Don't misunderstand my rant, I respect science, research and people who are knowledgeable in the oil product disciplines. I just don't see any proof about their conclusions regarding diesel oil use in the Model a Ford at this time.

I could not agree with you more! One would think with the hoard of engine rebuilders and repair/restoration shops there would be one that would say this or that oil causes failures. I respect their recommendations and would only use what they recommend if I had an engine built by one of them. But like you say Leo, no documented evidence of harm.

To all of you reading this, please use the oil that makes you happy. The oil that will get you out and drive the car often.
