H/O Recommends premium for full power, but is there any advantage in the S/O? I have heard and seen conflicting reports. Maybe premium fuel while towing a decent size load? Thoughts on this and what if any advantage premium fuel might give.

Purely anecdotal evidence here but I gave it a try in my S/O a few times when I was towing and/or it was hot outside (per the recommendation from the owners manual) and I seemed to get worse milage but I might have noticed some more power. Hard to say for sure, it might have been in my head as well. I don't see the need to spend the extra money on premium fuel. In my area we typically see 87 as regular, 91 as premium, not too common to see 93.
I think we switched over to winter blend fuel in my area recently because I noticed a 1-2 MPG decrease per the trip average MPG in the cluster but I would see similar results in the Hemi when it was winter blend.

It does give it more timing when running premium.
