Well not what I expected, I emailed the lab to see if they did some type of dilution due to it's viscosity and about the aluminum that is present in the sample. These numbers do not match anything prior as far as the Zinc and Phos goes. Now I wish I had used Blackstone. Zinc 684 and Phos of 655 seems low from other samples I have seen that are in the high 3000 range. I'll have to see what they say about this, but with these number it would be like adding SN 50w oil to your oil using this and very pointless.
