Dave, it's not in violation of physics! There is no lowering of the
breakdown voltage either since the dielectric strength of the Sunsil oil is
the same as that of mineral oil which doesn't differ much from that of the
polyethylene. If one makes a sandwich out of several dielectrics with the
same strength but differing dielectric constants, the resultant capacitors
value seems to be determined more by the higher dielectric constant than by
anything else.
