Learn to Make Your Own Biodiesel - Part 2

The last processing step before the biodiesel can be added to the vehicle's fuel tank is the final filtering. We like to use commercial grade restaurant filtering bags in the 5-10 micron range. This ensures that we capture virtually all debris before pouring the biodiesel into the car. Keeping this dirt out of the tank obviously lessens the load on your fuel tank strainer and built-in fuel system filters. Some biodiesel recipes recommend washing the biodiesel before putting it in the tank. We don't wash our fuel and have driven in excess of 75,000 trouble-free miles in our indirect injection, non-computer controlled diesel Mercedes Benzes. If you are driving a more modern diesel vehicle, we do recommend you wash the fuel.
