Everybody complains about gasoline prices. With the peak summer travel season approaching, that's only going to get worse. There's nothing you can do about gasoline prices, but there are several things you can do to make sure you get the most value for your dollar.

Some of them are widely known, such as making sure your tires are properly inflated, changing oil, air & oil filters at recommended intervals.
There are some lesser known tecniques for saving fuel, and seubsequently money. When you're on the highway, don't run "2/60 (2 windows down, 60 miles an hour) air conditioning." The aerodynamic drag of the open windows will cause your engine to work harder than it would with the windows up & the A/C turned on. Don't suck on the bottom of the tank. That's where impurities settle. Fill up when you're between 1/2 & 1/4 tank.
Did you know it makes a difference when and how you fuel up?
Cereal boxes typically have a disclaimer that reads, "This package is sold by weight, not volume." You're paying for X- number of ounces, not a full box. The reverse is true of gasoline. It's sold by volume, not weight. Temperature variances cause it to expand or contract more than most other fluids. Cold gasoline is denser than warm gasoline. You can get more gas into your tank during cool times of the day than in peak afternoon heat. Pump your gas slowly. The less turbulance inside your tank, the less space will be taken up by air & gasoline vapor. That being said, don't stop to fill up at a station while a tank truck is filling the underground tanks. These suggestions won't cut your fuel expense in half, but they will save you money.
