Lots of people use biodiesel to describe using straight vegetable oil as fuel. That requires modification to the vehicle because of oil's higher viscosity than diesel.
Biodiesel fuel can be used in regular diesel-powered vehicles. It is vegetable oil that has been processed. I'm aware of a realtor (not one of the Johns) on the Big Island who runs his unmodified Jetta on biodiesel that is converted by a friend of his.
