Gas prices getting you down? Complete this checklist to improve your overall gas mileage by at least 10%.

—-

3% – Keep your tires properly inflated. “Under-inflated tires can lower gas mileage by 0.3 percent for every 1 psi drop in pressure of all four tires.”

1-2% - Use the recommended motor oil for your car. “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.”

5% – Slow down when accelerating and drive less aggressively. “For a typical family sedan…it appears that aggressive driving at city speeds causes a 6% fuel economy penalty.”

Bonus:

6% – (estimated) Keep your emissions as low as possible and get car repairs done promptly. While the study results were pretty conclusive, the data wasn’t recorded properly. However, based on this data lowering fuel emissions and keeping your car in proper running condition will greatly increase fuel economy.
