I haven't got anything clever to add, though I always knew there were better greases than vaseline. Does the motor axle get that hot? I am about to rewire the motor on a 201, and what lube do I buy? I have a tube of Finish Line Ceramic grease and a very old tube of Singer grease. Something with teflon? I have to get wicks and possibly carbon brushes too.
I never thought much about the melting point but; grease have a few other factors that play a role. I have thought of it like this:
1. A sort of grittiness too smoothness factor; rub it between two fingers and feel the difference between a smooth grease like Triflow or a white lithium grease.
2. A gooeyness factor; how sticky it is and how it can slow down parts compared to a light flowing oil.
3. How well it coats the parts involved during use and how well it stands up to time.
I want something as smooth as possible, with the least amount of friction involved.
