Any advantage to using premium fuel

[Foogie]

There's a MotorTrend article from 2022 or 2023 that I wanted to paraphrase regarding the SO Hurricane. Bottom line: It stated that the advertised power numbers were generated on 89 Octane (Mid-grade) fuel. Their (RAM) website recommends 87 for SO while the owners manual page is above a few posts. I'm running 87 and will continue to do so I think until I tow my boat in the spring then I will switch to 93 octane. I might mess around with 89 octane just to see if I notice any difference in performance or mileage.

Ford's EcoBoost 3.5L runs on regular and that owner's manual basically says the same as our manual regarding 91 octane. Mine runs great on 87. I had a buddy years ago who ran his Audi A4 on regular despite it "requiring" premium. No issues.
