The full title of the book wasnt "High performance Diesel Builders Guide and other book titles that dont make sense" was it? If you were serious I guess no mercedes engineer read the book, at least not before they made my 300D. 1-100 k/hr times you just about need the minute hand on the watch to measure.......

I think rudolf designed the engine to run on straight veggie oil, not bio, but the thinking is right.

I also think that to run a car on ethanol it may require some tweaking of the cars injection system, as it requires more ethanol to burn with the same amount of air compared to petrol. Some fuel injection systems are probably fine, perhaps others not.

Of course biodiesel plants are probably easier to keep from exploding than ethanol stills. Not saying of course it cant be done, but biodiesel (as I understand) is generally made at cooler temperatures than ethanol.
