No fuel filter or oil filter part numbers.The Wrangler diesel supplement manual has been posted on the Jeep - Owners web site.
it seems that Chrysler's way of Adopting this "Standard" is through an approval process, other Standards may work and be better, but I'm not wanting to get involved in all that. This is a short list of Chrysler MS-12991 (Rotella T6 5w-40 is not approved for MS-12991 as of today 1/11/2020)Thanks for posting that link. I see they recommend the engine oil meet MS-12991. I had hoped the same oil spec would apply from the gen2 Eco and Cummins, which Rotella T6 5W-40 was one of the approved. I don’t see that spec mentioned on the Rotella site however.
Do any of you have more info on this?
