    So it's true that it's efficient to use A/C on highway than windows down right? I heard cause there's grater resistance from wind.. with windows down.. it's less efficient. not by how much though.

    No way!! Guess I should use AC more often if it's true....

    Under highway speed, windows down was better. At or over highway speed, A/C is better. Obviously driving style also affects things...same as what else might affect drag/wind resistance.

    LOL! that's so funny, i do that too! I do it because A/C makes me nauseaus, (I think i may be allergic to freon), but sometimes you just need something cool - esp if it's really humid.

    Actually, you wouldn't come into contact with freon. It's a sealed system, and the cool air wouldn't have any freon in it. Unless of course you have a leak. Then you wouldn't have cold air for long.

    Lets put it this way. I'm driving on the highway at about 113km/h... I know it is not all accurate, I was getting about 5.1L/100KM (With fan speed at 1, windows up), my brother complained it was too hot so I turned on the AC (fan speed at 1 with full re-circulation), it jumped to 6.4L/100KM.

    So for Phil's car, if he has his windows up and use the fan, he'll get better mileage than those of us with the window up and use AC...

    as for AC an windows down comparison, I have no idea.

    This is the dilema I face, windows open, sunroof open, or A/C?
