I was searching the net for bio-diesel and found Diesel Secret Energy. They say that you can produce it for .46 cents a gallon. No convertion needed to run this fuel. Has anyone used or heard of anyone using this. Almost sounds to good to be true. Check out www.dieselsecretenergy.com. Sorry I dont know how to set up links so gotta do it the hard way. Diesel just went to $2.44 gallon here so I am really considering this, what do the rest of you think??
