Nothing says summer like a road trip to one of Maine’s storied state parks, coastal beaches or mountain lakes.

While gas prices are on the rise nationwide just as you’re scheduling those final outings of the season, the Maine Department of Environmental Protection has simple steps to help you save fuel and funds while prolonging the life of your vehicle and reducing air pollution.

* Avoid idling. Idling can use a quarter to a half-gallon of fuel per hour, depending on engine size and air conditioner use. Avoid idling your engine longer than 30 seconds.

Idling for more than just 10 seconds actually uses more gas than shutting the engine off and restarting.

* Drive sensibly and observe the speed limit. Aggressive driving including speeding, rapid acceleration and braking can lower your gas mileage by 33 percent at highway speeds and 5 percent around town.

Observing the speed limits set by the state isn’t just the law; it’s also good for your gas mileage, which decreases rapidly at speeds higher than 60 mph.

Each 5 mph you drive above 60 mph is like paying an additional 30 cents per gallon of gas.

Using cruise control on the highway helps you maintain a constant speed and saves gas. When you use overdrive gearing, your vehicle’s engine speed goes down which also improves fuel economy.

* Minimize drag. Driving with the windows open, using roof or rear mounted racks and carrying heavy loads increases vehicle drag. Avoid keeping unnecessary items in your vehicle. An extra 100 pounds in your vehicle could reduce your miles per gallon by up to 2 percent.

* Keep tires inflated. You can improve your gas mileage by more than 3 percent by keeping your tires aligned and inflated to the proper pressure. Properly inflated tires are safer and last longer. The proper tire pressure for your vehicle is usually found on a sticker in the driver’s side door jamb or the glove box and in your owner’s manual.

Do not use the maximum pressure printed on the tire’s sidewall.

* Tune-up. Get regular engine tune-ups and vehicle maintenance checks (especially for the spark plugs).

Don’t ignore the “check engine” or “service engine soon” light if it comes on; make an appointment with your repair technician.

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 percent, and fixing a serious maintenance problem, such as a faulty oxygen sensor can improve your mileage by as much as 40 percent.
