I need to figure out what I am doing wrong. My 2015 F350 4x4 has never seen over 17 mpg running empty on the interstate (cruise @ 70) and I typically get 9.5 - 10 mpg towing less than 9,500 lbs. @ 65 on the interstate and 12 mpg @ 55 on secondary roads. I currently have over 12,000 miles with about half of that towing my TT and have logged every drop of fuel put in it. My 95 7.3 F350 2WD EXT cab would get 22 empty and 20 towing an 8,000 lb cabin cruiser and the 97 7.3 4x4 CC I still have since new gets about 20/18.
I have no complaints about the power, ride or handling but for me the fuel mileage is just not there.
