All vegetable oils do that. Copper catalyses rapid oxidisation and polymerisation. See "Copper and SVO": http://journeytoforever.org/biodiesel_svo.html#copperstudy Castor oil has a lower iodine value than either rapeseed oil or soy (much higher), and is thus more stable - it wouldn't have happened without the copper. Castor oil has excellent lubricity and is a good candidate for biofuel, either biodiesel or SVO. Say "Castrol" slowly. That's what it started off as. Previous messages: "Castrol R or Mobil P, both castor based oils are still the prefered lubricants in the worm/wheel diffs as fitted to Peugeot 203,403,404." "Castrol are still selling castor oil for 2-strokes, especially for racing."
