I think you're misrepresenting my position a bit. I'm not saying it "can't be true" or that the OLM can't be off, nor am I claiming that they're perfect, but in this case we ARE talking about a different engine! The cases of OLM's being miscalibrated are pretty well-known (certain DI engines and the Honda VCM engines). Besides that, if you have a new engine design then I certainly understand being conservative until there's documentation out there or you do some UOA's yourself.
Regarding Dermapaint's hypothetical on the used car, the funny thing is that I'd rather the PO have done short OCI's--but my reason has nothing to do with the oil's suitability for use. I just wouldn't trust the PO to have checked the oil level, and more than anything I think that driving around without enough oil is the most damaging thing you can do to an engine. So, if you happen to have an engine that consumes some oil and you never check the oil, I can see problems developing over the course of an OLM cycle. But again, that's a hypothetical that doesn't apply here (hopefully!). If you're doing longer OCI's, then I'm assuming that one is checking the oil level regularly and topping off as necessary. If there's one argument against average owners doing longer OCI's, it's that one, IMO.
Oil quality is obviously an issue as well, but all of the SN-rated oils seem to hold up well, including conventional oils. I'm not sure if that's what was used in this case, but if so I'm not sure I'd be too concerned about "conventional vs. synthetic". All of the GF-5/SN-rated oils seem pretty robust.
