Fuel Efficiency
10 Summer Driving Tips to Improve Gas Mileage
With gas prices creeping up again, consumers want to do everything possible to get the best gas mileage and performance out of their vehicle. Additech and Joe Gibbs Racing champion crew chief Greg Zipadelli have 10 expert tips to help consumers improve fuel efficiency:
1. Check tire pressure and inspect tires for uneven tread wear. Driving with under inflated tires is like driving with the parking brake on and can cause a loss in fuel efficiency up to two miles per gallon.
2. Change air filter regularly. An air filter that is clogged wastes gas and causes the engine to lose power causing a decrease in fuel efficiency of up to two miles per gallon.
3. Replace worn spark plugs as recommended by the vehicle manufacturer. Dirty spark plugs cause misfiring, which wastes fuel.
4. Use quality fuel and oil and change your oil and oil filter every 3,000 miles. Dirty or substandard engine oil increases internal engine friction.
5. Remember to tighten gas cap with each refueling.
