It's illegal to use home heating fuel No.2, nautical fuel, etc in a diesel car or gasoline purchased for farm use in a gas car for fuel tax reason, so why would bio-diesel be legal?
There's a guy in this paper who makes bio-diesel out of used vegetable oil obtained from a restaurant and turn it into bio-diesel at home to use in his motor vehicle registered to use on public roads.
