Question

How do you know if a batch of biodiesel is good?

Answer 1

it is called the 3/27 test start with a container of 27 millileters ethanol or prefferably methanol... then add 3 millileters of biodiesel if it dissolves easily you have good fuel ... also watch the color it should be clear if not you probably have water left from washing just put it in a warm place with no lid and the water will evaporate... I strongly suggest washing your biodiesel 5 times before allowing to dry then dissolving a sample before using
