Here is an update (note that I had about 6 track days on this one):
MTROIS: Lead is still reading a bit out of line, but we aren't considering that to be a new issue since it held pretty steady this time around. Lead typically shows bearing wear, but if it were a problem, we'd expect to see excess iron, copper, and tin in the used oil as well. Lead can also be introduced into the oil through leaded fuel or fuel additives, though we typically see much more than this when that's the case. The small trace of raw fuel dilution isn't cause for concern, and the viscosity was correct for 10W/60 oil. Watch the oil pressure and resample to monitor lead.
Another report to follow shortly (sorry, I am behind on my "Forum Duties"!)
