I've got a 1993 Chevy Lumina with 3.1 liter V6 and automatic transmission. I've tried my best to drive conservatively but the best I've managed with the thing is 24 mpg with mixed city and highway driving.

One thing that's weird about this car is it seems to coast better in drive than in neutral. When I put it in neutral it slows down very quickly. I've never had a car that does this. As soon as you put it in neutral it feels like when you let off the gas in a high compression car; instant deceleration. Any ideas why it does this? The brakes are all fine, no dragging brakes, the wheel bearings are fine, too. And I can't understand why it coasts just fine in gear.

Any ideas on what I can do to increase my fuel mileage? I already shut it off at stop lights, keep my tires at max sidewall pressure (40 psi) and drive as conservatively as possible.
