Monitor Your Tires
Under-inflation causes tires to wear out faster and wastes gas. Properly inflated tires reduce friction and offer better gas mileage.
However, temperature changes can cause tire pressure to fluctuate by as much as two to three pounds per square inch (psi), so be sure to check the psi regularly – especially during seasons when the weather shifts drastically. You may also want to contact your car dealer to see if they offer free tire pressure check-ups.
Also, if you utilize snow tires during the winter months, be sure to replace them in the spring. Snow tires cause excess friction on dry surfaces, wasting gas.
Tune the Engine
Car engines need to be regularly tuned. A properly tuned engine uses less gas, so if you can’t remember when you last had a tune-up, it may be time to schedule one.
Check your filters regularly – especially if you live in a dusty area. Clean filters help to keep cars running more fuel efficiently.
Use the Correct Motor Oil
Be sure to use the proper motor oil. If you’re not sure which type your car requires, check the owner’s manual or do a search online. Using the wrong motor oil can cause the engine to work harder and waste gas.
Turn Off the A/C
As much as you may love air conditioning, it turns your car into a gas-guzzler. Keep it turned off as much as possible. To keep your car cooler, park in the shade and roll the windows down a crack to circulate air.
