Bean oil is derived from pressing oil out of castor beans and distilling it. It is an excellent lubricant. It tends to seek out hot spots in the engine and clings to those hot surfaces much better than petroleum type oils. Bean oil, however, does not mix with gasoline easily and it burns dirty producing excessive carbon or varnish deposits.
In the early 70s, before power valves were used, castor bean oil was very popular in racing 2-strokes.
