New engine MPG

[Kitt]

Just to keep you guys posted - I was able to drive 275 km (171 mi) with a full tank. So it looks like it improved slightly, or I'll say it is still within the error margin.

That's ridiculous. Something is seriously wrong either with your car or your country's fuel supply.

A full tank of gas should give you at least 320 miles (512 km) before the gauge starts flashing.

Are you using cheap gas? Ethanol? Switch gas stations. Those discount gas stations really aren't a discount.

[Kitt]

we used to have ethanol here but later on the government decided to stop using it. We have 91 and 95 octanes here, toyota said I can use either, I am using 95, and it is not the same station. Now that I recall, I opened a thread regarding this a while ago, before I purchased the car. (http://yarisworld.com/forums/showthread.php?t=54822) In comparison, according to the specs, my first yaris weighs 2943 pounds and the new one, 3306 pounds, 363 pounds more than the old one. I was told then that it may impact slightly the fuel consumption but not this!!.

This just does not make sense. Do you still have your old car? If so zero out your odometer and then drive somewhere a good distance away. Get that number. Then take your new car, zero out that odometer and drive the EXACT same route. Get that number. Are they the same?

If you don't have the old car try a GPS unit. Zero out the GPS distance traveled and the odometer on the new car and drive. Are the numbers the same when you stop?

I'm willing to bet your odometer is actually showing miles.

[Kitt]

yes, I'm totally agree with you. It's as weird as it sounds but both cars are set for kilometers. In fact, I use waze very often and it shows the speed and it is pretty much the same as my odometer. I have a scangauge in the old one and the speed is acurate as well.

I just took these pictures of both odometers and they both say KM/H

That is the GVWR (Gross Vehicle Weight Rating) not the curb weight. They only weigh in at a bit over 2000 lbs. and the new one about 2300.

How many gallons did you use?

That's speed. We need to verify distance. Even though pic shows km it is possible that it is inaccurate.

Granted I'm grabbing at straws but something is wrong here.

What kind of rpms are you turning? Could transmission be stuck in a low gear?

again, there is definetly something wrong here and I was praying that it was the odometer showing miles instead of kms but.. no.

Did the test with my cellphone's gps but it is showing the same

I don't drive it at more than 2k, always try to maintain the eco indicator on.

I misplaced the paper where I wrote it down but it was about 10 gallons

which is not a great difference.

It finaly got 1000 km, so I am taking it on monday to the dealer.

[IllusionX]

20mins to do 4.8km? That's major traffic. I would say it is normal to do just under 300km with a full tank with AC on.

Yeah that does seem like heavy traffic. That might have something to do with it. If all your driving was in those conditions your MPGs would certainly be low. But I thought you said that normally you drive in moderate traffic.

Otherwise I'm at a loss. Like I said before any engine showing those numbers would almost certainly be showing other signs of trouble. With a new engine that seems unlikely.

Undetected fuel leak?

I don't know. Let Toyota figure it out but something is definitely wrong. I never saw less than 28.8 MPG and this was in heavy city traffic. Good luck.

Just a wild thought. Check your air filter for being restricted or wrong direction,
Maybe just wrong filter.

A blocked air filter will only restrict power output. It has little to no effect on mileage.

I did an experiment when I worked for Toyota to simulate a mouse nest in the airbox by putting duct tape over all but 1 square inch of the filter before there was a reduction in power from a V6 Highlander. Because the mass air flow meter only reads what's going into then engine.

Nah, that's not my usual traffic, I got a traffic jam on the way that kept me stoped for a while.

Yeah, i'm taking it to the dealer tomorow. I'll let you guys know how it went

[WeeYari]

Just a question;

In this vehicle's short life, has it ever been allowed out to really stretch its legs? I mean gone out and done a good long drive, getting up to decent uninterrupted cruising speeds. Or has it done nothing but short, slow trips?
