Changing the oil on 6.0

[JLDickmon]

I don't care what oil you use. Ford does not care as long as it meets the API rating for diesels (which Amsoil does not). Amsoil has their own style of "marketing" oil and I will not get into it with anyone. It is your truck so you decide what you want to do.

Amsoil does not have a CD/CE/CF rating?

I don't know of an amsoil oil that has ever been tested and approved by API, and I think thats what Dave's getting at.
