I had never heard of pumping your oil out through the dipstick tube
until a few months ago when I joined a Mercedes diesel list.  Apparently
this is very popular among Mercedes DIY folks.  The only real advantage
cited was the ability to keep from having to crawl under the car and get
dirty.

I don't quite understand that as the MB diesel drain plug was
conveniently located just about where any plug would be.  It was an easy
job using the usual method - with a drain pan, etc.

Those diesel engines do get very frequent oil changes, but, as Dennis
mentioned, it seems like crud could easily build up in the bottom where
some will be left behind every time.
