^ In extremis too little oil and your engine will overheat and seize. Too much oil and you'll get a "hydraulic lock" where the pistons can't go up and down.
A less extreme too much oil can result in the pistons going up and down over-pressurizing the crankcase, pushing the oil out at the weakest spot. This should not be confused with a good old fashioned oil leak, of course.
Those dipstick level marks are there for a reason folks!
(And note to MB - there's nothing as simple and effective as a dipstick - please put them back on your engines and transmissions :-) )
