More top tips to help you save gas this summer

Fight skyrocketing gas prices by taking control of your vehicle's unnecessary fuel consumption. As fuel prices continue to rise, there are some easy maintenance tips that can help make the most of your gallon and save money down the road.

The first one is easy. Use the number on the sticker in your doorjamb, or inside the gas door. This is the proper pressure for your year make and model. Always check tire pressures in the morning when the tires are cold. Save as much as two miles to the gallon by having the correct pressure.

Another way to save 10 percent on your fuel economy is by changing your air filter regularly. It should cost about $5 to $20 for a new filter that will help your car run more smoothly. While you're under the hood, check your spark plugs as well.

Spark plugs are something people don't think about. Their job is to create a spark inside the engine to burn the fuel. If one of them is not functioning properly, you can waste a lot of additional fuel, so check your plugs every six months.

One way to make the most of your gallon is by checking the gas cap. Make sure it is on tight. Believe it or not, last year, 147 million gallons of gas evaporated because people didn't use their gas caps properly.

Even though it's cheaper, it's not a good idea to try to save money by downgrading to a lower octane gas. For the best fuel economy, use the gas that is recommended for your vehicle by the manufacturer.

Do not drive aggressively. Aggressive driving can lower gas mileage by as much as 33 percent on the highway and 5 percent on city streets, which results in 10 to 66 cents per gallon. When that light turns green, it's not a drag race. Every time you step on the gas really hard, you are wasting fuel.

Use your cruise ... and observe the speed limit. Gas mileage decreases rapidly at speeds above 60 mph. Each mpg driven over 60 will result in an additional 10 cents per gallon. To maintain a constant speed on the highway, cruise control is recommended.
