Anyone towing heavy, in the heat or mountains should be running premium anyway. If you don't the pcm will be pulling timing and taking away power that you need.
Yes the 6.2 gasser beats the ecoboost in towing fuel economy but it doesn't have the low end torque of the ecoboost and I have no interest in driving a truck that is constantly downshifting like NA trucks do. The ecoboost has the low end torque similar to a diesel but hp numbers more like a gasser. They are great at both acceleration and towing.
The ecodiesel is way low on hp and wouldn't be worth a darn for acceleration or passing
I pulled over 9k over the Rockies from Texas to Moab Utah twice and never used premium in my 2011 EB.
