Actually the first 2 UOA are mislabelled above. This is correct:

I'd go with a full oil fill of the M1 15W50.

It looks like you probably had a particle streak that is now clearing up. Copper also increased (which is to be expected with bearing wear) and has not yet come back down to the levels of your first UOA.
Results between different oils can't be directly compared and there isn't a lot of trending data here, but that's what my novice eyes are seeing with your reports.

I'd agree. Switching brands isn't going to "fix" things if lead was elevated for a serious reason.

That's exactly what I did. I'll report back in 5000mi ...

I just love the car, mine may have as many miles as yours (ODO was broken when I bought it), I'm interested in reducing engine wear, and generally thicker oils do just that.
My 240 runs and drives great, I plan to keep it for another 20+ years, and if simply choosing one oil over another will help it perform optimally for all of those years ... that's easy!
