The faster you drive, the more fuel you use. Contrary to popular belief, restarting the car uses less fuel than letting it idle. If you anticipate being stopped for more than one minute, shut off the car. Wide-open windows, especially at highway speeds, increase aerodynamic drag and the result is up to a 10% decrease in fuel economy. The air conditioner puts extra load on the engine forcing more fuel to be used. Heavier vehicles use more fuel, so clean out unnecessary weight in the passenger compartment or trunk before you hit the road. Under-inflated tires make it harder for your car to move down the road, which means your engine uses more fuel to maintain speed. Keep your tires inflated to the proper levels.
