Hello all. I am interested in making my own biodiesel and have been reading up on how the process works. Recently I ran across the chance to pick up a few hundred gallons of old oil. I was told that it was rancid. Im not sure what that means and how that would affect using a rancid oil to make biodiesel. Anyone with knowledge about this? Thanks in advance.

 

I geuss you would have to elaborate on Rancid. IT could mean high titration, very puke smelling, Or milky watery oil.
