(BPT) - Did you know it's possible to save hundreds of dollars a year when it comes to automotive expenses? You can save money and keep your car running longer by doing a little research and by upgrading some of the car care products you already buy.

Here are some easy tips for you to keep your car running great while keeping more money in your pocket:

Worth the upgrade

Improve your car's fuel economy and engine life by upgrading to high performance synthetic motor oil like Royal Purple. Studies have shown that Royal Purple motor oil may improve fuel economy by as much as 5 percent and can significantly reduce engine wear. When compared to conventional motor oils, premium synthetic oils will allow you to go more miles between oil changes, reducing maintenance costs and time spent in the shop.

Keep your tires inflated

Improve your gas mileage by keeping your tires properly inflated. The U.S. Energy Department reports that 50 to 80 percent of the tires traveling on U.S. roads are underinflated which can increase fuel consumption by up to 3 percent. Make sure you inflate the tires to the manufacturer's recommended tire pressure and not by the number on the sidewall of the tire. Tires are produced to fit a broad range of vehicles, but manufacturers spec tire pressures that are specific to the car's components. For more fuel savings tips visit www.fueleconomy.gov.

Tune it up

Check your manufacturer's manual for the recommended tune up interval, but the general recommendation is two years or 30,000 miles depending on conditions such as extreme temperatures, weather and use of the vehicle. A tune up can include replacement of the fuel filter if applicable, changing the spark plugs, and replacing worn belts. Scheduling recommended tune ups is an important step in preventative vehicle maintenance that will make sure the vehicle gets the best gas mileage possible and will uncover problems before they become expensive to repair.

Get a quote

Take advantage of insurance companies that offer free quotes for your auto insurance. Prices can vary from company to company, so it pays to do a little research. Obtain at least three price quotes by using the Internet or calling an insurance agent directly. Have your current policy and coverage in front of you so you can compare the quotes you receive for the best value.
