I work in polymer research, so all this data is making me wet, but it begs one large question, and I'm not trying to be argumentative, I'm truly curious.
I would agree from the numbers that the AMSOIL filter is much better at filtering oil, no question.
BUT, is there any data to show that the delta particulate can be traced to actual early engine failure? In other words, does filtration to this level really mean a longer lasting engine, or are we just looking at better filtration that is negligible in real world driving?
Either way, this is a very interesting subject.
