60K maintanance/ mpg issue
I just changed my oil about 300 miles ago, im currently at 58.700 miles. so i see according to the manual i should do a spark plug change and a trans flush in addition. can either of those two things affect my gas milage??? Driving like an a$$ is behind me, im really trying to be conservative but somehow im just barely gettin 25 ave. mpg (mainly city) I would think with my intake/exhaust combo my gas milage would be somewhat decent but, its not. Anybody have any thoughts on what could be affecting my gas milage that bad (im not even meeting the city average according to the company of 28 mpgs)
