When the air is on in the car, are you using the same amount of gas whether the temp is high or low, or whether the fan is on high or lo? Or am I using the same amount of gas either way

The difference with the AC on or off is hardly noticable....maybe 1 mpg difference. The speed of the fan makes NO difference

ok, its a matter of blanace...... when using the a/c the compressor kicks in then pulling power from the engine.... so the lower the ac temp the longer the compressor is on. but... the same with the fan.... the higher the speed of the fan the more it pulls on the alternator. so if you set the air at 60 and the fan on low its going to use "x" amount of gas becasue its going to take longer to cool with the fan on low...... the air on 80 and the fan on high, is going to take the same "x" amount of fuel that yes you have reached the desired temp faster , the fan is still blasting. .... if your looking for a balance, do 70 on medium, if you are just looking for the physics.... there you go.

The mileage difference is so negligible you can't tell the difference. That's because the a/c is always turning, whether it is on or off, to begin with; so therefore the difference between setting it on high or low is even less noticeable.
The fan, too, draws so little extra electricity that the engine willn't notice any difference if the fan is on high, low or off! The alternator is always spinning (if it wasn't you'd have a dead battery), so again the difference is so slight as to be unnoticeable.

There is no real difference between running the fan on low or hi. theoretically, the faster the fan runs, the more energy it takes and your gas will go down slightly.
As long as the compressor is running, that is what will eat the most gas. It takes a lot of energy to turn the compressor and as long as its running, then you are losing gas mileage. good luck

It takes a slight amount of electrical power to run the fan on high, maybe a few cents worth of gas a month.

They use to say that a/c would cause your car to get less gas mileage. Now they are saying that there really is no discernible difference. Run the a/c or not, you get practically the same mileage.

you use more gas when on high, because the comp. has to work harder. Every little bit of energy saved is a step in the right direction. Why not just wind down the window!
