I asked Blackstone about their take on different oil filters because here the focus is on efficiency, but UOA only looks at insolubles. I know it’s been said that 10-20 micron particles cause the most wear, but it seems like if it was that important, it would be part of the UOA testing. We are, for the most part, casual UOA uses, but large companies can save or lose thousands or more based on these tests. Even the military does UOA. Seems to me if fine filtering was so important, it would be A standard test.
Blackstone responded by basically saying they don’t track filter usage. They pay attention to the insolubles.
