Hello Guys. Before I say this I know I know "Don't worry about additives just use the cheapest quality oil that meets the specs of the engine". Now that is said. I currently work for an independent shop. The owner is very knowledge able and an AMSOIL dealer. Loves AMSOIL and JB products. He has been using JB products for 30 years with out having any issues. The JB rep came in the shop the other day with a new product. Its called ENGINE OIL SUPPLEMENT. He also brought in a bearing friction test machine, where an electric motor spins a bearing and a metal bar is applied with weight until it stalls out. I've never seen this before. He used oil from around the shop amsoil, Pennzoil, mobil etc. On the second plate of weight the bearing stalled out with all the oil ok. He then applied this oil supplement to the various oils (also did the same thing with the engine tune up) and the was able to put maybe 6 more plates on with out it stalling. Does this test make sense? Is there any value to this product? What are the potential issues that could arise? It was an impressive test. But it may only be impressive to myself and the techs in the shop because maybe we do not understand what is really happening. Any information or explanation would be helpful as I'm really trying to learn all I can. I have common sense but I'm no engineer and admit when I'm ignorant.
