With the price of a gallon of gas uncomfortable close to — and in some cases topping –$4, almost everyone is looking for ways to squeeze an extra mile out of a tankful.
Slow down on highways
Most vehicles reach peak fuel efficiency at speeds between 45 and 55 miles per hour. According to U.S. Department of Energy (DOE) figures, you lose 7 to 23 percent of fuel efficiency for every five miles per hour in excess of 60 MPH. Some drivers might save a gallon of gas a week this way.
Keep calm and close the windows
DOE says aggressive driving (including rapid acceleration and hard braking as well as speeding) wastes gas. Driving aggressively can lower your highway gas mileage 33 percent and city mileage 5 percent. Using cruise control is one way to smooth out mileage. If you can, schedule your driving to avoid peak rush hours. Driving down the highway with your windows open also creates drag, and lowers mileage.
Keep tires properly inflated
You can improve your gas mileage up to 3.3 percent by keeping your tires at the recommended air pressure, the federal Website fueleconomy.gov says. The savings may not be big, but you’ll be making your car safer and helping your tires last longer. The proper tire pressure for your vehicle is usually found on a sticker in the driver’s side doorjamb or the glove box and owner’s manual. Do not use the maximum pressure printed on the tire’s sidewall.
Turn the engine off
Picking someone up? Held up at a railroad crossing? Shut off your engine and conserve fuel. You’ll be saving money and doing the environment a favor.
Remove needless weight
“Carrying 100 extra pounds in your vehicle could reduce your gas mileage by 1 to 2 percent,” according to DOE. If you haven’t bothered to look in your trunk or under the seats lately, it might be a real pay-off to spend a few minutes removing all unnecessary items.
Keep up with maintenance
Tuning up your vehicle regularly can boost gas mileage by an average of four percent, according to fueleconomy.gov. Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.
It is suggested not to pump gas from 9 a.m. to 4 p.m. when a “red” air quality alert has been announced. When you’re finished pumping, be sure the cap is screwed on tight.
By shifting from driving alone to ride-sharing with someone else, you may cut costs by more than half. Choosing this option can be your entry pass to a faster high occupancy vehicle (HOV) lane on the highway. Several websites exist to help potential carpoolers in the same area connect. Talk to co-workers already using a carpool and find out how they did it, and how they like it.
Combining several errands into one trip, whether business or personal, can payoff in lower gas bills. Several short trips, each from a cold start, can double your fuel-use compared with a single trip covering the same distance when the engine is warm. Bicycling, telecommuting or using public transit can eliminate a car commute to and from work.
