Ford minimum requirement for Ecoboost engines is 87. It was for my 2015 and has remained the same over the years. That said there is a noticeable difference between regular and premium as there is with most boosted engines."Ford recommends using the highest octane rating available, but you should not use less than the 90-octane gas in Ford EcoBoost engines." Premium gas is not required to protect the engine." Most of the EcoBoost drivers (I've seen at the pump) use the cheapest gas possible (87 octane). Most gas stations (where I live) have two choices (87 or 91) of octane.
Just a silly comment. There are many members on here driving GT350's, GT500's and Mach 1's as their daily driver. It's a Mustang not a Bugatti.If you buying a DH, you are not to be using it as a daily driver, so you be will probably be buying gas about once a month.
