I have heard of using motor oil.  I would imagine it's dielectric constant is 
similar to trannie oil or mineral oil.  I also heard you should use motor oil 
without additives that might be conductive - like detergents.   I don't know 
how you'd determine what has been added to the oil.   I think you'd be better 
off using mineral or tranformer oil just to be sure.  Making a homebrew cap 
can be a bit of work and it would be a shame if all that work was wasted due 
to using the wrong oil.
My two cents,
