Hello Talker, I was made aware by a forum member of a product, which is added to the oil, a kind of ceramic coating in the engine block. I can still remember older advertising shows, in which the guys also used such a product or similar and partly had machines run without oil and water… well.. Advertising just 🙂 I got the broth for my oldie (70s Mustang Coupe V8), but wanted to get ahead ask again if someone has had experiences with it and if so which one. The product is called Ceram-Flow and comes in a small (estimated 250-300 ml) plastic bottle WITHOUT instruction manual. So if someone has experience with this or similar products – please report.
