It's no secret. The price for a gallon of gas is reaching levels most of you probably never thought you'd see. Everyone's got a theory on how to save gas, but not all of them work.
There are plenty of legitimate ways to reduce your car's fuel consumption: drive slower, carpool, maybe bike to where you need to go.
All those are well and good, but what about they theories you think will work, but don't.
Turning off the air conditioner when driving. The a/c does reduce your fuel use, but Consumer Reports says only by maybe a mile. And the drag created from driving with your windows down can reduce your fuel efficiency by the same amount.
Avoid those gas saver additives you see in the stores or on TV. Tests have been done on these things and none have been shown to help your gasoline use.

Well, these days, tanks are buried deep enough that the temperature difference between the colder part of the day and the warmest is so small, you'll only save a few cents.
