Mileage
I just replaced my 2001 7.3 powerstroke with a new 2016 6.7 powerstroke 4X4 I know the 6.7 won't get the mileage that my old truck got but once it's broke in what kind of mileage are you 6.7 owners ...

Even the hand calculated one is not perfect either, how full did I fill it? I find over the years there isn't enough difference the hand calculated one and my over head computer. Mileage is going to very from fill up to fill up because of all the veryables. So what if there is a .3 or .2 difference. I have a 50 gallon aux tank and 38 gallon OEM tank that gives me an advertised total of 88, but you can get more fuel in than what it says how much I have no idea but only a guess. I can put 4 more gal in the OEM tank after the nozzle clicks off at least 10 gal in the aux tank. A .3 or .2 error isn't going to mean squat to me when the fuel gauge get near 1/4 I start looking. By experience I know I can go 200 or so more miles. I get between 8 and 11 mpg. The wind is the biggest factor. When I figure my fuel stops I fig it at 10 mpg works well for me for the last 15 yrs
