I'm not sure what makes this oil analysis so special. Show us a trend over time, not a snapshot in time. Did the oil viscosity continue on the low side? Did that cause wear metals to trend up? How can Blackstone recommend pushing the drain interval out to 7500 miles? Based on their UOA the oil viscosity dropped from 10.3 cSt@100C (AMSOIL data sheet) to 8.32 cSt@100C (Blackstone results), also the flashpoint dropped from 446F to 380F. If it was me, I would like to know why that was happening before I tried going further on an oil change.
