Every couple oil changes I have started sending a sample to Blackstone Labs to track engine wear over time. These are from my 24 3500HD that I got back in May. I use it haul and tow quite a bit. Both on the farm and in construction. So it sees the full spectrum of conditions. I use Mobil 1 Truck and SUV. The original test was on the break in oil. Thought I would share so everyone can see break in oil vs a normal change. The TBN was high enough that they said I am safe to run 7-8k on the next change.

I've tried searching for this, but came up empty so far. So I'm hoping someone may have seen or heard of this one. For years my 06 Tahoe Z71 4WD 5.3, would properly reset the oil life back to 100%. Now for the last 2 oil changes it has decided that it doesn't want to. On the previous reset attempt it would only reset to 82%. On the most recent Oil Change it only reset to 52%. This isn't really a big problem just quite odd. I did note that when it only reset to 82% that it still took the same 10K or so miles to get down to 0%. Of course when it didn't fully reset the first time I reset it several times all going to only 82%. Now that it's only resetting to 52% I'll have to see how it does.
