gas-mileage/)).

Practical experience by members of this forum has confirmed that.

Welcome to the forum, but while posting on here be sure to differentiate an opinion from fact! :thumbsup:

Cheers! M2

[charles nelson]

When I bought my '08 Yaris with AT, I asked my salesperson what type of penalty in mpg I would get in buying it with AT. He said that both the 2007 and 2008 models were getting a slightly higher mpg with the AT than the MT. He thought it had to do with the engine computer being better at shift points than most drivers using the manual transmission. My mileage was 38-42 mpg right from the beginning (at about 55 mph). After break-in, I have averaged mid-40's. My dealer has said that the newer models were also giving better mileage with the AT than the MT. Of course, your mileage can vary by how you drive. Re: the woman who won the civil case against Honda because her hybrid didn't give her what the EPA sticker said! I bet I could get my Yaris down to 10-15 mpg if I had to...burning rubber, topping out at max speed on the Freeway, etc.

[why?]

yea some of the best mpg's come from members who happen to own auto's. The Yaris auto is a darn good one compared to others.

The reason that suit worked is because the Honda dealers were doing some really shady unethical things with the gas mileage numbers. Making all sorts of impossible guarantees.
