Default Just got an STi, bad mpg!!

Coming from a celica, this thing wastes gas like nothing!! I used to be able to travel about 20 miles not even using 1/16 a tank. The STi seems to use twice as much!! Dont get me wrong, I absolutely love the car, but the gas mileage could use some help. Does anyone know if the Cobb Accessport Economical map should help any? At least noticeable? Ive heard rumers saying the economical mode using accessport could give me up to 30mpg. Please clarify that for me.

The best solution is to just give me your car. Your driving style and conditions will have a greater impact than a chip.

Come on man, you looked at the sticker when you bought the car, right? Please tell me you did.

As far as your question about the Cobb AccessPort map, yes it will give you better gas mileage. Just remember that:

Gas + Boost = $$$

But it is worth every second of it.

if you want good mileage, stay off the boost, easy on the gas, lose some weight, don't use the a/c or any other electronics for that matter and stop revving at stop lights trying to impress ladies.

kthxbye

You can save a lot of gas by being gentle on the go pedal...try to keep it out of boost. But really, one should not buy an STi if gas is an issue...you are even supposed to be keeping it at 94 octane.

Every STI owner here will probably agree with you...it's just that we kinda' expected it to be bad gas mileage

yeah i never looked at the mpg when i bought the car, i came from a rsx and the sti eats gas like nothing.... i was shocked. at that point i was getting 200 miles per tank, which is horrible. These were my frist few months and i couldnt stay out of boost, and the pedal was always at WOT lol. Now I chilled out, especially with the prices to fill the tank, i squeeze out about 280 per tank, very noticiebale difference...

The gas pedal is what it is, if you dont press it as much or as far down, youll use less gas, its simple, just so tempting to always be on it!

LIES!!!

Mine says 93, 91 if necessary, for the WRX it says at least 91 or 89 in a pinch.

I get good gas mileage when I drive nice.

When I drive hard, that's when your money just burns up.

i dont agree...respectfully. Do you know what the tolerances in new engines are? its not an old small block chevy! engine advances have come so far that piston rings seat in extremely quickly in modern times. the hones on cylinder walls are extremely precise and machine finished.

now to the floor it and accelerate hard...you bought a sti, beat the crap out of it...drive it like to stole it...and dont drive 20 miles to save .03 on gas per gallon!

Who buys an STi cause they want it to get good gas mileage???

I thought it was expected with those cars that they would eat gas.

interesting.
the mpg in my 04 STi is not really worse than it was in my 97 Sebring Coupe.
of course, i bought it used, so it had no sticker to read.
i was not getting it in hopes of saving $ on petrol, so i will not complain.

my gf was shocked when she got rid of her 46+mpg 91 CRX (HF) and bought an 04 RSX S type last year. i told her she had gone from 60 HP to 210 HP (or 240, or whatever it is). and you know what they make HP out of . . .
gasoline.
