Speaking of F150s, mine is a 2017 with the 2.7. If I'm staying around town its regular 87 octane. Ethanol free when I can find it, otherwise it gets treatment. On the highway , or towing , it's the highest grade I can find at the pump. Usually Exxon 93 octane because I take advantage of their discount gimmick's. That being said, around town, lightly loaded, see about 21 to 23 MPG. On the highway with 93, I can come close to 24 MPG. This came about because I saw a couple of lines in my owner's manual ( who the hell reads those) that said words to the effect that 87 is just fine overall, but for best performance, I don't recall this minute if towing was specifically mentioned, use a higher octane fuel. And as far as Pyder goes, I can't tell the difference what I put in it. Runs about the same, just a relatively thirsty high mileage 998.
