<< Actually Ray, plain U.S.P. mineral oil has better dielectric qualities than
any "transformer oil", cheaper too! If you can get samples then look into
the refrigerator compressor oils some like Sunsil (I think that's the name)
have double the dielecrtric constant of mineral oil puting it in the 4+
league! Roll a cap and fill with this type of oil and double the
capacitance!

Alfred,
If the primary dielectric material of the cap is polyethylene with a K of 2.0
to 2.3, using a high dielectric constant oil will not raise it. The cap will
measure the same - or very close, with either type of oil.
