As did I, Floridaman. Odd that you felt the compulsion to abdicate the technical discussion in favor of wide-ranging, tangential ad hominems.

Regardless, I imagine we can both agree this particular discussion was off-topic for the thread.

Re: Rotella T-6 in our diesel?

Well today I got an oil change from the dealer and we had a bit of a disagreement on the engine oil specification for my vehicle. The dealership said it should be Pennzoil 5W-30. I agreed that it used to be Pennzoil 5W-30, but said there was a TSB for the 2016's that changed it to Shell Rotella 5W-40. In addition, Jeep released a new diesel supplement manual for the 2014's (8th edition) last month that specifically says 5W-40.

He showed me a tech instruction print out did say 5W-40 in the description, but he said that was a typo and showed me that the part number for the oil on the same page was for the old 5W-30. I agreed that the part number he had was for 5W-30 but explained that I didn't understand why Chrysler would put out two pieces of information changing the spec but not change the part number on the work order.

I paid the bill and left the dealership with 5W-30 in the engine, however I'm convinced that this isn't the right oil. I am seriously concerned about the dealer network's ability to keep these vehicles repaired in good condition as well as the long term health of the vehicles themselves. I still believe the cylinder head replacement I had to do in August 2015 was directly because a different wrong oil was used twice previously.

They also forgot to do the State Safety Inspection even though I put it on the work order when I made the reservation online. I had to take it to a service center around the corner to get that done as they were unable to do it before they closed for the day.

It is ridiculous to me that dealerships can't be trusted to put the right oil in the vehicle and follow work orders. I pay extra for dealer service to avoid these kinds of issues somewhere like Jiffy Lube. I don't feel like I should be getting into a fight with the service manager about the correct oil type. Is that too much to ask from the Chrysler dealer network?

So I emailed my contact over at Chrysler corporate to verify that the wrong oil was used and to figure out next steps. But needless to say, I am pissed and once again disappointed at how much effort I have to put into telling the dealership how to maintain their own vehicles.

I disagree. We had the '14 cylinder head replacement as well, and it's my opinion the TSB was due to carbon build up on the valves due to the EGR. The TSB applies to all 2014's and is indifferent to what oil is used. Apparently the redesigned heads aren't as susceptible to the carbon deposits causing the shuddering.

I agree that the build up was from the EGR. The problem is they didn't use the low ash type synthetic oil that was originally required. Just some standard synthetic. I'm assuming the low ash part was required for some reason and I think that reason is because of the EGR. Since it wasn't used, it helped to clog the heads. Perhaps not the only reason, but perhaps a factor. am no engineer so that's just my theory.

Re: Rotella T-6 in our diesel?

The original spec'd oils for our ED's, Pennzoil 5w30 Euro L and Mobil1 ESP are both low SAPS oils.

SAPS stands for sulfated ash, phosphorus and sulfur. They comprise a significant portion of a motor oil's additive content. Sulfated ash is not added to oil; it is the result of additives in the oil burning and creating ash.

I have never been able to learn, were these new heads made standard on the 2015's EcoDiesels? Anybody have the P/N's of the new and old versions?

From what I recall from my VW/BMW diesel days, the low SAPS requirement was mandated due to the new DPF's, and not wanting to clog them up anymore than they already do.

Re: Rotella T-6 in our diesel?

So any news why this TSB doesn't apply to our 14's and 15's since they changed our manuals to the new requirement. Additionally the Rotella T6 is also a low ash full synthetic oil the only difference is now Chrysler says use the 5-40 vs the 5-30. Are they trying to protect the engine from the heat build up with the 40wt portion of that oil. It interesting that you can't get a straight answer from the dealer or Chrysler. It would be nice to have a direct line to Engineering. Those guys know.

Re: Rotella T-6 in our diesel?

You don't get any significant protection increase from 30 to 40 wt given it is already synthetic and multi viscosity. My guess is better availability and the fact that synthetic low ash seems to fit the bill for their spec. Given many of us running diesels before this ran Rotella this is hardly surprising...

Re: Rotella T-6 in our diesel?

IF change wasn't important, than why were dealers paid to change the oil in all the diesels sitting on the lots? That doesn't happen unless there is a serious need. I asked my dealer and they just smiled.

Be nice to get a straight answer. I agree Mike V, why bother change the oil to 5-40 on all the existing inventory. They could of changed it when the first oil change was due. Something there not telling us. Or like some have guessed maybe we will get a TSB eventually. I think I will write Chrysler/Jeep again.

Re: Rotella T-6 in our diesel?

I have a case of the old Pennzoil left. I think I will switch and add one quart of the old in with the new to use it up. That little bit won't make a difference.
