hi, i'm looking to increase my gas mileage on my 2003 yukon...i'm soon to be lifted 6-8 inches on 315/70R17 and any extra gas mileage would be greatly appreciated. I've been told by my local shop to get the edge, wondering if any of you knew about their product? also i keep seeing stuff about blackbear? whats that, how do i use it, and how much does it cost?
