Not sure, biodiesel from soybeans has good lubricity, and works really well. It’s not cost effective though.
Both Hitler's and Tojo's war machines basically ran the last six months of the war on biodeisel, wood alcohol or whatever else they could find. What little petroleum was available was reserved only for high-end applications like aviation.
An acquaintance of mine with more money than sense told me that, rather than replacing a failed oil pump in his Honda Accord, he just decided to dump an occasional quart of whatever lubricant he had into the crankcase (used motor oil, fat, grease, whatever) just to see how long the engine would last. He drove it for more than a month before one day, the engine just seized up and died.
