Fuel Mileage is like Golf Scores, some folks have a math problem. The new computers on the trucks measure it in different ways in different places and reset at different times, I found that out by READING THE MANUAL. If you set them correctly they ar pretty accurate. I get 11.2 to 12 with my F250 SD 4X4 6.7 towing my 3610 at 60 mph. I'm tickled to death. I'm retired and in no hurry thats why I drive in the right lane. I think the 3.73 axle overall gets the better mileage, mine is a 3.55.
