I was told that the first ever diesel engine was designed to run on peanut oil. I've never seen a citation though, is this correct?

I was also taught that using a 20% biodiesel 80% fossil fuel derived diesel mix had been found to improve engine life, due to the improved lubricating quality of the mixed fuel. Does anyone know of any good quatily citations either way on this? (as there seems to be alot of people jumping on the band wagon making unproven claims both for and against biodiesel)

It would be interesting to know if they've had to modify the petrol to ensure that the biofuel is compatable with a petrol engine. I didn't know that they could produce biofuels that ran in petrol engines, though I guess that maybe they use cracking or something to produce shorted hydrocarbon chains that are compatable with the petrol engine. It would be great to know the processing that is used.
