Credit then, goes to both of you. I wonder if castor has been used for so long and just did the job that olive was simply overlooked as not just an alternative but an oil with specific, beneficial properties.

I have Biodiesel made from a selection of oils including coconut and olive. Maybe I'll try to make some from castor. Would that give you a biodiesel fuel that requires no additional lube?? Or, a BioLube that not only lubes at 20% but burns contributing to low emissions and extra power in a standard, diesel mix?
