Blackstone UOA Report is in

ltullos · 07-06-2019, 10:59 AM

As I track my Zs, I've been using Blackstone's UOA for a long time, and am quite satisfied. As a result of their analysis, I changed from Redline to Motul oil and have been able to extend my oil through 2-3 track events with confidence. Due to mileage variations between oil changes, I normalize the iron and copper content to PPB/mile which helps to clarify trends a bit better. My 2016 Nismo currently has ~25K miles and 5 oil changes and I'm still seeing a decline in the copper content from 900 to 300 PPB/mile (with big drop after 15K mi), while the iron is showing slight increase (350 - 500 PPB/mile).

I got nothing to do with that, as Trips didn’t have to lock.

And it was a legit confusion. Apparently dudes are chicks and chicks are dudes
