Some uos's show oxidation/nitration. Others show only the level of insolubles.
I am not convinced that uoa's can give any real indication of the state of engine cleanliness.
I think uoa's are valuable, but I'm skeptical of extended drains.
Can't a potential sludge bucket show great numbers?? I think so.
