So they did do their homework on fluids. Who'd have thought.

UOA will not count particles that you can see with your naked eye. If there are more visible particles after second change I would be very worried. even for break in period wear on that engine looks very high

How can you have particles that big without at least some indication in a UOA? I could see it happening if the UOA were normal, but this one is apparently much better than normal. Not necessarily disagreeing with you, by the way. Just interested to learn.

UOA can only "see" up to 10-15 micron, even less depending upon method used.
