making bio-diesel isnt a risk atall there really isnt any problem with it, i saw an epsoide of trucks and kelly made bio diesel with a kit you can by , and he didnt even use store bought oil he used old oil from a mcdonalds or something along that line, and it really isnt hard or dangerous, dont get me wrong things can still happen but thats true with anything you do , a llittle risk for gas thats 70$ a gallon or pay 3.20 at the pump , you choose
