I have done quite a bit of reading, and had extensive conversations with the sales lead for a major oil analysis machine manufacturer. I am a bit worried about the modern oils, and in recent years the removal of additives deemed to be environmentally unfriendly. These additives were responsible for the lubrication of the lifter flat surfaces not present in modern engines. The oils manufactured today are not the same as the ones manufactured 3 or 4 years ago. I have good friends in the business of rebuilding antique engines. They have seen failures recently in antique engines run with modern oils. The information is out there for those who want to learn more about it. I am not pitching any product, I'm looking for advice and experience from those who have taken the time to look into the lubrication alternatives required for antique engines.
