I have not done any more yet -- I have only had one oil change between the one on this original post, and the oil in the sump now. I replaced the lifters this oil change, so I'll probably run analysis on the next sump full. So probably in about 2020 since I only put about 4-5k per year on the Benz.

I think the wear metals was from the new vacuum pump and possibly lifters. I will definitely post it up when I get another one done. Right now I'm sorting out a failed alternator and some nailing and leaking delivery valves.
