From ‘US News & World Report, there are ways to save gas on this summer’s trips:
1. Get that "Check Engine" Light Checked Out:
A faulty oxygen sensor -- a fairly common cause of those unexplained "check engine" lights -- can actually cost you up to 40 percent of your engine's performance. If the light's on, make the appointment now. It could pay for itself very quickly.
2. Check Your Tire Pressure:
According to some government estimates, the average driver could boost their fuel efficiency by 25 percent just by keeping their tires inflated. That's often a free, or cheap, repair. On my way to work, I pass two gas stations with air compressors I can use for free, and three -- apparently owned by cheapskates -- that take quarters.
3. Change Your Air Filter:
Gas is half of the combustion equation. Air is the other half. A clogged air filter can rob 10 percent of your engine's efficiency. A new air filter can get that 10 percent back -- usually for under $15.
4. Drive 60 on the Highway, Not 75:
On the highway, stay close to the speed limit, and keep your speed as constant as traffic allows. Most cars reach optimal gas mileage at about 60 miles per hour. Speeding up increases wind resistance against the car, making the engine work harder and burn more gas. According to the EPA, each 5 mph over 60 that you drive decreases fuel efficiency by up to seven percent.
5. Turn Off the A/C:
Some air conditioners rob an engine up to five percent of its fuel economy. There is some controversy about this one -- many newer cars are able to compensate for the energy used by an air conditioner and don't suffer the same penalty for keeping cool.
6. Get Your Engine Tuned:
Most of us can boost our mpg by four percent with a simple tune-up.
7. Drive Calmly in the City
There's a red light up ahead. You're going to stop when you get to it. Do you keep your foot on the gas until it's time to brake for the light? Most of us do, but that doesn't necessarily make sense. The Environmental Protection Agency estimates that accelerating rapidly and braking hard can reduce your car's fuel efficiency by as much as five percent. And that may be a low estimate. Look at it this way -- are you willing to spend money to stop at that light sooner?
8. Lose Weight:
Government estimates say that an extra 100 pounds in your car can reduce fuel efficiency by up to two percent. And that's an average -- the smaller the car, the more extra weight makes the engine work harder.
So, empty the trunk. In winter, don't just scrape the windshield, scrape the entire car -- snow and ice add to the weight of your car.
9. Lose the Roof Rack
Wind resistance is the enemy of fuel efficiency. Do you have a roof rack? Every time you drive, it's making your car fight wind resistance, and burn fuel. Most of the time, that's money you're spending to carry an empty roof rack. Get a two percent boost by taking the thing off.
10. Change Your Oil on Time
After 3,000 miles, changing your oil (using the recommended grade) gives you back one percent of your car's mpg rating.
