WRONG! Mythbusters busted that myth. Both having the A/c and windows down burn the same amount of gas.

sorry but i have to say this. yea Mythbusters busted that myth but that link that was sent proving that they did is fine but you have to read it or know some things about cars. A. you can build 1000 engines using exactly the same castings and parts to build them and have them all be different. B. they used 2 different vehicles to bust that myth. if the one for what ever was getting 1/4 mpg less that would make the results bogus because that was their constant. C. they did it on a circle track if for whatever reason one of them drifted 1 foot up the track they actually went farther then the other person so counting laps doesnt work. D. If you actually watched that episode they drained "all" the fuel out of the vehicles and put in "5" gallons. what if they didnt actually get all the fuel out of the tanks and the one actually had more in it?
Bottom line here is that episode had so many things wrong with the way they did things.
If i am driving normally in my 96 gs with the ac on or with it off i can get approx the same fuel mileage on the highway regardless.
