What fuel do you use and why?

I only use 93 in my stealth performance. I paid for 440 hp so I want to be able to use it.

I have a 93 tune now but even before the tune I used 93, I want the most power possible.

2017 Limited HD Tow.
93 towing or loaded up with people / cargo
87 around town, light load short trips.

Does it say in the manual that 91+ is needed for the SPP? I haven't looked.

93. Because the engine likes it and I spare no expense

93 when towing. It gives a big jump in mileage which means fewer stops and it’s not that much more cost-wise since I use less fuel.

I try my best to use a top tier rated fuel station. https://www.toptiergas.com/fuel-stations/ Premium is what I use since the truck seems to run and shift much better in my opinion.

Have been using Costco 93 octane on all my Ecoboost trucks for years. More power, better fuel mileage and they are Top Tier rated.
