Car and Driver tested the 2022 Expedition with regular and premium fuel, and performance was notably increased with the premium fuel (mileage was only slightly increased). They tested an Expedition model with the standard engine, without the Stealth Performance Package, so my guess is that the SPP would likely see an even greater performance increase by using the 93+ fuel over regular.
Besides that, after dropping $86k on an upgraded, performance model, giant sized SUV, specifically so it would still get up and GO like a mid-sized sports car, the last thing I’m concerned about is dropping in an extra $30/month for Premium fuel. I run 93 octane mostly, but IF I could find 93 ethanol-free near me, I’d run that instead.

We tested higher octane fuel than manufacturers require on the Honda CR-V, BMW M5, Ford F-150, and Dodge Charger to see if it impacted acceleration or MPG.
