If it's smaller than 20 µm then likely most of it will pass the oil filter. I don't think that's a good thing or it doesn't even matter.
My first thought when watching your video. I used to shake any bottle before, but I will have to rethink this common practice. That said I have never observed anything settling out yet. Perhaps your old Shell example is a rare exception? Even then the result of your OAs remain true anyway. Common additives do not settle out. Thank you very much for your effort.

Re whether it's damaging... Yes, if it were as big as 20 that could be a concern IF there was enough of it to worry about. But some will get trapped by the filter, some will settle out and that's from a starting point of there probably being less then 66 ppm of it. It's not something I would worry about because there is so little of it to start with.
