As promised my report from Blackstone, 850 mile break-in oil change.
BlackStone oil analysis

So it looks like you're way above "universal averages" for Aluminum, Iron, Copper, Molybdenum and Silicon.
I had a Blackstone analysis done on a new motorcycle I'd purchased (2005 BMW R1200GS) and it was similarly high. My understanding is that break-in oil change analysis is always high in certain areas as the engine machines itself into shape.
It'll be interesting to see how the analysis compares at 5,000 and 10,000 miles. In the case of my motorcycle, it settled out around 15,000 miles.

It does seem like good practice to do an early break-in oil change rather than waiting 10K miles. Seems odd Toyota wouldn't make this recommendation in the owner's manual.
Here is my 'break in' oil analysis at 974 miles.
So what exactly do you guys do with this info? Is it just educational?
I've used it with most of my vehicles over the years to watch the health of the engine. Very useful to tell if you have any intake leaks or bad air filter (high silicon), unusual bearing or engine wear, coolant leaks etc. as well as whether my oil change intervals can be extended or are too long.
I find it especially useful for new vehicles to me (used) to check condition, and have found that it helps greatly with selling a vehicle (having record of maintenance and proof of internal condition of the engine).
It’s kinda feeding our OCD.. and gives us reassurance, in this day of YouTube, forums, etc, so that we can put our worry beads away. For a little bit anyway.

Thanks for sharing.
So I changed my oil first at 1200 miles and my second just before 4K.
Just received this morning my first oil analysis from my 2nd oil change -Slightly stressed over fuel and flashpoint which I’m assuming is related to fuel in oil.

80% of that debris is in the oil pan by the time you've taken delivery of the car because most of it happens right off the bat at the first cranking. Toyota doesn't recommend changing it out because it isn't dangerous just sitting in the oil pan. The oil filter (15 micron-ish pores) is preventing debris of a harmful size from getting to your bearings (30-50 micron-ish oil clearance). The oil lubrication properties are still good.
I know I probably worded that confusing- this was my second oil change.
I didn’t do an analysis on my first oil change, so this is technically my first analysis results, but for my second oil change. I had hoped it would look better since I changed it early on.
This sounds as though there is a portion of oil in the pan that does not recirculate. True?
Thanks for that info!
All of the oil will continue to circulate. The debris in the oil will either settle to the bottom of the pan or get pulled to the filter. But it won't go back to the main bearings unless it is smaller than the pore size in the filter. If it is that small, it's pretty safe to say it isn't harmful. Again, we are talking about 10s of microns. An average human hair is ~100 microns for scale.
