Need to replace the oil in an Aquabot pump, and am choosing Mineral Oil over much more expensive Compressor Oil, FR3 or other special purpose oils.
Having said that, there is a choice of 100% Mineral Oil which will make me wait a week, or food grade laxative 99% Mineral Oil with 1% Vitamin E as a stabilizer, which is around the corner.
So the question is, will the addition of Tocopherol (Vitamin E) to the mineral oil affect the non-conductive nature, or otherwise be bad for the pump?
Another point on the motor plug & thermal expansion:
It seems the replacement pump I just bought from a pool store has been leaking a tiny bit of oil from the fill plug on the pump motor. Oils like this have a fair amount of thermal expansion so the plug might be designed to leak some, and it's been the hottest part of the Summer. I'm wondering if it would be better to plug it with hot glue, rather than allow leakage, but leaving a small air bubble in the motor after refill to allow for oil expansion.
