Drive Smart!
A well-tuned car with properly inflated tires burns less gasoline—cutting pollution and saving you money at the pump. If you have two cars, drive the one with better gas mileage whenever possible. Better yet, skip the drive and take public transit, walk, or bicycle when you can

Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline, it can lower your highway gas mileage 33% and city mileage 5%.

Consider buying a highly fuel-efficient vehicle. A fuel-efficient vehicle, a hybrid vehicle, or an alternative fuel vehicle could save you a lot at the gas pump and help the environment.

Combine errands into one trip. Several short trips, each one taken from a cold start, can use twice as much fuel as one trip covering the same distance when the engine is warm.

Get regular engine tune-ups. Replacing clogged air filters can improve gas mileage by as much as 10% and protect your engine.

Keep tires properly inflated and aligned to improve your gasoline mileage by around 3%.

Use the grade of motor oil recommended by your car's manufacturer. Using a different motor oil can lower your gasoline mileage by 2%.

Consider telecommuting, carpooling and public transit to cut mileage and car maintenance costs.

Reduce drag by placing items inside the car or trunk rather than on roof racks. A loaded roof rack can decrease your fuel economy by 5%.

Clear out your car; extra weight decreases gas mileage.

Use air conditioning only when necessary, consider opening a window instead.
