I see this statement frequently, and I do not belive it to be true. On my '97 E 300 D, I use a small plastic tube inside the dip stick tube, and if I push past where it hits the bottom of the pan,the tube will curl up in the crankcase and I can easily push in all the tube I have. It will actually get up to where it sucks air from above the oil level. This could not happen if the dip stick tube went nearly all the way to the pan. I have not sucked from the top of the dipstick tube and then removed the drain plug to see how much oil remains because my drain plug is in so firmly I suspect the threads are compromised. On this car, if I loosen the oil filter cap the filter will drain into the pan with no sucking involved. I am quite happy with the Topsider using the plastic tube inside the dip stick tube, although it does take awhile to suck it all out. Maybe 15 minutes with warm oil.
