Hi Wallace. You're basing all you scenarios on the oil, but the oil level, quality, viscosity, etc should have no 'bearing' (pun intended), because the bearing is sealed and has grease in it.
One thing the oil CAN do over time is become acidic and break down the seal and eventually wash away the grease.
From what I've read, lubrication is the major factor, but it has nothing to do with the oil level or viscosity, it has to do with the bearing losing its grease. Which is why some solutions use an open bearing and constantly pump oil into the bearing, whether it's from an external line or through the IMS tube itself.
