I own a 1998 Prelude which has an automatic transmission, I purchased
this car about 7 months ago. What kind of mileage do you Prelude
owners get?

I seem to average around 20 mpg which only gets worse in cold weather
driving. On a full tank I might get 280 miles, some times 270 if I'm
lucky once in a while I get about 290 to a tank. This seems to be
about 40/60 city & highway.

I like this car but would like better MPG. I recently changed the
plugs & air filter but that's it.

Should I be getting better than this?
