Well, the Fendts are fitted with Deutz engines, which have been designed to run on bio-diesel since 1995, but it looks like all the others are lagging behind. I was really hoping for something that would run on pure canola oil, rather than processed bio-fuel. Any experience with that? Apparently the problem is with common-rail electonic injection systems, does anyone still make basic mechanical ones?
Ah well, until something shows up I'll try to find out if I can put a Deutz diesel into a pickup truck. 
Strategery of co-opetition will embiggen a cromulent future.
