"Remote Chance", yes. I guess its about 1 in 1,000 odds. I'd play that. First of all, these engines rarely have engine lubrication problems that need warranty attention. Second, many times Ford will likely just see if the oil looks clean with no signs of sludge or deposits, which Amsoil will deliver ! People have written in to these forums about this with direct experience working at dealerships, and around half the time they just do an engine inspection to look for signs of oil-neglect.

Potentially they could demand oil change receipts to show the owner used an API oil of the right spec & weight, something they don't always do though. A sample to Blackstone would result in a match between almost all known brands, potentially again, since this probably wouldn't even happen...

That is the real key here. I say go ahead and play the 1 in 1,000 odds there would ever be an issue. The odds might be even better than that, I'm not sure. Conservative odds.

Their oil filters do not filter as well as the Fram Ultra oil filter. Ultra is cheaper too, good for up to 20,000 miles due to its synthetic wire-backed media an silicon ADBV.
I'd choose a patial-PAO name-brand oil like Mobil1 Annual Protection or EP or Castrol Edge gold-jug if you want a better oil than Motorcraft. .... Amsoil SS is very good, yet the others have caught up over the years.
Another premium oil choice for ecoboosts would be Rotella T6 Multi-Vehicle 5w30, extra HTHS to battle fuel dilution that plagues your engine, or there is also Mobil Delvac 1 Advanced Fuel Economy 5w30 (HTHS 3.2), both oils carry the API SN gasoline engine ratings, along with a lot of tough diesel engine specs too.
