Guess what, we are already seeing what happens, people are putting hundreds of thousands of miles on biodiesel (mostly truckers who have been using B20 for many years). Biodiesel is not as new as you think.
Stability is a concern, but there are ways around it. There is argument in the field about the necessity to leave tocopherol (vitamin E) in the feedstock during processing, which causes it to remain in the final biodiesel, or to remove it for sale by itself. Tocopherol should be left in, or even ADDED to biodiesel, because it prevents oxidation, and increases thermal stability. I agree that there should be an ASTM standard for thermal stability, but I'm confident that biodiesel producers can meet that standard.
