Tire pressure will make a huge difference in your economy. But, if it's that much of a concern, the S2000 isn't the most economical vehicle out there so it's something I've learned to live with. You can't have everything.

 

yeah my milage was the same when i bought it. Does my oil filter have anything to do with it? Because last time i got my oil change at Active Green & Ross, they gave me some cheap filter =\ but was for the s2000. So I guess once i change the air filter to the OEM one (which most of you guys vote for) i will see a slight change i guess (When i said black i meant my filter is black as in dirt as hell!!). When i Granny Shift the car with very little throttle, my milage only improves about 15miles/tank.... so i just decide to drive entheusiastically thanks for your replies, and im still listening for more input.

 

yah just get oem, its fairly inexpensive i think

 

what about aftermarket replica of the oem (cone shapes and same dimensions) because that only goes for 18 bucks canadian

 

mine is 250 to 300, 350? thats some bad ass, not BAD at all.

 

go with either k&n or oem quality is unquestionable (at least for the oem) some people say k&n filters dont filter as well as oem. i beg to differ.
