- Mon Dec 05, 2011 2:13 am #284146 My stock crx got about 400-440 per tank 10.3gal iirc your numbers are an exaggeration also cold air intake or "warm air" in 95% of the cars I've seen. Actually cuts your mpg not increasing it. Same goes for to large a diameter exhaust. No back pressure and you'll get passed by a smart car.


My .02¢

Change fuel filter $10-15
Change plugs and wires If they are old about $35-50 for some ngk's
check your oil level as well as coolant (obvious) but most missed
Ebay intake back to stock airbox (sorry you'll lose your swoosh sound during shifts)
Check your timing you didn't post your trim or motor but expect about 320-380 in a 92-95 hatch with a d15

- Wed Dec 14, 2011 2:29 pm #285401 Its possible to 500 from a tank.. you'll be around 42ish MPG.. take a gas can and fill it up then fill ur car up, reset your trip odometer and drive till I run outta gas.. then divided ur miles driven by the size of ur tank.. I got around 490-500 in old Ek(d16y8).. but this was in Florida gas has different octane in different states.. and elevation play a roll.. there's a lot more then just ur motor

Poor alignment, worn wheel bearings, even low tire pressure can all hurt fuel economy.
