I suspect that any DRY oil should be OK. However, all of the
transformer oil I've seen has an additional desireable property - low
viscosity which makes it easier to get all of the bubbles out. I
suspect Kerosene might even work, again if it's dry. The oil in the
oil-filled filter capacitors I have have is different, with much higher
viscosity. About like castor oil and may actually be that in some of
them. It would be a horrid job to pump all of the air out of something
impregnated with that stuff.
