Biodiesel is a renewable fuel made from vegetable oil. Sure, it smells like french fries or chicken fried rice when you drive on it, but is it safe to use? Do I have to convert my car to use it (and if so, how?) If it’s so great how come everyone isn’t using it? Does it take more energy to create it than you get out of it? Won’t we have to give up food production to make it? Will it void my car warranty? Find out the surprising, astounding and amazing answers to these and a dozen (or so) of the most common questions about biodiesel.
