are using a ScanGuage and do you think it helps you get better mileage? Ever since I got one, I immediately started to notice places in my commute where I could get better mileage and how just the least pressure on the gas pedal dropped my MPG. Major improvement over the ECO light. I now drive by the MPG guage more than by the speedometer and hope to develop more skill in milking the max mileage out of my VUE.
