10 Energy saving tips for your car
 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.
