I dont get anywhere near the great mileage that every one else seems to be getting. I have a 94, 5-speed LS. The worst I've gotten is about 17, the best is about 24 all city driving. Straight highway I got about 32. And that was only a couple of times. I live 5 miles from where I work, so its all city driving for me. I have 218,600 miles on mine, and only use premium. Any know of any way I can increase my mileage? My teggy is all stock by the way. Even had the original clutch in it till about 2000 miles ago.
