Drive at the speed limit. It is safer and more efficient. Gas mileage usually decreases rapidly at speeds above 60 mph. You can assume that each 5 mph you drive over 60 mph is like paying an additional $0.30 per gallon for gas.
Lighten your load. An extra 100 pounds in your vehicle could reduce your MPG by up to 2%. Remove unnecessary items and improve your vehicle’s efficiency.
Inflate car tires to the manufacturer's recommended levels. Under-inflated tires can cut fuel economy by 2 % per pound. Well inflated tires also ensure better braking.
Check and replace air filters regularly. Replacing a clogged air filter can improve your vehicle’s gas mileage by as much as 10%. The air filter keeps impurities from damaging the inside of your engine. Not only will replacing a dirty air filter save gas, it will protect your engine.
Don't warm up your car. Automatic transmissions do not need to be warmed and our sunny climate doesn’t really require a warmed vehicle. Remember that while warming your vehicle you are getting zero miles per gallon.
Make sure your gas cap is in good condition. If your gas cap is damaged, loose, or missing, your gas is evaporating and leaking into the air. 17% of vehicles have gas caps in poor condition, which accounts for 147 million gallons of wasted gas each year due to evaporation.
Plan before you drive. Think about all of the errands you need to take care of before you leave. One ride covering a half-dozen stops can cut out 5 additional trips.
