Slowing Down To Save Gas

Are you willing to spend more time behind the wheel? It could end up saving you gas.
According to the New York Times, Virginia Senator John Warner is suggesting Congress lower the national speed limit.
Warner says it's one way to cut costs at the pump, while one mechanic we spoke with says it's true.
Mark Hendry with Southern Automotive says driving between 45 and 65 miles per hour stretches your gas mileage."Once you exceed that you're actually using more throttle to make the vehicle go at a faster speed. the only down side of that is the person that is trying to run 75 behind you is going to try run over you, you'll have to stay in the right lane,"Said Hendry.
But not everyone is ready to slow down."I mean on the interstate on the freeway I don't see that 70 is too fast, Said Brandon Branch while driving to Pensacola. "I don't think that's going to help, I really don't. Back in the 70's when they had it at 55, I don't see where it saved that much on gas,"Said Ronny Deville, another driver. If going slower than 65 miles per hour is unrealistic, Hendry says you could also save gas by keeping your vehicle in tune and always checking your tire pressure.
