2003 GMC Duramax UOA, Thoughts?

[milehighassassin]

My father has a 2003 GMC Duramax. He recently switched to Amsoil.

He is running Amsoil AME (15w40)
He ran it with a NAPA Gold Oil Filter.

His plan was to run 15k miles on it before changing it. He ended up going 17k and we did a UOA on it.

On this change we kept that same oil in there but switched to an Amsoil EoA Oil filter (EOA052)

I think on the next change we will go with the same Amsoil filter but go with Amsoil DEO 5w40

I think the numbers look pretty good. He does tow a 5th wheel.

I think he changed his air filter. If not I will have him do it.

Thoughts?

My bad.... I just realized there was a forum for these types of post's. Would a mod, move this?

Thanks

The numbers look really good. Excellent really. But please NO unassociated links to Amsoil.

Seems like the copper number is right on par with other Duramax trucks huh?
