This seems like a question that someone here might know the answer to.
One of the popular high zinc "classic car" oils is Brad Penn 20W-50. I've often seen it referred to as the "old Kendall 20W-50" and it's dyed green.
Does anyone know if Brad Penn and Kendall are associated with each other? As I said, I've seen this repeated quite often in reference to that specific oil, and I'm wondering if there's any real truth to it.
Brad Penn at least is not an inexpensive oil at least as conventionals go-it runs about $80/case. Even though it comes highly recommended, it's one of the reasons why I use VR-1 instead(the other reason is that I don't have to order VR-1).
