If you use Castor stay away from the medical grade that you get at the pharmacy. Most hobby shops who deal in model airplanes sell Castor oil that is refined differently and meant to combine with a fuel base, so no sludge. From your avatar you should be familiar with the Sig brand name. They make a fuel grade Castor blend. The medical grade will work but it can produce deposits that will eventually foul a plug...or worse, if used to excess.
