Nice article, I can think of more than a few people around here that could benefit from reading it. There are a few stations in my area that sell B99 and a lot of people with diesels use B99 exclusively, though I really doubt that they have changed their maintenance and/or lubrication habits to cope with the change to biodiesel.
