Premium vs Regular Fuel

[zadagr]

Anybody know if the posted values for the 2.3L (and 2.7L) are based on using regular vs premium fuel? I noticed on the Bronco build, they list different numbers based on the fuel grade. I imagine there is some tuning differences between the bronco and ranger, but basically the same engines, no?

I had a 2018 F-150, I currently have a 2022 F-150, both 2.7 ecoboost, and I mix a bottle of jet fuel, "STP" octane boost with 87 octane gas with every fill up and the difference is very noticeable. I don't remember what it runs like without it, because once you put it in you don't want go without it. The Ranger Raptor I ordered is going to my wife and you better believe I'm the one that's going to be filling it up because I'll be taking it out every Saturday morning while she sleeps in.

Unless they changed this recently, All ford ecoboost stats are based on premium fuel. Most say they don't require premium fuel, but to maximize their potential you'll need to run 91 or higher octane. I always have and there is a difference.

Not sure on the Ranger, but the 2.3 in the Mustang is 30 hp difference if you run 87 vs 91. And you can DEF feel the difference when driving it. That is only 10% (Mustang is 310hp) but it sure feels like more. You can also watch the boost gauge and see that it will not push as much psi with lower octane; presumably due to knock.

Doesn't surprise me at all. These engines absolutely perform better with premium fuels.
