• Keep Tires Properly Inflated
You can improve your gas mileage by around 3.3 percent by keeping
your tires inflated to the proper pressure. Under-inflated tires
can lower gas mileage by 0.4 percent for every 1 psi drop in pressure
of all four tires. Properly inflated tires are safer and last
longer.

• 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.
