So Im wondering and I see the same concern here and there... What does the Ck-4 mean for my semi older motor? By that I mean what does the new Ck-4 mean in terms of longevity? Id assume they arent going to make a CJ-4 ONLY ( or at least up to CJ-4 ) oil. I seen a discussion about people saying the same thing when CJ-4 came out.
What also has me some what worried is that Ford supposedly ( I have to double check the thread here to see if it came to a head or not )said to NOT use the CK-4 oil in their 6.7l. Its a new oil cert in a NEW truck engine ( well relatively new )
Any words of wisdom?
