negative. I am always concious of my mileage and my driving habbits. I am annal about it. You won't find a V8 Explorer getting 20 mpg driving like I am doing....it's just not gonna happen.....but it is safe to be skeptical
I seldom ever stop for red lights, as they generally have turned green by the time I get there.
Do this and you'll save a bunch of bucks on gas, not to mention your brakes will last 3 times longer, and you will double the life of your drivetrain.
