On the highway I get 26 mpg going 65mph. I am quite happy with that.
City driving on the other hand really sucks.
I've never checked but it is horrible but typical when compared to the other guys I know complaning about there millage with V-8s in the city.

It really depends more on driving habits than engine size sometimes. I know a guy who has a 2000 Prelude with the V-TEC 4-cylinder *laugh* who gets worse mileage than I do with an engine twice his size. Might also have something to do with the fact that V-8s tend to make power down low, whereas a 4-cylinder that makes lots of power has to rev to 7500 rpm to do it.
