Your going to be hard put to find a gas dielectric with any sizable
dielectric strength with out resorting to high pressures, air for example
increases it's dielectric strength from 30 - 70 volts per mill at one
atmosphere to 500 volts per mill but it takes 20 atmospheres of pressure!.
I wouldn't suggest the 10W30 automobile oil there is far too many additives
in it! Your best bet would be U.S.P. mineral oil with it's dielectric
constant of 2.2 to 2.7 and it's dielectric strength of 200 volts per mill,
or better still one of the high dielectric constant refrigerator compressor
oils like Sunsil. It's dielectric constant is 4 and it's dielectric
strength is the same as mineral oil!
