I also do not recomend any product with silicon in it for the same reason. As Miriam said I use clock oil which is a synthitic sperm whale oil as the manufactures of this vintage machine recomends. It is a light oil that will evaporate slowly. We oil clocks one a year with this oil and they run all year with no problem. If you do not want to buy clock oil which is not cheap only use sewing machine oil that is of good quality.
