True or False, These Tips Save Gas?
We've all heard the tips on how to save gas. And, as fuel prices continue to climb, we're hearing them almost daily on TV and radio: Don't drive aggressively. Drive at lower speeds. Use cruise control. Don't use air conditioning. Keep your tires properly inflated. Avoid excessive idling.
So, which ones are true? Edmunds.com, a popular online Web site that has all sorts of car-buying and maintenance advice, put the tips to a test (many tests actually) to see if they can really, truly help you save gasoline.
Some results may surprise you. For instance, tire pressure had no measurable effect on gas mileage in Edmunds' tests. Similarly, there was no measurable difference in using air conditioning or driving with it off with the windows open. "So just do what's comfortable," Edmunds says. (Meanwhile Heather L. Cooper, an assistant professor of mechanical engineering in Purdue's College of Technology said if you use A/C, do it on the recirculation setting to minimize the energy required to maintain a constant temperature.)
But some of the other tips do indeed help you trim your fuel bill. For example, Edmunds found that by easing up on the gas pedal when accelerating, you can save an average 31 percent on gas. So, instead of going from 0-to-60 in 10 seconds, try doing it in 15 seconds. "You'll feel the savings immediately."
Similarly, on long trips, slowing down to the speed limit can result in an average fuel savings of 12 percent. Of course, Edmunds notes, driving the speed limit does have its drawback: "Impatient drivers behind you." In their test, "one driver became so irate that he tried to run our editor off the road."
