Oil was changed at the time of this sample. I haven't posted in a while, looks like something changed as I can't get the format to look any better than this. Sorry.

Blackstone Comments:
Steady does it for your Duramax. You kept this oil in use a little longer than last time and wear metals hardly changed. That suggests internal parts are wearing as they should and the longer interval didn't bother them one bit. No air or oil filtration problems are suspected, and we didn't find any fuel or water to note. The TBN shows lots of active additive remaining in the oil so try going 26-27K miles if you'd like. Based on the established trend, we won't be surprised if your Duramax handles that interval really well. Keep up the good work with your 6.6L. It looks great!
