Re: Hand Calculated Mileage figures, post them here!

I am averaging high 14- low 15 mpg with 3.55 gears. mixed city and highway miles unloaded. Every fill up, the lie-o-meter is off by 1 gallon of usage and 1 mpg. I fill my truck up the same every fill-up. How can the computer lose 1 gallon of fuel and not account for it? My lift goes on this week with 37's and I predict that my lifted 6.0 with the same size tires will out shine in mpg. Not too happy with the 6.7's mpg but everything else is all smiles.

2011 F250 Golden Bronze Fully Loaded King Ranch FX4 with Navigation, 6.7 PSD, 4x4 E-locker, Color Matched Line-x Bed and toolbox, Icon Vehicle Dynamics/One Up Offroad Suspension Lift, BMF Novakaine 8 Chrome 20x10, Toyo M/T 37x13.50x20, Color matched Brake Calipers, Amp Research Steps, H+S, CAT/DPF delete, AFE and 1000 watts of JL Audio and Focal
