Did my first oil changes with the Mityvac 7201 on our GTI and Q7. It pretty much works as advertised-it DOES suck (heh). I have a couple of tips:1: I sucked up 1 liter portions of water and then marked the location of each liter gradation on the side of the reservoir so I can see more precisely how much I'm pumping out.2: This thing will also reverse and pump out fluids. The only thing that holds the "extension" tubes to the main connection tube is a friction rubber fitting. It holds fine in suction mode. In pump out mode, which I thought to use to move the used oil to the empty containers, it pushed the thinner tube that goes down the dipstick hole out of the rubber fitting in a remarkable imitation of the water fountain show at Vegas's Bellagio hotel...only with toasty warm used motor oil.
