I guess the engine makes a pour refinery at separating the oil and fuel, once they are mixed together in harmony and synergy.
I have a feeling that the amount of fuel might be excessive. I don't want to believe the automakers didn't notice this with their GDI tuning. They also didn't notice LSPI, IVD.... and the list goes on.
The question you should ask... HOW MANY GALLONS OF FUEL MAKES IT INTO THE OIL SO THAT THE UOA shows that 5-10 ounces not evap'd at any given point? and would you notice it?
My wife drives 4000 miles and uses 200 gallons of fuel. Would I notice if it was really 199 gallons or 201 gallons? I won't guess at the accumulation or evaporation rate. How many gallons of fuel do you think you're oil and PCV are processing continuously? Then, be scared. Gallons might be blown past your rings over your 10k or OLM interval.
That is mind boggling.
Poor fuel economy too.
