I didn't miss anything. You wrote "The fuel polisher AND similar filters on the engine and generators" says nothing about oil filters. You understood what you meant but you didn't mention oil filters, only fuel polishing.
It's like hanging up a sign saying "back in ten minutes". You understand the message but nobody else does.
It now appears from what you have just written that you are also talking about bypass oil filtration in addition to fuel polishing.
Bypass engine oil filtration kits were being promoted in the 1950s in magazines such as Popular Mechanics. You could buy a bypass oil filtration system to screw onto your Ford V8 flathead. One such used a toilet roll as an element. Independant tests conducted at the time suggested no benefits from bypass oil filtration and they actually created a vulnerable location for a possible oil leak
that could lead to loss of lubrication.
There are other contaminants in older lubricating oil that all the filtration in the world can't remove.
