Proper car maintenance can extend the life of your car, but did you know it can also impact your car’s fuel efficiency? Here are a few helpful tips to keep in mind.
  • Fix any problems right away to improve gas mileage

    Fix any problems right away

    Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4%, though results vary. Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40%.††

  • Check tire pressure, to increase fuel efficiency by up to 3%

    Check tire pressure

    Checking and adjusting the pressure of your tires once a month can increase a car’s fuel efficiency by up to 3%.††

  • Gear up, higher gears are more economical in terms of fuel consumption

    Gear up

    Get into the habit of shifting up to a higher gear as soon as you can. Higher gears are more economical in terms of fuel consumption. ††

  • Upgrade your motor oil to improve gas mileage up to 1–2%

    Upgrade your motor oil

    You can improve your gas mileage by 1–2% by upgrading the manufacturer’s recommended motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1–2%. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1–1.5%. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives. ††

  • Change air filters to improve fuel economy and acceleration

    Change air filters

    Replacing a clogged air filter on an older vehicle with a carbureted engine can improve both fuel economy and acceleration by a few percentage points under normal replacement conditions. †† Replacing a clogged air filter on vehicles with fuel-injected, computer-controlled gasoline engines — such as those manufactured from the early 1980s to the present — or diesel engines does not improve fuel economy, but it can improve acceleration.††
