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!
