Did the same with a half gallon jug, been using that for 40 years and thought everyone else was too.I've posted this on another thread but it fits here also.
Take a gallon jug and cut it lenth ways. Cut the bottom in a curve to hook behind the filter. Loosen the filter enough to be able to spin it by hand then insert your modified jug. Keeps the oil from going all over the K frame.
