How to get better mileage
There are steps you can take to make an old car, truck or SUV perform better, go farther and perhaps save some money on fuel:
● Make sure there’s enough air in the tires. Underinflated tires create more rolling resistance with the pavement, thereby reducing gas mileage. Inflate your tires to the pressure recommended on the inside of your driver’s side door. Check them periodically with a tire pressure gauge.
● Properly maintain your vehicle. Follow the manufacturer’s recommendations for oil and other fluid changes and for replacing air and other filters. Replacing spark plugs at the proper intervals can help, too.
● Watch your speed. AAA says fuel economy peaks around 50 miles per hour on most vehicles, then drops as
speed rises. Reducing highway speeds by 5 mph to 10 mph improves gas mileage by up to 14%.
● Plan your route in advance. Try to minimize backtracking. Do multiple tasks on each trip. Avoid rush hours and other peak travel times.
● Don’t idle too much. An engine burns one-quarter to a half-gallon of gas per hour when idling, but a warm engine needs only around 10 seconds worth of fuel to restart, according to AAA. So when safely possible, shut your engine off if you’ll be stopped for more than a minute. Many new vehicles do this on their own.
● Coast to stop lights. Time your travel to keep rolling and avoid unnecessary stops. Cars consume a lot of fuel to get moving from a dead stop.
● Fill up with gasoline designated as “Top Tier.” Oil companies put additives in Top Tier gas that cuts carbon
deposits.
