I lived in Germany for about 19 years.  Prior to 1992, I used to see
machines at the Esso, Shell and other gasoline stations where you would
insert your 5 Mark piece and insert a tube from the machine into your
dipstick tube to suction our the oil.  They were discontinued a few years
ago because (I think) they did not completely remove the oil (still some in
the filter) and were environmentally unfriendly.  Bottom line: it works, but
doesn't remove all the oil, so you will still be running on dirty oil if you
don't also change the filter at the same time.
