When driving: Windows down or AC?

[iambrutus]

Windows down, unless it is just aweful hot. I already get about 13 mpg's and don't want to make it worse if I don't have to.

GL, have you changed your stance since Mythbusters proved that AC doesn't impact gas mileage?

i almost always have my windows down and sunroof open playing music loud. i have yet to use my AC this year. the only time i use the AC is when i am sweating really bad on the way to the car and i need to dry off and/or it is blistering hot out which it hasn't been so far. i might keep them down just because my car is black with black leather so the inside of it is like an easy back oven when it is hot out. i keep my windows and sunroof open even if it is in the 40s too though so who knows. i never use the AC though. it might be because i am also paranoid of wasting the extra gas on any commute by having it on.......one of the many habits of being poor i guess.

Windows down, moon roof open. I usually don't resort to the AC unless I'm on the highway or the temp is creeping up into the high 90s.
