I think this reinforces the concept that the unburnt 2 cycle oil (and unburnt fuel) that gets deposited on the trochoid walls gets scraped off and added to the oil pan oil, and would be EXPECTED in engines running premix or 2-cycle injection reservoirs. I think it probably demonstrates that fuel from the combustion chamber blows into the pan when your side seals are smashed permanently into the side of the rotor :-) As I mentioned in the previous reply to Todd, I agree that the oil I tested would not necessarily show signs of the failure, since we can assume that most of the contaminated oil never made it back to the engine.
