You just need to think what the diesel engine was originally designed for

Yeh Peanut oil wasen't it?
Then it was coal dust and Rudolf the Red Nosed Diesel engine inventor almost killed hismelf after the coal dust experiment caused the engine to explode
Someone told me if you get a clear bottle mix bit of biodiesel with water and leave it overnight. If the next day the biodiesel is clear it's good and if it's cloudy it's not. Haven't have the chance to try it yet though
