that engine looks extremely happy running that stuff. I'd probably opt for a TBN if I was doing 10k changes, but otherwise, keep it up and great to see a beautiful car having the miles put on it like its intended.

You added 2Qts, did it need a third when you changed it?

Have not changed it yet. Have been driving the salvage 2011 S550, so this one is just sitting waiting in line for work.....

The oil analyis stuff is very new to me. The main thing I am looking for is if the analysis hints at impending engine issues. Two things I am most looking for is coolant in the oil and metals. And I say this from a very amateur point of view.

not important, when it shows up on a UOA it’s late. pay for TBN and see how much you can stretch the oil out

that engine will make it to 5 quadrillion miles with half a quart in the pan it’s the least of your worries

Used Oil Analysis is that: oil analysis.
You have to developers trend, several oil analysis to figure out are there issues with engine, how certain oil affects wear etc.
