Weird that the 2020 supplement contraindicated itself stating first to use Shell T6 and then at the bottom to use Pennzoil Euro. Both require the correct MS and API specs however

I think we basically determined that the original 2020 manuals that came out late 2019 with these trucks were erroneous. They should have omitted the old info but didn't, and accidentally left it in there along with the new and correct info. The second revision corrected that in the manual.

Yeah they definitely did. My 21 says to use Mopar or any SN that meets their spec 🤷🏼‍♂️

OK, so what should we be using then? Is the consensus that shell Rotella T6 is still OK?

Not from what I can determine based upon FCA requirements. The "approved" oils that I can get which meet the MS-12991 and API SN spec are as follows (there are others, but these are what I can readily obtain):

Pennzoil Platinum Euro 5W-40 (https://www.amazon.com/gp/product/B07TXFCC3Q/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1)
FRAM Full Synthetic Euro 5W-40 (https://www.walmart.com/ip/FRAM-Ful...V4vbjBx2AeAzEEAQYASABEgIR3PD_BwE&gclsrc=aw.ds)
Quaker State Ultimate Durability EURO 5W-40 (https://www.autozone.com/motor-oil-...VevHjBx3RlQ3OEAQYASABEgKMYPD_BwE&gclsrc=aw.ds)
Mopar 68231020AA 5W-40 (Bottom of my list due to the ridiculous price the dealership parts department charges for their unicorn oil)

I have yet to find anywhere that T6 is approved...a very, very good oil in my opinion but it doesn't meet MS-12991 and API SN.

Thank you for taking the time for that excellent response 👍

FYI the Quaker State oil is typically found at Walmart for $18.97 or less per 5-quart jug. And it's EXCELLENT oil per my latest oil analysis. I beat the snot out of that oil for 6,300 miles and it help up amazingly well. I'd put it up against any "luxury" oil on the market.

Agree. I’ve used it as well for my first two oil changes but now can no longer get it at any of the Walmart's within 100 miles of me...or online. So, I resorted to ordering Pennzoil from Amazon at a higher price and hope Walmart stocks it again.

For any Canadian Ecodiesel owners. I've been using Motomaster 5W-40 from CT. From my research it's basically rebranded penzoil. It goes on sale for $22 for 5L about once a month. It meets MS12991 spec.

You can tell from the really bad quality that I actually made that myself, and it wasn’t my 2 year old son.

I tried it once...it changed the sound of my engine...I had to immediately change it and have never purchased it since then.

The normal "Cackle, cackle, cackle, cackle" sound of my diesel disappeared and then it started making a sound like "Cackle, eh? Cackle, eh? Cackle, eh? Cackle, eh?" ;)

(No disrespect to my Canadian friends...some of the best hockey I ever played when I was younger was with my Canadian neighbors.)

That may be what I end up running if I can find it around. I'm an amsoil preffered sucker for my hemi, so I'm debating on using their euro oil even though it doesn't say ms 1299 or whatever that code is. If your running a good 5w40 synthetic, you wouldn't think they would fight you too bad if she blows up

I bought this one because it is MS-12991 certified for our ecodiesel. I couldn’t pass it up when it’s double the price on Amazon.
