I received our annual oil samples from our mains back today. We boat in fresh water on lake ontario, and these are RWC engines. We are seeing elevated sodium ( 103ppm port and 106ppm stbd) The only place I can think this would come from would be the AF used in winter layup. All risers and manifolds are less than two years old. No trace of water in the oil, and the engines run fine.
Is it possible it's just the oil? I use the Merc 25W-40 non synthetic. Anyone have any samples using that same oil?
