HI. I've been reading up on oil requirements and recommendations for these engines but have not seen anything specific to my needs so, if I missed it, I apologize but, here goes.
I have a '14 with about 160k miles and the CP4 pump went out. There was the recall on them and that part was taken care of under that recall, no issues there. The problem (if you can call this a problem) comes in when you consider that the dealership damaged the heads so badly during the fuel system work that Stellantis told them to just replace the whole engine (and new turbo too). So, on the plus side, I got a factory remanufactured 3.0 and brand new turbo out of this fiasco. That's a BIG plus but now, I have a question about what oils I should/could use.
I had been using Rotella T6, as previously recommended, and the original engine was perfect and running beautifully. Now, with the reman, would that remain the same or is the reman going to fall under newer factory recommendations? The dealer does not know.
Also, are those recommendations based on the DPF needs or engine longevity? I ask because, even though I just recently got my truck back (the dealership had it for 10.5 months working everything out), now, it popped up the "exhaust 90% full....." but then, the regen never happened and it QUICKLY went to 100% full and went into limp mode. Codes show the B1P1 EGT sensor went bad and didnt allow the regen. Dealership tells me that, if we can't force a regen after swapping the $300+ EGT sensor, then the DPF will need changed. Cost then? $4,000+ so, my next step, if the forced regen does not work, is a complete delete. Exhaust and EGR block/delete. So, how will THAT affect my oil requirement?
I have had great experience with Royal Purple in a couple other (gas) vehicles so I was looking at their Duralec 83540 5w40, which is CJ4/CK4 compliant for the DPF although it shows an additive package with zinc/ZDDP and does not specifically say that it is OK for use in the Eco. So, considering I will be doing the delete, but may not need to right away if the forced regen works, I guess I need to know oil specs both pre and post delete.
BTW, I will be installing the EGT and trying to force the stationary regen myself using the AlfaOBD and the MX+ interface to do it as I am not comfortable with my dealer garage's answers (or prices).
And beside the oil recommendations, can anyone also recommend a good quality delete kit? I was looking at Banks but, so far as I know, they don't offer one for the Ecodiesel.
Sorry for the short novel but wanted to get as much info as possible so no one had to ask. I'm sure I've still probably missed some anyway.
Thank you.
