While I have heard many good things about Synergyn's oils, I believe they do not contain any moly additives. I am beginning to believe that moly additives are pretty useful within motor oils, thus they may be helpful within the Synergyn oil that I am now using. I just switched to the Synergyn product (5w-30), would any of you guys recommend adding a moly additive such as the Schaeffer's products to this oil ?. Or would this be a waste, possibly interfering with Synergyn's proprietary additive package ?. The car and oil would be used for daily driving and occasional track days through the summer months. Any advice would be helpful. thanks !
