Default RE: 4C crank case drain

What does OS recommend for oil content on their ''new'' 4C engines that have the PCV built in?
I just looked up all the latest OS four stroke engine specs and they all are spec'd for 18% oil in the fuel.

Not surprised buy that number. You know they want the engine to live forever. As mentioned before some engines (car) use extremely low oil contend and seem to live a life. I know the car guys run the crap out of their engines and do rebuild often but I'm thinking they are running in the upper teens for RPM.

Anybody else out there beside bogbeagle running reduced oil fuel in their 4C with an oil return?
