Glad everything's finally running well for you, i'm a recent fan of some of Amsoils gear oils etc. but that motor oil you're using, it's very good, but it's expensive and still on the slightly thinner side of 5w30. If you fancy a change, give Quaker State full synthetic 5w30 a go, should wear a little better than the Amsoil and should be a lot cheaper.
I will say that the rear diff oil you have in there is an outlyer in their range and has quite poor wear ratings - the previous diffs in the F150 call for 75w140 and i don't see a reason not to go back to that in the 13th gen, i think even Fordtechmakuloco recomends the same. The good news is that Amsoil's 75w140 tests extremely well by comparison, i'll be ordering some of that very soon along with the ATF. Curious how your testing of the ATF comes out for you.
