So exactly what in that UOA says the oil filter was doing a good job?
If it's the "insolubles %" it's not a good indicator of filter performance because if you compare insolubles to an actual particle count they do not correlate at all.
Your statement conflicts with Blackstone's own language on it's website regarding it's insolubles test.
BS: "The insolubles level indicates how fast the oil is oxidizing and
how effectively the oil filtration system is functioning" ...
Blackstone
The lack of wear metals, the fact that the oil is still in grade and low insolubles is
circumstantial evidence of good filtration. (no oil, no matter the quality of it's base stocks or add pk, can cover up for poor oil filtration over a 5k mile oci)
You think Blackstone has ever correlated "Insoluble %" data to particle count data on the same UOAs to see how they compare? I have from UOAs posted on this site, and I see no real correlation at all between the two.
