Use the Recommended Grade of Motor Oil

You can improve your gas mileage by 1-2 percent by using the manufacturer’s recommended grade of 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 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1-1.5 percent. Also, look for motor oil that says “Energy Conserving” on the API performance symbol to be sure it contains friction-reducing additives.
  Fuel Economy Benefit:
1-2%
  Equivalent Gasoline Savings:

Note: Cost savings are based on an assumed fuel price of $3.22/gallon.
