It was probably only 91 anyway.

I have the 2.3L Ecobeast and it can run on 91, with a slight loss in performance and economy.
95 is the recommended and it develops the 233Kw on this tested by Ford.
98 puts the 2.3L in another league and going from 91 to 98, it makes 47 more horsepower at the rear wheels (in a Mustang), which is 35rwhp.
So I fill up on RON98.
