gas mileage

You can get great gas mileage without trading cars. Here is all you have to do.
Drive no faster than the speed limit.
Keep your tires properly inflated.
Change your air filter every 25,000 miles.
Gain speed slowly, and start slowing down way back from where you plan to stop.
Avoid downshifts.
Gain a little speed going down hill and lose a little going up. Cruise control can work against you in hilly country, but in flat country it will save gas.

I didn't say it would be easy, but if you do those things, you can increase mileage by as much as 10%, and maybe more if you have a gas hog. If you save only three gallons a week, that's six bucks.
