So Does Your Car Heater Waste Gas? Not necessarily. It uses gas in the sense that it turns on a fan to direct the warm air inside the cabin of your car but the consumption is negligible at most. The heat being used is there for free and it’s only a matter of taking it from the engine into the cabin.

There are only two ways to get significantly better gas mileage with your current vehicle: Drive less and slow way down, neither of which you'll likely do until gas gets to about $8 a gallon.

Obviously, if turning on the air conditioner is visibly and immediately affecting the car’s operation, turn it off — you don’t want your engine overheating, for example. But assume for the moment that your car is fine and that you’re not limping your way to the nearest gas station, trying to preserve what you have left in the gas tank.
