The T4 Rotella still meets that Ford standard. & I don't have a Ford tho.

So it is my understanding the T4 is still as good as it was..

Cpurvis- I know you & I had discussed this in depth.. Maybe that was what you referred to ?

Yes, we did but I can't find it now. Maybe it was in a thread someone else started?

You're right, it was in a PM. I'm going to share a bit of it here in case tom3 is interested:

Interesting stuff. Rural King's Harvest King 15w40 oil is listed for Ford, 5 gallon bucket under $40. Listed as CJ-4 SM. Might be an old listing though? This oil deal for older and non-automotive engines is a mess.

Hoping I've solved my problems, Rotella for the twins (and old Camaro), Delvac 30 for the small motors. Note the API SF rating. Anyway I think I've quit looking.

We still have to remain vigilant. Once the API decided that the CK-4 rating didn't have to be backward compatible, everything changed.
