When giving the milage you are getting are you giving the number on the dash or at the pump? I have found that in all my tanks I have had it only match the figure I get at the pump ONE time. I average between 2 to 10% lower at the pump. So for the people that use the dash figure you might want to start figuring at the pump and see if there is a difference for you. Kevin
