    So rumor says vehicles use more gas to have Windows down on freeway due to the extra drag. I'm wondering if anybody with scanguage can confirm if it trully uses more gas then running the AC? Thanks

    I guess there is a bigtime difference between one driver window cracked half way and both windows all the way down.

    I say 'who cares!?' I drive with all the windows down, all the time, on the highway and off; even during the winter when the temp permits

    Mythbusters, a teevee show, did an experiment to see what uses more gasoline. I believe they found it doesn't matter but YMMV.

    I saw this on mythbusters, and from what I remember if you are going over 40 (obviously you are on a freeway) you save gas using the a/c

    I just googled the episode and your right they did find that windows up & a/c gave better fuel economy per the computers but when they actually ran the cars on 5 gallons of fuel, the windows down & a/c off ran farther than the a/c. I think the right foot has more to do with it than anything else.

    I think this is the answer!
    I run windows up and A/C on...... and get over 20 consistantly in the summer. My winter mileage is what goes down.
