Tips for saving money on gas  

1. Find a bargain.

If you're taking a summer road trip, plan out your route before you go. Identify gas stations along the way that have the lowest prices.

When I stopped in a beach town last week to fill up my car I didn't plan like I should have (I almost ran out of gas), and it cost me the most I'd ever paid for gas -- $3.85 a gallon. Next time I'll go to GasBuddy.com, a site that lets consumers share gas price information easily, and find a better deal before I head for the beach.

2. Keep your tires fully inflated.

The U.S. Department of Energy reports that the average driver can improve mileage by 3.3 percent simply by inflating their vehicle's tires regularly.

In fact, according to the AAA, under-inflated tires are the No. 1 way we waste gas. One out of every four cars and one out of every three pickups, vans, and SUVs have at least one extremely low tire. So pick up a tire gauge at your local auto parts store and check your tire pressure whenever you pull into a service station for gas. Your car's owner's manual will tell you the recommended PSI -- pounds per square inch -- rating.

3. Get a tune-up.

A vehicle in need of servicing is wasting gas in more ways than one. According to the Department of Energy, replacing a clogged air filter can improve your gas mileage by 10 percent, while fixing a faulty oxygen sensor can improve gas mileage by an unbelievable 40 percent.

So kick off your summer by getting that tune-up you've been putting off. Check your owner's manual, or download a free service and maintenance schedule at CarCare.org.
