I'm not familiar with the engine, but the wear looks minimal to me. You don't appear to have any fuel dilution issues either. That's a very good thing, since almost any engine oil will work in the engine.

There's one thing I don't understand about Blackstone: why do they use (and keep using) another SAE range?
I mean, in every SAE J300 spec I can find online, the SAE 30 ranges from 9.3 to 12.5 cSt. so its pretty plausible that is correct.
It doesn't matter if the oil you used ends up being 8.9, 9.4 or 10.2 cSt though, depending a bit on how it started.
Ask the average Joe/Jane if he/she would use "a 20 weight" in their S2000 and you would get "Thou Should Use 10W-30 Because THE MANUAL Says So!"
Oh well..
Btw.. thanks for posting this UOA.
It shows this Mobil1 stayes a 30 weight in the real world in this engine.
