CJ-4 ok in 2014 Cummins 6.7?

[jdw1222]

Have some cj-4 rotella synthetic 5w-40 left
Over. Can I use it in a 2014 6.7 or do I need to use a ck-4?

 

[UNC054]

Yes you can.

usually I'd read the owners manual for that sort of information.

But since that truck came out before ck-4.. the answer is easy.

I'm pretty sure CJ-4 was the standard when it was released CK-4 and FA-4 didn't come around until like 2016 or 2017 I think

Thanks! Couldn’t Remember when I picked up the oil

CES20081 covers CJ4. CES20086 is CK4.
