I've always heard it was more economical to use the A/C as opposed to driving without it if you end up opening your windows...I heard the extra "drag" from the open vehicle is equal to or greater than the amount of economy you'd lose running A/C...sound right? Or should that tidbit of info be filed near the "Tornado Fuel Saver"? <img src="/forums/images/graemlins/lol.gif" alt="" />
