<strong>Yahoo Message Number: 79932</strong>When I have rolling mileage set up for my monitor, the mileage never changes if I am on flat road or going down a 2 mile grade without touching the fuel pedal. Am I still using as much fuel going on a flat road as going down hill ? Whatever the answer is why ?<br/><br/>Stan<br/><br/>2005 Inspire <br/>51406
