Good Maintenance for Good Mileage

You can significantly cut back on your fuel consumption by keeping your vehicles in good running condition.

Keeping the engine properly tuned is important. Repairing an engine that is badly out of tune or that has failed its emissions test will improve its gas mileage by about 4 percent, depending on the type of repair and how well it was done.

Fixing a serious problem, such as a faulty oxygen sensor, can improve a car’s gas mileage by as much as 40 percent.

The air filter keeps dust and other impurities from damaging a car’s engine. It should be checked regularly. Replacing a clogged air filter can improve gas mileage by about 10 percent. Replacing a dirty air filter will not only save gas, but protect the engine.

Properly inflated tires last longer, are safer, and improve gas mileage by about 3.3 percent. Under-inflated tires lower gas mileage by about 0.4 percent for every 1 psi drop in pressure in all four tires.

By using the grade of motor oil recommended by the manufacturer, you can improve your gas mileage by 1 to 2 percent. Conversely, for example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1 to 2 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1 to 1.5 percent. Also, select motor oil that says “Energy Conserving” on the API performance symbol. This means that it contains friction-reducing additives.
