Oldchevyguy, this is one of those topics, like "Unsticking" rust-seized engines that generates a range of "opinions".
It would be very interesting to know what the qualifications are of the people expressing the opinions. Lubrication engineer? Metalurgist? Chemical engineer? Auto museum curator? Reader of Popular Mechanics?, heard the answer from Skeeter and Bubba?, other?
If I were seeking an answer to this question I would call the technical department of one of the major oil companies. They have been very helpful to me on other items like guiding me to the correct lubricants for the Vega steering box in my roadster street rod and the U-joints in my daily drivers.
