Maxing out your gas mileage requires a few compromises. Inflate your tires to the maximum allowable pressure as stated on the sidewall, usually around 44 psi. This will give you a rock-hard ride, but it's the way to the least amount of rolling resistance. Reduce any unnecessary weight in the car. When accelerating, don't let the engine go over 2500 rpm before it shifts. This basically means to act as if there were an egg underneath the gas pedal. Time traffic lights so you don't have to stop. Drive at the speed limit or 5 under on freeways. Drive with the windows closed, and if you must use the A/C, keep it about halfway up the temperature dial, not at full cold, and the blower at low speed. This will reduce the amount of time the compressor is on. Any extra electrical loads put extra stress on the alternator, so keep those to a minimum. Of course, doing all of these things isn't practical in the real world, but I did all of these things for one tank of gas, just to see what kind of mileage I'd get. I got about 35 mpg, and that's with a 3.5L H.O.
