Any input on this oil? It is 5w40 and says it is API SN. It is the only oil that is in stock right now around me and i am past due by a couple hundred miles for an oil change.

I figured it would be OK and since the MS-12991 isn't "recommended" anymore anything API SN certifed would be good. However, i just noticed that on the Mobil1 website it says for diesels without DPFs. But I take it this is just like how the R6 Rotella oil is said to produce more ash and not technically "approved", but people and apparently some dealers use it haven't had any issues.

Can you please provide more information to this statement:

“MS-12991 isn't "recommended" anymore”

My money as to why their website states not for vehicles with DPF’s is likely because it’s a very High SAPS oil.
But to be fair…. I have never understood how pennzoil platinum euro ever got the MS-12991 ?? with its SAPS levels either ??‍♂

Sorry, i mistyped. Meant to say isn't required. There was an update to the manual that originally stated that MS-12991 was required. But in 2022 it was updated to say recommended and that 5w40 oil with API Donut cert of API SN or SP can be used.

Which is similar to the R6 as well, since they said that the ash content levels are higher but the number is minimal on the analysis report.

My question is, why are we using oil designed for Gas motors? Oils specifically designed for diesel motors further address dispersants that provide maximum sludge and deposit protection. I've always had an issue with this. Maybe from owning and/or driving diesel vehicles for years and accumulating well over a million miles in them.

Any thoughts?

I think it has more to do with where the motor comes from and the parent companies origins. In our case FCA/Stellantis and the VM sourced engine are of European origin. In Europe, it is more common to have single spec engine oils for passenger vehicle use and in the case here, a Euro Spec 5W-40 would meet the requirements in Europe for dual use. FWIW, MS-12991 is older FIAT gas engine oil spec.

I know there is a balancing act in engine oils either for gas or diesel in the amount of sulfated ash, phosphorous and sulfur (SAPS) content. Sulfated ash is basically the percentage amount of oil that remains after burning it. In gas engines, that ash to a certain degree is consider a lubricant for valve train wear but in diesel use is considered a dispersant that has to be controlled to avoid DPF and emissions issues. The main driver that pushed the API SP spec and differentiated it from the SN spec is that SP when to a lower SAPS level content. For Gas engines, this catered more to the Direct Injection crowd and by default would lower the amount sulfated ash in diesel engine use.

All these light duty truck diesel oils are strange. The JT’s being 5w-40, my Silverado diesel requires a 0w-20 D spec oil. Blows my mind a 0w-20.

One of the best things anyone can do is to pull an oil analysis at each oil change interval. That way you know what's happening inside the engine as well as the condition of the oil. Without a question, the gen 3 EcoDiesel is hard on oil.

Just read 24 pages, good info here. My 2020 JL got wave changes with Mopar oil and the Penzoil after dealer couldn't get Mopar anymore. I bought it new and it has a little over 70K miles on it now. My JT has 6,500 miles and I changed oil at the one year mark using Amsoil 5w-40 EFM and will continue. If I read correctly the Amsoil AFL 5w-40 is a better choice. Since my JL is out of warranty would the AFL be a better choice for the JL?

Correct. Amsoil SAE 5W-40 MS (AFL) has held up better than any other oil we've seen. I'm still running Pennzoil because I bought a bunch of it for cheap, but the Amsoil MS holds up better. The Pennzoil Platinum performs just as well, if not slightly better, than the Amsoil EFM.

Good to know. I will have an oil analysis done on the 70K mile JL and post it up here.

Mine is mostly towing mileage, but at least you have something to compare it to.

Are you running GDE ? Have we seen any further data on the concerning aluminum # from gen 3? I think my qs euro numbers were decent for ~5000 miles.
