The Gen 2 ('15-17) and Gen 1 (11-14) motors are very different, as are the Gen 3's again. Ford spec'd the oil appropriately for each of those engines. And I'm talking stock, unmodified engines. Once you start dinking around with the motor you're on your own anyway so run whatever you like, Ford won't care since they won't warranty it anymore. I just love oil threads, so many smart guys out there who know way more than Ford and their 10,000 engineers.
