not sure if this has been covered. Just saw the new jugs marked ck...I noticed they are no longer marked SM. I wonder why they let that slide? The new DELO 5w40 is marked CK and SN.
I like to use rotella in a lot of my OPE and in my generator and other air cooled engines. Why the move away from S rated oils i wonder?
