Gas prices are zooming sky high with no ceiling in sight. Do you remember when a gallon of unleaded cost $1.25?

These days, it's more important than ever to stretch your dollars at the gas pump.

Here are ten gasoline buying tips to help you do that.

1. Shop Around

Prices vary among stations that sell the same brand. Find a station that sells your favorite brand cheaper. Prices between brands can vary. You can save money by switching brands.

2. Use a Gasoline Credit Card

Some give a 5 to 10 percent rebate on purchases.

3. Buy Gasoline in the Morning

Gasoline is denser during the morning when temperatures are colder. Gas pumps measure and charge by volume, not density. You'll be getting more solid fuel rather than vapors for your money.

4. Buy Gas from a Busy Station

Busy gas stations refill their underground tanks often. Slower stations don't. Therefore, their tanks may have stale contaminated gas. Older fuel is poorer on fuel economy and performance.

5. Turn the Nozzle

Twist the gas pump nozzle 180 degrees when done. This can add up to an extra four ounces to your tank.
