I'm a confirmed extractor. (I almost wrote sucker!) I used to do the classic drain method, and it worked fine on any car which was high enough off the ground for me to get to the drain plug and filter.
But then, while changing oil on my late beloved MB 420SEL, the plastic drain pan -- you know the kind, a 10-qt. pan with a screw-on cap and a closing lid, so you can take the whole thing to recycling -- the pan, as I say, began to *leak*. Not a small leak, a steady nasty flow. Sure, I could have brought it back to AutoZone for a refund . . . but I would have had to empty it first! Good thing it started to leak *before* I put it in my trunk!
I finished the change, disposed of the oil (never mind how), and bought a Topsider the next day. When I'm done with a change, I seal up the big metal can and bring it to AZ for recycling. In between changes, it sits -- clean -- in its box in the closet. And it can be used to suck out other fluids, too!
