Well, all I can say is my son, who is among top execs at Ford, posed this question to one of his engineer counterparts and was told ALL '13s and '14s were equipped with the additive in production. Sorry, but I'm more comfortable with my source than I am a dealership techie. No offense, of course.
If this is true(and I am not doubting they have the additive) then I wonder why some of the 13 & 14's still experience the same problems the 11 & 12's have.
