My manual says absolutely do not use E85 fuel. It also says don't use less than 87 octane, even in the mountain states that offer regular in 85 octane.
It recommends use 87 octane when not towing or hauling.
It also suggest performance may be improved if premium is used when towing and/or hauling.
I have a 2014 F150 Eco-boost 3.5L engine.
Your turbo can vary boost to to keep the air charge in the cylinders optimal even at altitude thus you will still need the same octane at altitude. Normal engine gets less dense air thus lower absolute pressure and less likely to try to knock/detonate
