Not too many miles yet, but 87 octane for first two tanks

Ford said their performance numbers (HP ratings, etc) based on 91 octane or better…so that’s what I will be using.

I run 93 exclusively. I just feel high performance engines and especially turbo/super charged cars need 93. It has worked for me so for.

I picked mine up in Indy and drove it to Austin burning 93 because I hadn’t realized it was designed to run on 87. Been running 87 since and see no performance issues. Everything I’ve read says you’re throwing your money away burning 93.
