oil drain "valve" fumotovalve ?

[rp41]

West Marine: Oil Change Unit Product Display take a look at this one it's what I use, 13 quarts and the tube goes down the dip stick all the way to the bottom of the pan.

I used MityVac and used the rubber connector to attach the main tubing directly to the dipstick tube.
After sucking all oil this way I attached smaller tubing, that went inside the dipstick tube all the way to the bottom of the pan. No more oil come out this way, so dipstick tube on this engine is design to suck the pan dry.

Same here, with the nipple & hose, simply no better or easier way. Engine Oil Drain Valve

OK lets race I say there is no easier way than sticking a tube down the dip stick and sucking it out. By the time the oil is out of mine I have the filter changed and ready to pour in the new oil. I can't believe crawling under yours with a pan and the mess is easier

Wrong logic.
It only means that the smaller tubing goes only as deep as the bigger tubing.
You need to open the drain screw at the bottom of the pan to prove that all oil is sucked out.
I don't bother with that. I just add an additional quart of new oil to flush out any remaining old oil.

No, because the dip stick tube doesn't go to the bottom of the pan. It's shorter but the small tube does

Do these pumps drip either. As you remove it from the dipstick tube, or when they are stored in your garage from the residual oil ?

Have used Mityvac on ml320 and 560sel. No muss,no fuss.

And how do you know that (the small tube is at the bottom)?
The tube clearly hits something, but it doesn't necessary mean the bottom (lowest point) of the pan.
I use exclusively the small tube, and everytime, I throw in an extra quart of new oi to flush out any left overs. Invariably, the oil that comes out is still dark (although not as dark as in the begining of the process).

I got the pump, its the greatest. I even used it on my differential fluid change and transfer case too. You can even use it to deliver fluid to the differentials also. This is what they use in deutschland I believe.
