Powerstroke 6.0 engine: What does CK-4 mean for me

[BrocLuno]

OK, I see two issues.:

1) Ford is going to run straight into the State of Kalifonia Law which went into effect this year and stops the sale of all obsolete oil formulations. That's how VR-1 got banned

2.) https://www.fcsdchemicalsandlubricants.com/main/additionalinfo/dieseloilsWSSM2C171F1.pdf Plenty of choices, but not most of the majors... In addition, I suspect that some of the indies will label the oil as meeting both older specs and newer ones ...

This is going to get messy soon for Ford Dealers who service big $$ customer trucks like some of the Winery and/or Vineyard Owners around here. I can see Nancy Pelosi and her husband (fairly powerful attorney) questioning how come their trucks can't be covered with an approved oil ... And asking Ford to resolve this ASAP

I'm not sure off the top of my head. I believe, at least sometimes, that may have to do with what specs are considered current. Imperial Oil on their sheets usually mentions approved for with the current specs, and then recommended for when it comes to the older ones.

My fiancee runs 10w30 Motorcraft diesel oil in her 2003 F350 with the 6.0L that she bought new. She has used this oil since the truck was new and plans to keep running it.
