It’ll run off 87 but for best performance Ford recommends 91

I'll probably be running it on 87 most of the time. I don't need to eke out a few horsepower.

I have run, past year Citgo Premium. No issues, I'm getting 27.5 mpg combination.

What's not in the manual is the fact that if one has readily accessible 91 E-Free gas these engines absolutely love it.
