Read your owner's manual.
Follow it's instructions.
Purchase oil that meets manufacturer recommendation.
Wash, rinse, repeat.
Here's a link to the API sponsored
Motoroilmatters.org website that has additional information.
I agree, though there is some ambiguity. For instance my newest truck says "FCA Material Standard MS-10902 and the API CJ-4 engine oil category is required. Products meeting Cummins CES 20081 may also be used." and along comes Triax (and most others, not picking on one particular oil) listing Cummins CES 20086 under "Product Specifications"...
There is a reference in the manual that does recommend only using API-certed oils... so I guess that's the short answer- if it doesn't have the API seal then it is unacceptable to use. That does run counter to the entire Amsoil culture.
Thanks for the feedback guys.

Cummins (and most commercial engine OEMs) publish approved lube list. These show each product in the market that they have approved for a given engine model. The lists are usually comprehensive and updated regularly. Now I do not know if Cummins publishes this for the FCA B series engines, but it's worth a look. Bottom line is to not use an oil that is not on the list (in my view).
This is where dealer can access the Cummins registered fluids list:
