Original poster: "Marry Krutsch by way of Terry Fritz <twftesla-at-qwest-dot-net>" <u236-at-earthlink-dot-net> Hi All. What is the breakdown voltage of kerosene and motor oil? I want to try to make a cap that uses only motor oil or kerosene as the dielectric. I know I want additive free oil, but will I need to dry it before use? Can someone who's done this give me some pointers? Thanks, Winston
