I use this air pump to suck the oil out of my Mercedes W123 motors, as the dipstick tube is lower than the drain plug. I put the hose over the top of the tube and it will pull all the oil out of the motor in about 45 sec.! No more crawling under the cars for me. I will have to make a tube to fit on it, for other motors, but for the W123 cars its the best thing since sliced bread!
