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.

Do what you like but you are leaving power on the table. Then throw in the small CAC on the ecoboost and you are losing even more power due to excessive IAT2 temps. Put an aftermarket CAC on it and it will quit retarding timing as IAT2 rises

I was easily able to do the speed limit the whole up the mountain passes. So there were no issues with power nor did i need any more. I ran regular to save costs on the trip. If I would have needed more power then I would have ran premium, but it was not need on either trip.

I hear what you're saying about constant downshifting. I hate that. But it's non-existent with the 6.2 / 8 speed. Constant downshifting and high RPMs was the main reason I got rid of my 6.0 HD. I won't get another one until they change the powertrain.

Did ram fix the emissions on the eco diesel after they got caught cheating? Or was this a 2016 model?

My 15 6.2 will ping like crazy with 87. I run a mix of premium (93) and 87 to reach 90-91 octane and straight 93 while towing.

Guess that's why premium is "highly recommended" for the 6.2L but only just "recommended" for the Ecoboost.

I ran premium for a few thousand miles when towing my ~8K trailer with a 2011 F150 Ecoboost. I saved some in fuel economy but otherwise didn't really notice any difference. Never any pinging. Maybe in the heat and when towing something heavier ...

"what I am not wanting to post"? Really? Seems to me I am the one that posted the link to the owners manual.

The link, which CLEARLY states that "for best overall vehicle and engine performance, premium fuel with an octane rating of 91 or higher is recommended".

You can add your own adjective of "power" if you want. Ford did not put it in there. You did. Maybe they wanted to say for the best engine longevity, use premium. Maybe they wanted to say "for the smoothest performance, use premium".

The owners manual states they recommend Premium. They don't say why. I take it at face value.

The sky is blue. Let's argue about that.

Really? I though you were done?

I don't know how you can miss the big 87 OCTANE and the words "designed for 87" in the owners manual link that you posted. Here let me show you a the image just incase you cannot click on your own link.



It clearly states that the EB is designed to run on 87 -BUT- for over all performance (which is in the form of MORE POWER) then they recommend 91. PUTC even backed it up by posted how much power is gained by running premium. I don't know where you are getting that they recommend only or at all times especially when they just state that you can if you want more power. You don't need to run the truck on premium because it was designed to run on 87(like it clearly states) unlike the 6.2 which was designed to run on premium. If you want more performance, then you can run premium.

I know you have this undying hate for me, but that is no reason to brush of the facts.

Unless I missed it seems a key ingredient is missing, the rear end gear ratio. If you make comparisons make them apples to apples not a marketing ploy by a manufacture which they are all guilty of.
