like mr. northey has asked for nothing but city driving lots of stop and go. that would probably be about right. but if thats with nothing but highway driving i would start thinking that the tires need to be downsized. is it an auto trans or stick. one thing you could do is go through and change all oils, to synthetic, something like mobil or royal purple.
