Need help guys. How do you find the right oil standard of MS- 12633? It's not on the jug.

It will be listed if it meets the specification. Mobil 1 doesn't meet it, nor does Castrol. The only ones I am aware that actually meet it are the Pennzoil Ultra Platinum, Redline, and the Amsoil.

I know I have used Castrol as do a pot of the other 6.4 owners on here. But my dealer is the cheapest on the Pennzoil if I go that route.

It’s usually listed on the back. Mixed in on all the fine print that older guys can’t see lolololol

and according to their website, CAM2 makes an 0W40 that meets the FCA spec. I use M-I as in the pic above with MOPAR filters in our truck and car 6.4.

Euro M1 does not meet the spec.

Penzoil Ultra Platinum (PUP) or Amsoil does.

PUP can be found on Amazon, NAPA and others.

There may be others.
