Shocking to me, and my 911 uses about 1/10 of that, but I wonder what the spec is for the X5.

My 2001 X5 has the standard automatic rust inhibition feature where it leaks a carefully controlled amount of oil, eventually captured by the stiffening plate for recycling, keeping the entire lower engine coated in a 25 micron protective film of oil at all times.

dude check that up immediately, that in my opinion IS a HUUUUGE PROBLEM, because of that your engine might get hydrolocked and then say goodbye to it (i mean that's what i've heard)
