did you know that Gtp recommends prenium or they will loose power? that might help with gas mileage too.

considering the EPA rates them as 16MPG in city, i'd say you're about right.

My 96' Intrepid was 12-14MPG in town. My Alero didn't do much better than 16-18MPG in town. My 95' Cutlass was around 16ish. I'd say 15 is pretty good.

15 sounds normal, i confirmed with a friend who has one as well.
