Would also be interesting to know more about what’s driving the high TAN.

Manufacturer data sheets are showing the typical values for that oil. There will always be manufacturing variances and we don't know what those are.
Blackstone's own testing has a margin of error, too.
I don't think that starting TAN is very high. I have seen plenty of VOAs come back with TAN of 4-5. Certain basestock types can cause elevation of TAN, if I remember correctly.
