• Check your tires. Under inflated tires require more energy to move the car, which wastes fuel. Check the tire pressure at least once a month, when tires are cold. Being under inflated by just 2 psi can increase fuel use. Replace worn tires with the same make and model tires as were on your car when it was new.
• Get a tune up. Maintaining your car with regular tune ups can save you money. A clogged air filter alone can rob fuel efficiency.
• Buy vehicles with excellent gas mileage, and drive your most fuel efficient vehicle whenever possible.
• Follow the manufacturer's recommendations for preventative maintenance.
