A Myth of Saving Gas And Ways

Do you think it's more fuel efficient to roll down the windows, or to close them and turn on the Air Conditioner? Most people will think closing the windows will do the trick, but no. Although the air resistance will decrease, the A/C will make the engine have to do more work, so the car would have to use more gas. Keeping sunroof open and windows closed is also wasteful because the air will not be able to get out.
Basics
1. Keep tires inflated (be sure not to over inflate or tires will actually pop)
2. Take Junk out of your trunk.
3. Take everything off the roof.
4. Close convertible tops.
5. Turn off the engine at short stops. (Except traffic lights of course)(Except when engine is hot)(Except GM hybrids)
