I'm sure it will work if you found the right bolt size.. but don't forget.. your "regular car" eats 10w30 which costs maybe $6 in engine oil, your ml eats 15W40 synthetic which costs $80 so can you afford a drop? if it fails (all the oil drop out) can you afford no engine oil in you ml for a short period of time? plus there is a annoying bar directly under the drain plug, so engine oil will fly everywhere! you can always put a piece of cardboard thats what i do... I wouldn't recommend it...
