dbackg Posted September 10, 2009 Report Share Posted September 10, 2009 Here in AZ, in the Phoenix metro area, it is near impossible to find 93 octane. 91 octane is pretty much the norm here and readily available everywhere. Regardless of what Supercharger we have on our SS, What OCTANE # are the Shelby shops programing our vehicle to run on? 91? 93? This would be a great item to address in the NEW upcoming SS Owners manual. Link to comment Share on other sites More sharing options...
