I recommend visiting fueleconomy.gov for some very helpful tips on how to save gas that go beyond the obvious making sure your tires are properly inflated. To save you time and sum up the site the rules are pretty simple:
- Drive sensibly: Our government reminds you that "Aggressive driving - speeding, rapid acceleration and braking wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town." I believe it. I love when I see a Prius speeding and weaving down the highway. That is the truest form of hypocrisy I can think of.
- Remove excess weight: This is one I am always guilty of. The back of my car currently contains a jogging stroller, a 22 pound SCUBA weight belt I've been too lazy to take out, a beach chair, various beach toys and a 1 gallon jug of windshield washer fluid. I estimate that's about 40 pounds of unnecessary weight.
- Don't idle: There are actually laws about this which you can check by state here. In Massachusetts you can't idle for more than 5 minutes or you will be fined not less than $100.
- Don't speed: This graph says it all. As tempting as it is to fly down the interstate at 80 miles an hour it is actually extremely inefficient. Highest fuel economy is around 55 and drops fast after 65 miles an hour.
