Well I ran B20 in my common rail and I had no problems. I really could not tell the difference between running bio vs. dino diesel. I am currently in the same boat getting stuff together to make my own biodiesel. If you are serious about running it picking up an extra fuel filter, like the remote kit from vulcan diesel would not be a bad idea.
