A friend told me this. You can leave your windows down up to about 50mph. After that raise them up and use your a/c.
Why? I asked him.
Because the wind resistance of the wind going into the car and pushing against it and still trying to maintain your 55mph speed uses more gas then using your a/c at 55mph.
Thought he was da man!
That's true for the most part.
However, even better mileage with windows up and no A/C on
