My bottom will usually look the same or worse at 10-15k and the top always looks brand new.
I've tested with Blackstone 6 times and now I have no fear about taking the oil to 15,000-17,500. Everything looks really good at those distances but the viscosity does start to fall below 66 SUS Viscosity. They target 66-78. Perhaps that is the shearing everyone talks about. Your oil looks good.
I put in a FS2500 and I notice the that the aluminum and Iron stay lower but the Insolubles% is the same; always .03. My aluminum is 3-4ppm and Iron is 15-30. These are 10,000 to 15,000 intervals. All the rest is the same stats as your and they tell me it looks good.
My Calcium, Magnesium, Phosphorus and zine are almost spot on with yours. Perhaps I'll the Rotella synthetic versus special ordering the Valvoline Extreme Blue. You have a bit more Moly.
I've got a some Potassium and Boron from the RevX I dumped in at 91,000 after a change.
