May want to send a sample to Blackstone along with the oil filter. That's the only way to know for sure what it is.

If you don't want to bother with it, could at least open up the filter and see what was in there. Interesting article to suggest that https://www.blackstone-labs.com/oil-filter-testing/

  • Filter analysis is something you can (and should!) do yourself, to get a baseline idea of what’s normal. All engines produce metal; the trick is to know what’s normal and what’s not.
  • The debris we find in filters tends to fall into three categories: metallic, carbon pieces, and unknown. Some metal and carbon is okay.
