07SGT Posted August 6, 2013 Report Share Posted August 6, 2013 Just curious. I was looking at the Ford site last night and "building" a Shelby GT 500 with options and checking the price. I noticed Ford stated the Shelby GT 500 requires 93 octane. What do you guys in the west do since the highest available is usually 91 octane.
