"got my suction pump that i use on my boat and sucked the oil out thru
the dip stick tube."

When I had my Mercedes diesel for the last year or so (before it got
totaled), I learned that this is a very common practice among MB
owners.  There are special devices that are sold specifically for this.
It seemed like more people used these than drained the oil via the drain
plug.   I did it twice but used the plug and a drain pan like I always
have done.

But it is useful to remember that this can be done in case a bolt ever
strips and can't be removed when an oil change is needed.
