Resinification (chemical reaction of the oil with oxygen)...
...has receded more and more into the background since synthetic oils and mixtures were used, the exact composition of which was known and which no longer oxidized. From my point of view, the dry running of the pins in the bearings is the main problem. This can be caused by the slow evaporation of individual oil components and the resulting change in flow behavior and viscosity of the oil. Sometimes high speeds of individual components also exert a centrifugal effect on the lubricant, so that it is driven out of the bearing.

Watch lubricant deterioration - a function of time or wear?
We all know that lubrication deteriorates over time, hence the need for servicing of mechanical movements. However, I am curious as to why this deterioration happens. Is it simply that the oils gum up over time due to chemical decomposition of some sort? ...
I thought this was a nice article. One point of mention in it is that a synthetic oil past it’s useful life will evaporate.

I didn't consider centrifugal effects
But that makes a lot of sense. I appreciate the insights!
