Ford's 6.2 L Engine Durability

This last summer I took our 2012 F250 (6.2) XTL 4 door short box with 3.73 on a 4,000+ mile trip. I had roughly 4500 miles on the truck were we departed. I was pulling a 255BH Conquest TT weighting in at 7000#’s. We left northern Wisconsin and made our first stop in Sundance WY. From Sundance we crossed the Big Horn Mountains (HWY16) and went to Cody, Yellowstone, Jackson WY, up to Glacier National Park, and then back home. Everyone who has traveled this route fully understands that I had some pretty impressive climbs on this trip. I drove the speed limit for a majority of the trip. Interstate speeds ranged from 65-70 and I drove 55-60 on most of HWY’s. I will say that I love driving this truck. I had all of the power that I could ask for. I prefer towing in manual so I could determine the shift points. I would like to add one more point. My father was traveling with me on this trip. He has the same truck as mine, but three months newer. He was pulling a fiver that weighs in at 9,000#’s. At almost every fuel stop, we put in the same amount of fuel (give or take ½ to 1 gallon). I do not understand how he was pulling 2,000 # more than me and was pulling a much taller trailer. Our driving styles are very similar and we were never more than a ½ apart on this trip. Anyhow, I took a picture of my information display when I pulled into my yard when I got home. I double checked my fuel receipts and compared them to the display cluster and was shocked at to how close the cluster was to my receipts . Only off by six gallons!

The results were:
MPG: 9.2
GAL: 432.9
Miles: 3998.3
