Mineral oil sounds good except...
- low materials compatibility, known to eat plastic and eventually delaminate circuit boards over a long period of time
- breaks down / oxidizes faster than most cooling oils
- smoke point at 135C, kind of low for a hub motor
- more toxic
- carcinogenic if not extremely pure
A lot of people building high performance computers who have used mineral oil had components destroyed after a number of years and concluded is it not worth it.
I say that since we have close to the same variety of materials as a PC, mineral oil is not suitable long term for a hub motor.
Looking for something like opticool or even better.
