All the drama about MS-11106 seems to be over with FCA changing their oil recommendation recently. All the new owners manual diesel supplements now say:
We recommend you use 5W-40 synthetic engine oil such as MOPAR or Shell Rotella that meets FCA Material Standard MS-10902 and the API CJ-4 or ACEA E9/E7 or ACEA A3/B4 engine oil category is required.
This now aligns with the recommendations for the Cummins engines. CJ-4 is an API specification for low-ash formulation motor oils and can include 10w and 15w oils in both synthetic and non-synthetic formulations. Importantly though only synthetic 5w40 is approved for our engines.
ACEA is the European equivalent of API and their A3/B4 specification is also a low-ash formulation.
