Yes, it's legit, bio-diesel even predates petroleum by about 15 years. It is still used in farm machinery, and here in Northern California, it's slowly becoming a fad, I'm seeing lots of bio-mercedes and bio run vw passats. It burns on par with petroleum based diesel, it's not any better for the environment, but it's great for the agri-industry and bad for the oil industry.
