Interesting. I wonder what, if any, effect this will have on a warranty extension for the engine. IF they change the recommended oil spec, will they be obligated in any way to offer an extension?

 

I'm thinking that this is an interesting way out of warranty issues for FCA. They would now recommend a new standard that was not available when their first recommendations came out. No obligations since the new oil classification was not available at that time.

 

This would mean that even the Rotella T6 some guys are running won't necessarily be compatible, but based on Rotella's website it sounds like they will 100% have a version of T6 that is CK-4 compliant, and there may be a version specifically for our truck meeting FA-4

I don't think PC-11 has anything to do with our trucks. As I read this some time ago it focuses on big rigs and has been planned for sometime. That doesn't mean a change isn't coming but do not think it is tied to this new oil category and specification.

This isn't a specific oil, it's an oil standard developed with new motors in mind.

From Rotella's website:

Diesel Pickup Trucks: What CK-4/FA-4 means for diesel pickups.
Peace of mind. The confidence that you’re using diesel engine oil that has passed strict tests for engine protection and performance, especially when you’re hauling heavy loads. Protection you’ll appreciate now and in the years to come.

 

Interesting.... I can't wait to see how this all plays out.

 

I may have missed it in my quick look over, but what I read seemed to be in reference to more commercial vehicles and heavy duty diesels which were never effected by MS 11106 in the first place. Does it say in there somewhere that Ram is going to make changes?

 

I'm no oil wiz, but has Ram release a statement about any of this? From what I see this is a revision of the old CJ4 spec which doesn't pertain to our trucks. I don't see anything that says it will effect the MS11106 spec required by ram.

 

The new spec will be more on engine lubrication...it will be coupled with tuning updates to offset the effects on the DPF/SCR/EGR.

I 2nd Layhne, FCA just slower then most ( Builders) when it comes to Making changes... At times I figure its just another bean counter blowing his horn. MS11106 is not wrong/bad oil its just not the package I would run in in anything I own that includes My weed wacker, when better lubes are available.

 

We would not steer folks in the wrong direction. FCA has been testing the Shell Rotella T6 5W-40 for a few months now. All the trucks currently being built are stuck in containment at the assembly plant until an oil change is performed to the 5W-40. The oil has already been changed in Italy at the assembly plant. We would expect dealer notification within the next month or sooner. FCA gave us the go ahead to tell all our customers to switch to the 5W-40 Shell Rotella oil at the next oil change.

 

Wow... good to know.

 

Hey GDE, that is very interesting! Thank you for sharing! I ordered a truck a few months ago and imagine it must likely be sitting in limbo for this reason.... Does this mean that they will go back on trucks that are still at the factory, but had the original oil and put T6 in instead? If that were the case they must be highly motivated to make the change rather than let those ones run one change worth of the original oil and just change it at the first interval.

Any truck built cannot be shipped from the plant to the dealer until the oil has been changed. Dealer documentation will be coming forthwith. The spec'd oil will be same as what stocked for the Cummins at the dealers (Rotella T6 5w40 with rating SAE CJ-4), but any quality synthetic diesel oil meeting that SAE spec will work fine as well.

 

Thats big news. Its about time. T6 will serve people well. I'm already stocking up on T6 for my CTD.

 

Which sends me back to my original post. Looks like it will be an addendum to the original spec. Basically saying "either/or". If they send a cease and desist/replace the old spec, that may lead to trouble.

So, I ask one thing.............I wonder if this change in spec at the assembly plant in Italy as well, has anything to do with the lower end engine failures? Because, as has been proven through many oil analysis, the factory assembly line full is unknown and not the same as any recommended oil available to us. I'm certainly curious, as my source didn't supply this same info as GDE just did. The exact language of the new supplement is tantamount in these cases.

 

I feel FCA would like nothing better than to have a reason to void your customers warranty. Or are you saying FCA is going to endorse your tune also . I'm running your tune but excuse me this sounds fishy.if we switch before getting true FCA notification were toast and could definitely loose our warranty

 

Fishy? And this advantages GDE how? How are they profiting from this. Just wait until the FCA official announcement. No big deal

The Euro L has worked well for me for 145,000 with great lab results even with extended 15,000 mile intervals. That said I switched to the T6 because of convenience ie I could buy it local, and cost, and last confidence in it being a good product for our truck including the emissions system. Post warranty I don't care about the emission side as if I had a problem I would delete & upgrade my GDE tune but I mentioned it because most are still under warranty and should do what it necessary to protect it.

