does your car feel any quicker.
gas mileage will decrease in the winter due to the temp change,winter tyres are heavy.try them in the warmer months.

Keep in mind folks, that 1.8TS was NOT designed for fuel economy. It was designed for zippy fun. Add in some very cold city driving, with plenty of stops and starting of the engine, and it becomes exactly like my case.

Kou, privat netz 17 inch wheel weight is 17 lbs and the tires are 19.............17+19= 36

(stock wheels are 15, and eagle LS are 17) that indeed equals 32.

Im not sure why some folks hate on larger wheels. Investing in light and/or larger wheels and nice tires has handling benefits especially over the awful stock tires. Its not like im running dubs on the thing.

The temp, and conditions were taken into account already in the analysis. something is up other than my wheels and tires

ps, thanks for answering my PM's

20MPG, woah. That sir is not normal. Going to uni everyday, getting stuck in the wort traffic imaginable every day as well, I still get 40+MPG, my best so far was around 52MPG.

Should definitely check with dealer.

And I'm guessing you don't see a day below 80F in sunlight, correct?

The Netherlands is a cold, cold place... And it would seem the Yaris is extremely sensitive to temperature. The hotter, the better!

kou · 01-19-2009, 11:34 PM

the summer i average 40ish now in the winter its 32-35ish,but there is some extra get up and go in the cold.

Ryu · 01-20-2009, 01:07 AM

Are you sure that you do the right calculation to get that 20 MPG?
I am guessing that probably the way you calculate might not be accurate.

XYaris · 01-20-2009, 07:47 AM

miles travelled divided by gallons it took to fill up...off to school, ill do a mini test for this trip.

Was your gas mileage better on stock 15"s?

thebarber · 01-20-2009, 11:29 AM

well, w/ 17's youre pushing all the weight to the outside of the wheel and tire....which increases the rotational mass....3lbs per corner is equaly to like 30lbs when you try to get it rolling....

i know crandall has 18lb 17's w/ 215-40-17's and he gets about 30miles less per tank than i do w/ 14's

also consider the cold weather....cold, thick oil is harder to get moving when you first start the car

and the idling....just burning gas sitting still

what also MAY be a case is if youre still trying to take off fast AND granny shifting at 2000 or 3000rpm.....wide open throttle is wide open throttle no matter what gear youre in

and what gear do you cruise at in the city....say at 30mph.....3rd? try 4th

XYaris · 01-20-2009, 10:10 PM

39.8 miles, 1.6 gallons of fuel.

yeah, thats 24.8 mpg

spare me the wheel hating, thats just plain messed up. I keep reading folks comments that they drive hard and cant get below 30 mpg. I drove my impreza like i stole it (especially in the winter ) and got 25 mpg consistently.

I hear what yall are saying about WOT even if its only til 3000rpm. Im not gonna lie, I like to scoot around but i have been curbing my desires in the interest of not killing my car and seeing if the mileage improves. its strange that its running perfectly otherwise.

I can make it to a dealer until friday. hope the car lasts that long

gid · 01-20-2009, 11:47 PM

XYARIS , I take it that it's an automatic ? Do you possibly have it in 3rd GEAR instead of OVERDRIVE ? How's your tire pressure ?

kou · 01-21-2009, 12:32 AM

noones hating on the wheels just put your stock ones on and see if you have a change in power and FE.

Ya - bet this is it. I remember another poster drove the auto for months complaining about low mileage and it turned out to be the same issue - driving in 3 instead of D.

or how about leaving the A.C. button on . Noticed I had somehow hit the A.C. button to the ON position ( GREEN lit up ) , is easy to miss , not very bright or large . Seldom use it for warm weather or the defrost mode for windshield , if windows fog up roll down window a bit , fresh air helps that . How long it was on I don't know

. Sign of progressive aging

gid · 01-22-2009, 12:27 PM

or both A.C. on and O.D. off .
