In his notes he even stated "Redline oil also tested low for Zn and P in their newer SM formulation; according to Redline, it should be 1400 ppm Zn and 1200 ppm P." Again more questions then answers. I will also find out the temp ranges and post them as well.
Royal Purple is high in zinc, do you have that stuff?
