QSport is correct. Also the synthetic oil vaporizes, not evaporates, That is a huge difference as vapor has many saturated droplets and evaporation implies that the oil becomes superheated with no droplets. It does so as the fuel burns, so there is still plenty of oil on the rings because the oil gets there from the crankcase around the piston and from the bottom. Think about it in a four stroke engine all of the oil is in the crankcase and the rings are lubricated from oil sprayed on from the wrist pin or vapor from the crankcase.
