Looks like something broke loose.
Was this the first time for M1 5w-20? Was it a different offering from what you were usually putting in there? That might explain the crud. Most don't see it, but transitional consumption (that may or may not accompany a change in chemistry) occurs on occasion.
What I'm saying is that I'd have a hard time figuring that this was the "every OCI crud level" in any engine. It has to be a transitional thing (probably) due to some change in oil chemistry.
