Been into cars for a while, and the whole eco modding is a bit new to me, but I hope to learn more.
So far I have a 1998 Honda Civic DX with a 5spd manual tranny. With mixed driving I have obtained 35mpg when I first got it. Now during the same trips I get around 40. I have light weight wheels, intake/exhuast, did a full tune up, and eased off the gas. With more highway I've reached as high as 45 mpg, and that was before I did quite a few things. In a few weeks I'll let you all know what it pegs at.
Hope to learn more this looks like a cool place to hang out.
