Ways To Improve Gas Mileage
Slow Down - Gas mileage efficiency decreases at speeds over 50 mph.
Use Cruise Control When Appropriate - According to Edmunds.com, using cruise control under appropriate conditions can improve fuel economy by up to 14%. Be smart about it, cruise control is most efficient on flat highways, rather than hilly areas.
Drive Smoothly - Try to drive as smoothly as possible. Speedy acceleration, jerky braking and stop-and-go traffic waste gas. Studies suggest that poor driving habits can affect fuel economy by between 15% and 30%.
Limit Idling - Idling uses more fuel than restarting your car and gives off 80% more pollution than when your car is in motion. The next time you come to a stop and are waiting for someone, consider turning off your engine to save fuel.
Check Tire Pressure - Tires can lose about 2 pounds per square inch (psi) per month, even new tires on a new vehicle. Each tire that is underinflated by 10 psi reduces fuel economy by about 3.3%. Four tires that are underinflated by 10 psi would reduce a vehicle's fuel economy by 10%, that's significant. Check your owner’s manual or the tire wall for the correct PSI for your tires. Low pressure also causes premature tire wear, so you're saving on two fronts.
Keep Windows Closed - Your vehicle's fuel efficiency has a lot to do with aerodynamics. Even partly opened windows will reduce aerodynamics and waste gas due to increased drag. Contrary to popular belief, you'll save more fuel with the windows up and the air conditioner turned on during warm weather.
Reduce Extra Weight - Trucks are meant for hauling, but when you're using your vehicle as rolling storage, that extra weight can cut down on fuel economy. If you're keeping extra sports equipment, tools or other larger, heavier items in your truck that you don't use everyday, consider storing them in your garage to save fuel.
