- thanks for your good wishes, so far Ive had really good results with four consecutive litre batches of new canola oil using the usual 200 ml methanol and 3.5 grams of lye, agitating it for fifteen minutes with great results, a brandy coloured layer of glycerin and a layer of soap with the rest being fairly clear biodiesel, but yesterday afternoon I used wesson brand soybean oil (new) and found a clear layer at the bottom about 1/4 inch deep and the rest of the oil is cloudy it just doesnt seem to be a complete reaction. can you tell me why the canola worked and the soy didnt seem to?
