well my VX only gets 12 MPG and I accelerate normally and it sucks gas. If I accelerate slowly to the point of unsafeness then it doesn't suck gas as much...but if you accelerate normally then it doesn't help.

I'm talking if I acclerate to the point of slowness that I am the only car that can make it through the green light then it doesn't suck as much gas, but we should not have to drive like that to get the mileage that was stated to us from the manufacture.
