One thing I've found when the tube is inserted in the dipstick hole, it is possible for the tube suck itself against the bottom of the oil pan reducing extraction to a trickle. I use a little hand pump and can feel it grab and the pump is hard to work. Lift the tube half an inch and all is well. I think a lot of people experience this problem without realizing it. Also, the tube comes coiled. When inserted, it can curl up above the oil level and suck air.
