A few more comments to the post ,
A good farmer friend of mine has a 120hp international tractor that was bought new in 1972 always used conventional 15-40 oil , never even had the head off of it . Tractor shows over 14,000 hours on the meter.
My wife’s grandfather had a service station in the 50s and 60s in western North Carolina . He told me a conversation he had with the traveling salesman selling STP oil treatment . Basically he took the salesman and poured regular oil and STP in a pan , then took a torch and heated the two ..... the oil just basically bubbled and smoked turned black . The STP turned to a stringy goo that resembled taffy .... now evidently the salesman never stopped again . Correct me if I’m wrong but wasn’t STP synthetic ? Teflon?
Just like then and the same as today’s engines there is substantial amounts of heat from burning extremely clean and near zero emissions .
