Improve your gas mileage

  • Lighten your load by clearing your car of extra weight, and remove roof racks or carriers if not used frequently.
  • Keep current with car maintenance—clean air filters can improve gas mileage by as much as 10%.
  • Properly inflated and aligned tires will improve gas mileage by 3%.
  • Using the wrong grade of oil can reduce mileage by 1% to 2%.
