I think you are a rare breed. Assuming from your previous posts, you went the extra step and *actually* had analysis done. That's great for one salient reason:
It will catch things that no OLM will ever monitor for. They're not some electro-chemical-mecha-optical-clarity-conductive gizmo. It's an egg timer that slips ahead a little bit if your driving conditions aren't 100% laboratory bench perfect.
It cannot account for oil grade, type, fuel composition and just plain old in the wild conditions and physics. It cannot account for engine variances, filtration schemes and failure modes of the engine itself. (Bad PCV, a little too much water in the fuel, oil-coolant contamination from failed gaskets/ seals/heat exchangers)
Best weapons you've got is diligent maintenence, inspection and follow your gut feelings and service often and timely. If you have the resources? Analysis will go miles to filing in the blanks and spot things you can't see. Barring all that, stick to quality materials and honestly... .>...
I don't know any engine, great or small that suffered from keeping filters, fluid and oil fresh and clean. None. What takes them away reach time? Neglect. But now I'm preaching to the choir, I just realized where I am.
