What is the difference between biodiesel and VO?
We think of biodiesel as a transition fuel. You can use it just like petro-diesel, putting it directly into your diesel fuel tank. Biodiesel is vegetable oil that has been chemically altered so that its molecular structure mimics that of diesel fuel. It can be used straight (B100) or mixed with diesel in various ratios (B20, B40, etc.). Vegetable Oil, on the other hand, is not chemically treated. It is just filtered vegetable oil. It requires specific conditions (namely, controlled temperature) in order to burn efficiently and not create problems with the vehicles fuel system. Here is where the conversion kit comes in. Most conversion kits allow you to keep your diesel and VO separate, and to switch back and forth between them.
