AC question!!! Which saves more gas?!?!

christian370z

I try my hardest not to use the A/C unless I really have to or have a passenger in the car. One trick you can use is if you really need the A/C, try lowering one of the windows slightly. This creates a negative pressure area that actually draws air out of the car which in turn pulls more air through the air con system.

It adds the same amount of extra air as using one additional fan speed, not bad! The higher the fan speed, the more current the system is drawing which means more load on the engine.
