How to Use Less Gas


Even without buying a new car, you can cut your gas use greatly by driving smartly and maintaining your vehicle well. See suggestions from US DOE and EPA below:

  • Drive Sensibly
    Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, so you may save more than gas money.
    Fuel Economy Benefit: 5% to 33%
    Equivalent Gas Savings:19¢ to $1.26 per gallon.
  • Observe the Speed Limit
    Gas mileage decreases rapidly at speeds above 60 mph (miles per hour). Each 5 mph you drive over 60 mph increases gas use by 5% to 10%. Observing the speed limit is also safer.
    Fuel Economy Benefit: 7% to 23%
    Equivalent Gas Savings:26¢ to 86¢ per gallon.
     Slow down and save!
  • Avoid Excessive Idling
    Sitting in traffic, or idling, wastes gas. Cars with larger engines typically waste more gas idling than cars with smaller engines.
  • Inflate Your Tires Properly
    Under-inflated tires can reduce gas mileage by several percent. Check your owner's manual for the recommended tire pressure.
    Fuel Economy Benefit: up to 3%
    Equivalent Gas Savings: up to 11¢ per gallon.
  • Use Cruise Control
    Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.
  • Maintain Your Car Well
    Routine maintenance and repair can improve gas mileage, though results vary based on the kind of repair and how well it is done. Fixing a faulty oxygen sensor may improve your gas mileage as much as 40 percent.
    Fuel Economy Benefit: 4%
    Equivalent Gas Savings: up to 15¢ per gallon.
  • Buy the Most Fuel-Efficient Vehicle That Meets Your Needs
    Make fuel economy part of deciding what car to buy or rent. Go to US EPA's website (www.fueleconomy.gov) for miles per gallon ratings on all vehicles.
