Automobile Energy Saving Tips

  • Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline.
  • Consider buying a highly fuel-efficient vehicle. A fuel-efficient vehicle, a hybrid vehicle, or an alternative fuel vehicle could save you a lot at the gas pump and help the environment. See the Fuel Economy Guide for more on buying a new fuel-efficient car or truck.
  • Combine errands into one trip. Several short trips, each one taken from a cold start, can use twice as much fuel as one trip covering the same distance when the engine is warm.
  • Replace clogged air filters to improve gas mileage by as much as 10% and protect your engine.
  • Get regular engine tune-ups and car maintenance checks to avoid fuel economy problems due to worn spark plugs, dragging brakes, low transmission fluid, or transmission problems.
  • Keep tires properly inflated and aligned to improve your gasoline mileage by around 3.3%. Also, switch to radial tires as they reduce friction and can gain from 5%-7% additional fuel mileage.
  • Use the grade of motor oil recommended by your car's manufacturer. Using different motor oil can lower your gasoline mileage by 1%-2%. Additionally, change your oil frequently and keep fuel filters changed and clean.
  • Check into telecommuting, carpooling and public transit to cut mileage and car maintenance costs.
  • Reduce drag by placing items inside the car or trunk rather than on roof racks. A roof rack or carrier provides additional cargo space and may allow you to buy a smaller car. However, a loaded roof rack can decrease your fuel economy by 5%.
  • Clear out your car; extra weight decreases gas mileage.
  • Use air conditioning only when necessary.
  • Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.
  • When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces wear.
  • Avoid high speeds. Above 60 mph, gas mileage drops rapidly. The Fuel Economy Guide website shows how driving speed affects gas mileage.
  • Aggressive driving (speeding, rapid acceleration, and hard braking) wastes gas. It can lower your highway gas mileage 33% and city mileage 5%.
  • Idling gets you 0 miles per gallon. The best way to warm up a vehicle is to drive it. No more than 30 seconds of idling on winter days is needed. Anything more simply wastes fuel and increases emissions.
