Gas Saving Tips Use snow tires only during winter season. Deep treads use extra fuel. Stop filling your gas tank on the first "click-off" of the nozzle. Overfilling can slosh fuel out of the tank. Travel the speed limit in areas where traffic lights are "timed", to increase your chances of getting green lights. Use cruise control to achieve steady driving speed. Limit engine warm up time. Buy gas at less expensive self-serve pumps. Check trunk and remove unnecessary weight such as extra tires. Weight reduces mileage. Replace dirty air filters. Try gas at the lowest octane level recommended in your owner's manual. Premium costs more than regular. Avoid unnecessary idling. One minute of idling can use as much fuel as re-starting the engine. Eliminate revving the engine just before you switch the engine off. Accelerate slowly when starting from dead stop. Car pool. Buy gasoline during coolest times of the day when density is highest. You get more for your money. Replace bad shocks, broken springs and bent wheels to eliminate engine drag. Cut driving speed when possible. Faster travel means the vehicle has to overcome more wind resistance and affects gas mileage. Driving 55 mph instead of 65 mph on interstates can improve gas mileage 15% or more. Pay cash if the station charges more for credit cards. Traveling at higher speeds in low gears on a "stick shift" can use more fuel than necessary. Keep windows closed when traveling at highway speeds. Open windows cause air drag, reducing mileage. "Even" driving can improve mileage. Constant slowing and speeding up wastes fuel. Avoid tailgating for more than safety. If the driver in front slows or stops unexpectedly, your fuel economy is affected. Anticipate the need to accelerate. Pick up speed before a hill, not when you are on it. Avoid riding the brake. "Drag" not only causes early replacement, but requires more fuel use. Choose smooth paved roads over rough dirt or gravel roads, when possible, for better mileage. Park your car so you can leave in "drive" rather than "reverse". Changing gears takes more gas. Follow owner's manual for recommended maintenance, including tune-ups. Keep tires properly inflated. Combine several short trips for errands into one trip.