Thank you GDE for answering questions about oils T6 & emissions on that a long time ago. Oh and I have had good extended oil analysis results on the T6 as well. Also thanks to whomever gave the heads up on O Reiley's special with rebate as it brought the price down to $3.75 a quart. Hence you see 12 gallons in my garage.

You are welcome. I just found it cheaper at walmart.com 3 gallon pack with free shipping to house.

Shell Rotella Synthetic 5W-40 Motor Oil, 1 Gallon (Casepack of 3 units) - Walmart.com

Same rebate on shell.

Save $5 per gallon rebate | Shell


ENJOY. I just ordered 3 gallon for me.

 

Interesting....I guess they are tired of replacing engines.

 

Aside fro the "bombshell" GDE added, I bet the new oils PC11 oils are more costly that the older ones. So, I wonder if the change interval recommendations will also change?

Now I need to go get some T6.

 

Thanks GDE! I really appreciate all of your insight!

It works when you scroll to bottom and select other.

 

Yeah u130747 after rebate that equals $3.33 a quart! Man no wonder I couldn't remember your screen name. You need something in your signature or something that says the whole world just calls me Hank. Or something lol.

 

That was my employee number at United Airlines. My real name is Bert.

 

I currently have T6 in my Amazon "subscribe & save" list where I get the 3gal pack delivered every 4 months @ $48.86ea.

 

That's a pretty outstanding price. Is that Amazon Prime?? Best I could just find in a quick search is $57 a 3 gal pack.

 

The choice of changing oil specs could be for multiple reasons. Using the same oil as the Cummins simplifies logistics within FCA a bit. A 40 weight oil helps hydrodynamic effects in certain operating conditions. The ED seems to regenerate quite often in stock form and oil dilution could be a potential issue depending on drive cycle. Certain US/Canada fuels might have a different effect vs. Euro fuel on the engine oil properties. I think the Shell oil has a higher TBN vs. factory if the memory is not failing and might be able to handle fuel dilution better. Oil change intervals might need to change based on driving habits vs. the typical 10,000 miles. Blackstone tells us we can run 15,000 miles OCI, but we still change it every 10,000 miles.

 

Interesting. A few thoughts/comments. Ref fuel dilution I don't think any oil tests that have been posted here show any significant fuel dilution. I agree the T6 has a higher TBN but don't think this has much to do with handling fuel dilution. I suspect the 40 weight will handle fuel dilution better than a 30 weight oil. AS I understand it (which I do not guarantee is correct) it is the product of combustion of the sulfur in the fuel that is the primary contributor to using up the TBN in the oil not just the raw sulfur inthe fuel. I don't recall any of the oil tests posted here having a TBN below 1. Some have had comments that it is getting low but not an urgent issue.

The above is not to say that the oil tests posted on this forum cover all types of operating conditions. I do believe one person with an engine failure had been doing oil testing at least once with no bad test results a few thousand miles before the failure. My own tests have had comments about the oxidation level being high but after discussion with the techs at the firm doing my analysis I am not sure this was a valid analysis for our oil and my viscosity had only changed slightly.

All the best and it will be very interesting to see how this all plays out.

Thanks again for your strong technical input to this forum. It is well appreciated.

 

Thanks for feedback GDE!!

I ran T6 Rotella 5W40 in my Cummins year round without any motor issues, granted it's a different animal, and would really like nothing more than to be able to use it again because I have 6 gallons still sitting in my garage !

 

Howie12,

Where about in North WI, I have a place between Ashland and Superior.

 

And here I am sitting on 11L of Mobil 1 ESP waiting for my next oil change in 1800mi lol. Guess I'll use it up and go T6 next time.

 

So I am due for an oil change shortly like next week. Change over or wait on Chrysler?

 

I feel vindicated for making the switch to T6 in April after only 5,000 kms.

The drama on the oil spec was not from FCA. It was from members of this Board. It would be an amusing read to go back and read through the 2+ years of posts concerning oil. I think I read most of them before I made my decision.
