Fuel Saving Tips
Cars typically are more fuel efficient when the air conditioner is set to re-circulate interior air. This is because keeping the same air cool takes less energy than continuously cooling hot air from outside. Of course, turning off the air conditioner saves even more fuel. For driving around town and not at highway speed, keeping the windows open and the air conditioning off is the more fuel-efficient way to go, if you can stand it.
