Amazing as it sounds, it really does happen...

There is so much fuel in the engine that it bypasses the metal oil control rings and the oil control o-rings.
Remember, Mazda designed the oil control ring system to keep oil out of the combustion chamber.
Oil is significantly more viscous than fuel.

I have a feeling the oil control rings are just "hydroplaning" over the gobs of fuel inside the engine in a disgustingly overly rich condition, which allows the fuel to eventually enter the oil supply.

I've drained oil pans where the "oil" flowed as thinly as water...
You can smell the gasoline mixed in with the oil too.
