I drive my 95 coupe 4 miles each way, to work and back with an occaisional (once a week or so),trip of 15 miles or so each way. Right now the average is reading 22.6, and that computes when the math is done. When I take it on the road, I get 29MPG on routes that are pretty flat. In Western PA this summer it got 26 with about 70% turnpike, and 30% state routes. I always figured my car did better than the EPA estimates because the EPA figures this statistically, and not with actual driving. The Corvette has way better aerodynamics then the EPA's stats account for. If my car were to give me less than I am used to, I would start looking at cooling temp sensors, and O2 sensors. Either it is running in warmup enrichment, or O2 is sending low voltage.
