Where can I get mineral oil to do this?

oil is not electric conductor. water only conduct electric
(electric cannot go through)
if you really want to use mineral oil ..... get baby oil (it's mineral oil) or other extra (double) purified mineral oil for better efficiency

baby oil is purchasable in supermarket, pharmacy, or kedai runcit
avoid fragrance ones, coz those are addictives

you could also use silicone gel (lubricant), which purchasable in supermarkets, autoshops, hardware shops. keep in mind, silicone gel is not a good heat conductor, compared to the mineral oil

besure to keep in mind to get a a good pump which can deal with high vicosity fluids ... if you want to keep the oil cooled
