This thread is why owner's manual's exist. Follow it and you'll be fine. It was created by the professional engineers at Ford who designed the engine.
No disrespect, but the “professional engineers” got more than the oil level wrong. i.e.- small intercooler, limited gauge selection, no manual release on the lift gate, single bolt differential, to name a few. Just my opinion, but I tend to lean more towards the folks who have picked the vehicle apart and tested its abilities than the monkeys who write the owners manual.
