FCA has officially changed the oil specification on Ecodiesel / VM Motori A630T 3.0 diesel engines from C3/MS11106 to API CJ-4 "Synthetic" 5W40.
The change was made to the diesel supplement in the owners manual for all years. Can find yours here.

I of course have been using CJ-4 all along, and while I didn't foresee this change. I did have a negative opinion in the use of C3 oil for Diesel engines.
