Thanks for the link. The transition should be fairly transparent from a consumer perspective. SHELL LUBRICANTS ANNOUNCES SHELL ROTELLA PORTFOLIO TO MEET API CK-4 AND FA-4 CATEGORIES

These specs are backwards compatible. Ergo, anyone's existing stock of Rotella T6 would continue to meet the FCA-published requirement, and those who wait to buy their T6 until later will simply get a version of T6 that's tweaked to meet CK-4 standards (i.e. that also meets the CJ-4 standard referenced by the manual).

It's so nice to be able to go to a random store and find oil for my vehicle is in stock. This switch to the Rotella T6 spec has been great.

I get the sense that the new CK is an attempt to standardize so every modern diesel won't need a specific oil that meets each engine manufacture's specific material standard. It should not surprise anyone if the FCA MS were to change yet again. The most recent one was to accommodate an oil that could immediately address a particular set of issues, and induced somewhat of a compromise between best for emission system protection and engine longevity. The next MS will provide for both.

I have a 2014 and have been running Rotella for about 1,200 miles now. I have experienced no difference.

Thanks for the input. Do you happen to know what the "set of issues" are that made FCA change to the Rotella. When I called them the folks on the phone at customer care say, they been instructed by marketing not to say anything about it. Weird. What are they hiding. I know the RAM site for ecodiesels have reported quite a few engine failures.

Keep in mind that there are many more success-stories than failures. Driven hard but treated right, and not "put up wet", these things serve their owners well. Unfortunately, the rate of failure is still uncomfortably high.

I cannot elaborate on anything, specifically, but there is enough information out there that you can piece it together pretty well. The most telling bit was the RTT directing among other things, that all built unsold 2016 EDs have the engine oil replaced with the T6. Given what this oil buys from a lubrication performance perspective, it's not hard to narrow in on potential areas of concern.

To think FCA is hiding things may be a bit of paranoia. I suspect the marketing side simply doesn't know what it's all about and understandably doesn't want the direct line with customers giving out bad information.

This isn't over. How they plan to handle previous MY vehicles still in warranty remains a mystery. The unannounced updated owners manual supplement leads me to believe that some kind of satisfaction program is in the works.

I really hope things get worked out. With FORD nipping away at their heals, It would be a shame for them to walk away from the VM diesel offerings. Particularly now, since reading that the 3.0L is also planned for the next gen Wrangler. Jeep engineers are true enthusiasts and would probably rather die than not see a diesel Wrangler built. (especially a diesel Wrangler pickup)

Re: Rotella T-6 in our diesel?

I just did my 3rd oil change at 26k, used Rotella t6 and an afe oil filter this time. Let the engine run for about 10 mins and drained all the nightmarish black Euro L out. Also changed out the fuel filters using oem replacements. No issues so far, just glad they stopped recommending the expensive oil

Diesel GC: Here is something I'm not used to in my gas engines. In regards to your "nighmarish black oil" Check it now that you added the new oil. It will still be black. I just got mine changed to the Rotella by the dealer, drove it 5 miles home and it already is gray/black. Why is that. Is it the diesel or is it the emissions equipment not letting the soot out (anyone know). Is the internals that filthy that the oil immediately turns black?

Yep its always been black, just comical compared to a conventional gas engine. From what I've heard the black is mainly caused by soot blow by thru the piston rings. Someone who has more insight might chime in but I really dont know if the emissions equipment is making it more black than normal

Primarily the EGR system is responsible for the soot in the oil. People with tunes that turn off EGR universally report clean looking oil changes after the tune has been in for a full oil change cycle.

Historically, this has been the cause since before EGR was a gleam in the EPA's eyes. Now days, as akinney followed with, it's the EGR that makes the discoloration almost instantaneous.

This is true. My oil looks new 2,000 miles post GDE tune.
