Hi Ron,
I read your home-made lead acid battery in a PVC pipe post and it sounded like an interesting project for someone that wants to mess about with that kind of stuff. I was hoping that you would come back with some experimental data after a small POC (proof of concept).
And it's basically the same with your "driveline in an oil bath" concept. If you want to see if it works, more power to you. I can see a few things that may need to be addressed, like oil containment if you're driving something outside of the oil bath.
For both of these ideas, you would need to prove some advantage that exceeds the extra trouble, complexity or expense. Like you, I can "invent" all sorts of ideas from my armchair (or for me, behind the steering wheel), but getting those things to work in real life is a bigger challenge.
I've got a number of friends doing real scientific research, in fuel cells, multihull design, gravity waves, deep space spectrums, oceanographic geology, etc. and more friends doing practical reseach in EVs, blacksmithing, electric boats conversions (most of them are here), practical archeology (historic daily living techniques), etc. So I'm used to people tossing random ideas around. But unless the suggestion happens to fall into another person's area of expertise, the person suggesting something has to advance the idea with more than just a concept.
So I suggest that you continue with your experiments and let us know when some of them meet or exceed your expectations. It helps if you can state what you're trying to accomplish and how your suggestion can accomplish those goals.
And typically, free ideas are worth exactly what you pay for them, very rarely more. :)
Fair winds,

At 20v DC, I checked amp draw operating in air, the results 0.3, then in oil, still 0.3 and after almost one hour, the oil started to show a slight grey from carbon brush wear and about every 80 or 90 seconds the amp meter would move to 0.4, then back to 0.3, The next night I let it run for almost 3 hours.
