Thats what I used to get for mileage. I had a 2019 F250 Ford with the 6.7 turbo diesel and got about 5000 miles to a tank full. That's about 1000 miles to a gallon of DEF. Now I have a 2020 F-350 with the same motor but get about 1000 to a tank. That like 200 miles to a gallon. The dealer just says that if I tow an RV or anything of weight that's what you get. Now my new RV is a little heavier but that much of a difference?
Is anyone getting that kind of mileage when towing using DEF. I also understand DEF is DEF and paying twice as much for Blue DEF just does not seem justified.
