I have a MityVac 7201 and am pleased with it.

My driveway has a slight slope down to the street, so when using the extractor I position the front passenger side, the side with the dipstick, to be the lowest point of the car on the driveway.

My only problems have been with pumping the oil out of the extractor into milk jugs:

• Don't put warm oil into milk jugs! AMHIK.
• Remove the thinner extractor tube before pumping out the used oil into the vessels of your choice.
