NBC NATIONAL NEWS — With sky high gas prices, we're all looking for ways to save at the pump.
There are even gadgets and gizmos that promise to bump up gas mileage, but before you waste your time and your money trying to save a few pennies it's important to separate fact from fiction.
The folks at AAA have a facility that tests devices that claim they can improve your mileage.
They say for the most part gadgets you attach to your car or install in the air lines simply do not work.
"We haven't found a device that works the way it's purported to work," says AAA's Jeffrey Spring.
They also discount the myth that the time of day you fill your tank can make a difference on the amount of fuel you actually get.
Experts say gas station tanks are so far underground that fuel temperature will not matter.
AAA also says that turning off your air conditioner or obsessing over a clean air filter won't make much of a difference in modern cars.
So what are four tips aren't bogus?
#1 - Keep that lead foot off the pedal. Sensible acceleration saves fuel.
#2 - Have a qualified mechanic check your engine.
#3 - Stop buying more expensive, higher octane fuel. Most cars don't need it.
#4 - If you gas up near a freeway entrance, you're probably paying a little extra.
"Just go down a couple blocks and you'll probably see cheaper gasoline," Spring advises.
