They changed the manual I believe in 22. Ms12991 is recommended but any 5w-40 with API sn or above is fine.https://shop.valvolineglobal.com/co...n-vehicle-full-synthetic-motor-oil-sae-5w-40#. Not seeing where this meets spec?
I am reading this to be any 5w40 with ms12991 “and” api sn or api sp…. Still required to meet ms12991…. The only choice portion being sn or sp…. Not 12991.They changed the manual I believe in 22. Ms12991 is recommended but any 5w-40 with API sn or above is fine.![]()
Idk , I just find it more important for an owner to balance their concerns based on the motor and it's requirements. Cross shop some of the MB 229.5 and 229.51 specs with ms12991. A lot of the requirements are based around sulfated ash and issues with the dpf. Low vs high saps. Our brothers n sisters over on the JL side had the same discussion. https://www.jlwranglerforums.com/fo...-0-ecodiesel-jeep-wrangler.44439/post-2328460I am reading this to be any 5w40 with ms12991 “and” api sn or api sp….

Agreed. Rotella T6 is the best, universally available, inexpensive oil option.run t6
I have read of a few folks with GDE tunes coming back with high fuel dilution…Idk , I just find it more important for an owner to balance their concerns based on the motor and it's requirements.

Gde who I would argue knows a lot more about these motors has mentioned run t6 in theirs which doesn't even meet SN anymore.
Yea I had mine reflashed actually, but my dilution wasn't an issue with 6-8k intervals on both pp and Qs on the lab reports.I have read of a few folks with GDE tunes coming back with high fuel dilution…
I understand the weights and balances of saps longevity of motor>longevity of emissions equipment….
T6 has had to remove several certifications from their oil over the last couple years…. Suppose this is a you don’t discussion, as interpretation of results very….
How many miles and oil changes on the truck? I'm glad someone's running tdt. I was looking into that vs delvac.Mobil 1 Turbo Diesel Truck oil 5w40. Just over 6,000 miles on the oil.
My oil report came back good for most everything. The only 2 things that stood out. The aluminum level went up from 12 to 19. The potassium went from 1032 to 1134. The report said that the it could be from harmless flux off of the EGR system. And they should trend together if that is the case. But can't rule out piston or bearing wear. Fuel was less then .05%. And to resample in 6,000 miles.
Mileage when that sample was taken was 34,266. 3 Jeep Wave oil changes. Have no idea on what oil they used. And the last 2 I did my self.How many miles and oil changes on the truck? I'm glad someone's running tdt. I was looking into that vs delvac.
