Don't mean to be semantics police, but what you are referring to is SVO, (straight vegetable oil, which is not only a fuel, but a method), and not biodiesel. Biodiesel is veg oil which has been altered through the process of transesterification, which changes its viscosity closer to that of pump diesel, thereby not necessitating the modification of the vehicle. SVO on the other hand, properly done, requires modification of the vehicle.
