6.When traveling out of town, check prices. It may be much cheaper in your town or at your destination.
7.Don't use a higher octane than you need. 40 million drivers unnecessarily buy a premium grade. Look at the car manual or call the manufacturer's Customer Service Department to determine the correct grade.
8.If your car doesn't seem to run right, try a different brand of gas (same octane) before switching to a higher, more expensive grade. The additives in another brand of gas might work better with your car.
9.After filling up, turn the gas pump nozzle around 180 degrees to drain the last half cup of gasoline into your tank.
10.Don't fill your tank right up to the top. As much as one half gallon can leak out when the gas sloshes around during travel.
11.Don't get zero miles per gallon warming your car. Numerous experts recommend idling your car for only about a minute and then driving it slowly for a few minutes. This will greatly improve gas mileage and also lubricate the engine better.
12.Check tire pressure once a month. Correct pressure saves gas and and could save you 50% on the cost of tires as well.
13.Check your tires for uneven wear. Proper alignment saves gas and tires.
14.Replace the air filter regularly. A dirty filter will make the engine run too "rich."
15.Tune your car at least as often as specified by the manufacturer. Tune sooner in cold weather or if you drive in heavy traffic. A tune-up will more than pay for itself in gas savings.
16.Use an "energy conserving" oil, an EC or EC-II motor oil.
17.Remove any unnecessary weight from the vehicle. (When did you really take a good look at the stuff in your trunk?)
18.If you're not using the rack on top of your car, take it off. Wind drag reduces mileage.
19.Use the air conditioner only when necessary, especially in traffic. At highway speeds, however, the AC may be more efficient.
20.Driving 55 MPH will save 10%-15% vs. driving 65 MPH.
21.Drive smoothly. Fast starts, sudden stops, weaving in and out of traffic lowers mileage.
22.If you family has two cars, drive the car that's still warm for a quick errand. A cold engine gets terrible mileage -- about one third of a warm one.
