Hi Luke, I get oil like this from one of my suppliers. I don't get the black sediment layer but I do get two distinct layers even after thorough dewatering. The upper layer is clear oil while the lower layer is caramel coloured and about as solid as soft butter. When it was warmed up, it would melt to a liquid and become much darker, coffee coloured. (espresso) I have separated this lower layer out and tried making a test batch with it, with reasonable results. My best results were with the acid/base process. Dewater your oil thoroughly and try a test batch, it is the best way to know for sure if it is usable or not.
