Not so good gas milage, what could cause this?
I have been getting some not so good gas milage on 91 octane too.
Rebuild B16A 16dgrees timing (stock as per manufacture) running off a stock p28 map (maybe this could be it)
Cometic head gasket 9.7:1 CR
Brand new spark plugs, and O2 sensor, plugs have a gray/brownish tinge, burn the fuel perfect, so why am I using up so much fuel in the city, I never got a chance to see how the car does on the highway yet, but ok from 3/4 of a tank I am almost near empty and did just 277 kilomiters, I say I can pull off about 320-340 before I hit empty.
What else could cause bad gas milage? I dont have an EGR system, I just unhooked my PCV system and vented it to the atmosphere, I'll see if that helps any.
I have not yet changed the fuel filter, could this cause bad gas milage?
What do you guys think, because I cant seem to think of anything else that could be causing this.

I haven't been getting good mileage on the stock dx lately (315 miles/tank), so today I decided to put more air in my tires. Going from 20psi to the max of 44psi should help.
Check for fuel leaks at the rail too.

and then only take 1 shower a week and share the same towel with your *** dirty girlfriend for 2 weeks at least, then steal a towel rack before you leave.
