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...
Does anyone have any experience with this oil?
