It seems to me, from what I have read about it, that Ford changed their own specs to keep us using the motorcraft brand. Shell is working to develop a Rotella formula that we can use but then again Ford still gets the final say if they approve or not.

when is the forum going to get fixed?????
Don't think so. Ford says the new spec coming out is not suitable for their product. CJ-4, the most common diesel oil spec is suitable.
Ford does not manufacture motor oil, they buy and rebrand from any number of suppliers.
Shell Rotella has been a CJ-4 oil for years.
At issue seems to be the additives. And I think it has to do with European applications that the oil is changing.
