• Aggressive driving (speeding, rapid acceleration, and hard braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by five percent around town.
• Avoid high speeds. Each five mph you drive over 60 mph is like paying an additional $0.10 per gallon for gas.
• Use air-conditioning only when necessary.
Car Maintenance Tips
• Keep tires properly inflated and aligned. Properly inflated tires can improve your gas mileage by around 3.3 percent.
• Get regular engine tune-ups and car maintenance checks. Replace clogged air filters-this can improve your car's gas mileage by as much as 10 percent, and it will also protect your engine. If your car has a faulty oxygen sensor, your gas mileage may improve by as much as 40 percent.
• Combine errands into one trip. Several short trips taken from a cold start can use twice as much fuel as a longer multipurpose trip.
$ Long-Term Savings Tip
• Consider a highly fuel-efficient vehicle for your next car, SUV, or truck purchase. Buying a standard vehicle, with high fuel efficiency, a hybrid vehicle, or an alternative-fuel vehicle for your next purchase, could save you a lot at the gas pump and help the planet at the same time. Vehicle emissions are a major source of U.S. air pollution today.
