i need to know how to make my truck run on bio or anything that isnt 3.29 a gallon.

I'd suggest looking here. (http://biodiesel.infopop.cc)

I converted to WVO a year ago, 23k miles on it now. Check out; http://www.frybrid.com/test.htm you will be surprised at what you can do. There is a great forum there about running WVO.
