Castrol R.
In the late '70s I was told that it still could hold its own over mineral oils
and
this held true until the advent of synthetic oils

Castrol still do make a Castor Oil based lubricant - Castrol R40. The product
description says:
"Castrol R40 provides the ultimate in lubrication. If the best possible
performance coupled with
reliability is the aim then the remarkable stamina and great film strength of
Castrol R40 will provide
a valuable margin of safety at ultra high engine speeds and temperatures. A
castor based lubricant which is primarily designed for the racing world;
however its unique
properties can also benefit private owners interested in high performance.Never
mix Castrol R40 with mineral based or synthetic crankcase oils"
That'll give anyone a "run" for their money!
