I did a search and my results weren't all that clear as to the answer I was lookin for so...


Can I run 100% biodiesel in my 01 7.3 or do I have to mix it? In what ratio should I mix it?



next question... anybody used this http://www.dieselsecret.com ? I figure it wouldn't hurt to try it, but it sounds a little risky. Anythoughts? any help is appreciated
