How to make your own biodiesel
There are at least three ways to run a diesel engine on biofuel using vegetable oils, animal fats or both. All three are used with both fresh and used oils.
* Use the oil just as it is — usually called SVO fuel (straight vegetable oil) or PPO fuel (pure plant oil);
* Mix it with kerosene (paraffin) or petroleum diesel fuel, or with biodiesel, or blend it with a solvent, or with gasoline;
* Convert it to biodiesel.
The first two methods sound easiest, but, as so often in life, it’s not quite that simple.
