Fuel Saving Tips
Most cars' AC uses as much power when it's on low as when it's on full. The compressor is still running all the time, it's just being mixed with uncooled air from outside. Instead, if you need AC, crank it as cold as it goes and cycle it on and off by hand to moderate the temperature.
