I have used this about 5 times so far.  The only problem I had with it is that it would not go down the check tube of my mercury mountaineer far enough to extract the oil.  It works great on both of the ford taurus' tho.  I haven't tried it on anything else.  But it has paid for itself almost twice after 5 oil changes.  This is really worth it.

You put the extract tube in the car and pump it up.  Go off and do something else for a while.  Come back pump it up again.  You will see the oil flow again and go away again for a while.  Do this maybe 3 times and your done.

It does help if the car is a "little" warm, but it will work if it is stone cold, just might have to do the process a few more times.

Once your done, just pop off the top and put in a container and take to AutoZone and recycle....  I would buy this again with out blinking a eye.
