The neat thing with the oil dielectric is it is basically self healing ,
even if it does arc over- no permanent capacitor damage will result as long
as the power is shut off fast enough.. and that's the current issue-no pun
intended!
The un-neat thing about an oil dielectric is its propensity for catching
fire... also, I don't think it has particularly low loss at RF - although a
lot of big TX capacitors are oil-filled, the oil is there to increase the
breakdown voltage, rather than act as the main dielectric, which is usually
mica, I believe.
