Blackstone Comments:
You've got another great-looking report here. There's more metal than last time, but that's okay. What we're seeing is just normal accumulation from the additional use, and we can tell that because metals have barely budged on a ppm/mi basis. Your Duramax is still wearing well with over 200K miles on the clock, and we don't see any indication of that changing soon. The sample's physical properties also did fine in analysis. Its viscosity was in spec for the grade, no fuel or coolant was found, and the TBN of 6.2 shows plenty of additive left. Nice! Try 22k miles next.
