Mrs. Mouse decided to build a dandy fine fluffy nest under the cooling shroud and it over heated the cylinder and gauled the piston and cyl wall badly. That explains the metal in the oil just a couple hours after the oil change. The piston may have already started gauling before the oil change. The engine was clean as a pin inside. I always used 30wt non detergent oil in it as stated by the manual. I also used 87 octane gas as it is the 89 octane gas around here that has the alcohol in it. I don't think that oil with zinc would affect this engine as it has a nylon cam in it. The zinc additive is more for high RPM engines with heavy valve springs riding metal to metal at the lifter to cam point. It may be possible that the zinc in the oil would have helped stop the cylinder gauling, but with an aluminum block I somewhat doubt it. This engine was a 2005 so I would think if the older ones would require it, they would have made changes to the design since the EPA is now watching small engines. I know for sure in the future I will check for mouse nests before I start splitting in the future! Thank you all for the comments and suggestions. I started looking for a replacement today, hopefully one with a cast iron sleeve.
