There's a filter that needs to be changed
......
Thanks for the comments and I did get a laugh about sucking out the filter
. Even with access to a good floor jack and jack stands, this seems to such a clean easy way to change oil. I had a brain fart the other day changing the oil on my rover (nice easy remote filter on top) and spilled about a quart on the floor which made me think about this again. And while I'm not a Mercedes fan - I understand that this is how they change the oil on all of their vehicles.
As far as harbor freight I do have a love/hate feeling about the cheap chinese tools. Much of their stuff is junk, but for cheap (the definitive word) tools that you only need to use on rare occasions - they are ok. I will never buy the cheap plastic zip ties from them as they ALWAYS break right when you don't want them to.
