I didn't say that M_O_M.....
I did say that there are some CK-4's that have additive packs that mimic SN gas oils.
I do find it interesting that Valvoline, (especially recommended by Cummins, and for 5000 mile extended drains on top of OEM) has decided to stay with a stout add pack, (for all practical purposes, CJ-4 minus about 150ppm of Phosphorus,) and have both boron and moly in their mix. Could it be because of the Cummins recommendation?
Shell is good on paper as well, minus the moly. OTOH, Delvac looks like a gas engine mix with their CK-4, and one that doesn't even look as good as SL oils from years back. And yes, I know the final mix is what counts, but dang, some blenders cut the add pack to where the bone shows.
