A few months ago I changed the oil in the BX 1850 and noticed a few black specks in the bottom of the pan. I wasn't very careful about cleaning the bottom of the catch pan so I couldn't be sure it was coming from the tractor.
A couple days ago, I made sure the pan was clean before I drained the crankcase and it was the same thing. Black specks that look like crumbs of burnt toast. I isolated several of these for a closer look. They are easily friable. I can crush them with my thumbnail.
I'm guessing that this are agglomerates of engine soot. The engine runs great, and there's no indication of power loss or any real trouble at all. The tractor has 590 hrs on it. I use 15w40 oil. Either Shell or Valvoline.
Anyone else notice this?
