That what I was driving at, Mattax.... Kinematic viscosity of 9-ish is low for a multigrade xW30 or xW40 weight at 100c.... which would correspond with the % gas in oil number.
But gas in the oil would explain why the oil is so filthy in the OP's pix... it has really cleaned out the engine! I'd pull the valve covers and make sure that varnish gunk has not started to form. Probably not, but long term gas-in-oil will reeeealy gunk up a crankscase.
