Maximum gas-saving tip: If you see a tanker truck at your local gas station filling up their reserves, keep driving right on by. Filling up your tank as the main reserve fills up can lead to an unknown mixture of gasoline and sediment that's being stirred up by the tanker truck. Dirt, debris and other unwanted material could end up in your gas tank.

Maximum gas-saving tip: Fill up in the morning or late at night, not during the day when it's warmest. When gasoline is cool, it is densest; when it gets warmer, gasoline expands and fills up your tank more quickly, while delivering less actual gasoline to your car.

Maximum gas-saving tip: The best time to fill up on gas is when it's half-full, not when you're close to empty. When there is less air in the gas tank, less gasoline will evaporate as you fill up. And as always, make sure you click the gas cap at least 3 times to make sure no gas escapes after you've filled up.
