Trucheli, comparing my old reports to yours, at about the same mileage (20K) and interval (5K), my wear metals are very similar, for Alum, Iron, and Copper. The notable difference is iron. You are at 8ppm while I'm at 5 ppm. I do run a billet magnetic oil drain plug from L&N Engineering. Just an idea if you like this kind of stuff and want to experiment.

Do they make one for the 991.2 that you don't have to keep replacing?

We have made billet replacements before for the 991.2. A 2.5 quart deep sump is in the works and will have two magnetic drain plugs fitted rather than one single plug, like our current billet 9A1 pan.

This was the first one fitted at Flat 6 Innovations beginning of 2018.

For comparisons, you can search for my UOA thread and find data going all the way back to 2014.

Will be interesting to compare levels of metal in the same M1 5w/50 from 3 different engines.
