Car Maintenance Tips
• Use the grade of motor oil your car’s manufacturer recommends. Using a different motor oil can lower your gas mileage by 1%-2%.
• Inflate your tires to the pressure listed in your owner’s manual or on a sticker in the glove box or driver’s side door jamb. This number may differ from the maximum pressure listed on your tire’s sidewall.
• Get regular maintenance checks to avoid fuel economy problems due to worn spark plugs, dragging brakes, sagging belts, low transmission fluid, or transmission problems.
• Don’t ignore the check-engine light—it can alert you to problems that affect fuel economy as well as more serious problems, even when your vehicle seems to be running fine.
• Replace clogged air filters on an older car with a carbureted engine to improve gas mileage by as much as 10% and to protect your engine.
Long-Term Savings Tips
Choose vehicles according to your need. For example, if you mostly drive in cities, a smaller hybrid might be right for you because they get better mileage in city driving and are easier to park.
If you need a vehicle for towing or heavy use, consider a clean diesel vehicle. Diesel engines are quieter, more powerful, and 30%-35% more efficient than similar-sized gasoline engines. The new generation of clean diesel vehicles must meet the same emissions standards as gasoline vehicles.
Many vehicles produced by U.S. auto manufacturers are flexible fuel vehicles (FFVs), which can run on E85 (85% ethanol, 15% gasoline) and other ethanol-gasoline blends. Check your owner’s manual to find out if your vehicle is an FFV.
Consider buying a highly fuel-efficient vehicle. A fuel-efficient, plug-in electric (PHEV), hybrid, or alternative fuel vehicle could cut your fuel costs and help the environment.
