SCR-Selective Catalytic Reduction system. SCR is sytem that injects DEF (DIesel Emission Fluid) into so called "mixer" or SCR cat, that eliminates NOx. DPF (DIesel particulate Filter) traps soot. Excessive SAPS (Sulfated Ash and Phosphorus) are polluting DPF. You need oils with Low-SAPS leves, which are ACEA C3 oils (usually those oils will have fallowing approvals: MB 229.5, MB229.52, BMW LL04, VW 505.01, VW 504.00/507.00, Porsche C3, GM Dexos2).

But, it is Full-SAPS oil and not suitable for DPF. This was discussed numerous times right here in this sub-forum. What FCA is doing is pure negligence.Pennzoil Platinum Euro in either 5W-40 or 0W-40...
Same add pack for both, also bottled as Shell Helix, Quaker State Euro, and a few others...
Pennzoil Platinum® Euro Full Synthetic Motor Oil
Pennzoil Platinum Euro Full Synthetic oil is designed for modern light duty diesel and high-performance engines in 0W-20, 0W-30, 0W-40, 5W-30 and 5W-40 viscosities.
Yes, BUT, due to known issue with bearings in that engine (and I am not sure that issue is addressed in this version of that engine) heavy oils are preferred. So C3, but as thick as possible.
Or simply does not care.
Schaeffer Synshield 9000 has the lowest sulfated Ash at 0.98
I checked out the oil Motul X-Clean oil you recommended. Seems to have almost identical specs of the Schaeffer Synshield supreme 9000 diesel oil. The Schaeffer is easier to get since the factory is in St Louis. What is you take on the Schaeffer for my 3.0 Eco diesel? ThanksOP, this is confusing subject that FCA made it even more confusing.
First gen. of that engine in FCA vehicles in the US had issue with bearings. Band aid was Rotella T6 of ACE AA3 oils. Problem in the longs run is of course, higher SAPS levels in T6 and especially ACEA A3 compared to C3 oils that initially were required.
Your engine should have bearing issue addressed and you should use C3 oils if you plan to keep vehicle pass warranty. Now, I said FCA should have addressed bearing issue. For that reason, I would personally go with thick ACEA C3 5W40 oil. I think best suitable oil for that application, taking DPF into consideration, would be Motul X-Clean Gen2 5W40 as HTHS is at 3.9.

I’m new at this and not sure what you mean. Would you explain it for me? Thanks
Approval process means oil company sends sample to vehicle manufacturer and vehicle manufacturer approves that oil for specific application.
Ok thanks. I will try the Motul. I plan on keeping this Jeep a long time. I was planning on hanging the oil every 5000 miles just for peace of mind. Thanks for tour help.
Yes...
