What size tires are you running ? I went up to a 245/75 and the odometer readout is about 20 miles different from the gps with a full tank( if I remember right ) . That is definitely enough to skew your mileage if you're using the dash display. If I want to check the mileage, which I never really do, I use my GPS.
