KEEPING YOUR VEHICLE IN SHAPE!

1. KEEPING YOUR ENGINE PROPERLY TUNED - Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4.1 percent, though results vary based on the kind of repair and how well it is done. If your car has a faulty oxygen sensor, your gas mileage may improve as much as 40 percent.

Fuel Economy Benefit: 4 - 40% Equivalent Gasoline Savings: $0.06 - $0.60/gallon

2. CHECK & REPLACE AIR FILTERS REGULARLY - Replacing a clogged air filter can improve your car's gas mileage by as much as 10 percent. Your car's 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.

Fuel Economy Benefit: up to 10% Equivalent Gasoline Savings: up to $0.15/gallon

3. KEEP TIRES PROPERLY INFLATED - You can improve your gas mileage by around 3.3 percent by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by 0.4 percent for every 1 psi drop in pressure of all four tires. Properly inflated tires are safer and last longer.

Fuel Economy Benefit: up to 3% Equivalent Gasoline Savings: up to $0.05/gallon

DRIVE MORE EFFICIENTLY!

1. DRIVE SENSIBLY - Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and 5 percent around town. Sensible driving is also safer for you and others, so you may save more than gas money.

Fuel Economy Benefit: 5-33% Equivalent Gasoline Savings: $0.07 - $0.49/gallon

2. OBSERVE THE SPEED LIMIT - Gas mileage decreases rapidly at speeds above 60 mph. Each 5 mph you drive over 60 mph is like paying an additional $0.10 per gallon for gas. Observing the speed limit is also safer.

Fuel Economy Benefit: 7 - 23% Equivalent Gasoline Savings: $0.10 - $0.34/gallon

3. AVOID EXCESSIVE IDLING - Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

4. USE CRUISE CONTROL - Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.

5. USE OVERDRIVE GEARS - When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.

6. MINIMIZE THE USE OF YOUR AIR CONDITIONING - To stay cool at highway speeds, use your car's flow-through ventilation. When driving in the city, open a window.
