My father still has his 2001 F250 with a 7.3L that has over 350k on it. I have towed with it many times. The mpg computer is waaayyyy off compared to actual. It will generally say 18-20, but actual is 13-14 mpg which makes sense since Fuelly has it at 13.9 mpg combined average with 99 vehicles and 1.6 million miles tracked. My dad used to tell people that he got 18-20 mpg until I showed him his actual numbers.
I also used to have an F150 HD Ecoboost with a 6-speed. Fords algorithm they used to compute mpg must have gotten way better because it would say I was getting 16-17 mpg while I was actually getting 15-16 mpg. So going by the computers in both trucks, you would think my F150 Ecoboost was getting worst fuel economy, but in reality my Dad's 7.3L PSD was getting worst fuel mileage. It even gets worse fuel mileage than my Ram 2500 CTD(both stock and tuned), and my brother's old 2012 6.7L PSD even though the computer says it gets better mpg.
Towing the same trailer, the 7.3L gets about 1 mpg better than the Ecoboost but it it is kind of hard to calculate because it is very rare that we would tow the same trailer for a full tank so conditions were never the same. Towing performance was a lot better with the Ecoboost, but that is to be expected with over 100 more horsepower and two extra gears for better torque multiplication. Since it was an HD F150, it handled the load about the same if not a little better. I would hands down go with F150 Ecoboost if given the choice between the two especially since I was unloaded more than I was loaded and it got about two mpg better unloaded with a lot more power.
