Want to save the equivalent of 30 cents a gallon on gas? The Detroit News says anyone can realize those savings if they just drive five miles per hour slower than usual. In fact, Department of Energy researcher David Greene estimates you could save $12 by driving 10 mph slower on a 500-mile trip. The tradeoff: it would add one hour to the trip (that you'll never get back). Don't get too overly zealous with your penny-pinching, though. The AAA warns that driving slower than 55 when the rest of the traffic is zooming past at 70 - 75 is "a recipe for a potential crash." Drivers in some states won't have to worry about that, though– Alabama, Michigan, Minnesota and Vermont are in various stages of considering bills to lower the speed limits on highways, in some cases to 55 mph. We're monitoring sales of CB radios…

I gave the old "go the speed limit" a try in my truck (4 banger ford ranger). The result? About 5 mpg higher

Speed limit for me when I'm on four wheels

Yeah, the gas I save in the car I use in the bike.

Last time I tried driving the speed limit I wanted to get a glock and blow my brains out.

Tried dropping from 75 to 70 in my MR2 a few months ago. Got the same exact mileage. Just bought a turbo Miata for my daily driver. Ill try it again with that and see what happens.
