Just my 2 cents worth, but I've been making biodiesel for about 18 months now, and post on 6 different biodiesel forums. The best and most reliable site I've ever found is http://www.biodieselcommunity.org/onlineresources/ This is a compilation of many sites from around the world, and is THE site to start from. There is a world of experance and many people willing to share there stories. Lot's of help for nube's. I see you are near my location[ arlington or ] If there is any help I can offer just let me know.FABMANDELUX.
