I have installed Fumotos on Ford 7.3L diesel trucks [2], very valuable there because of the frequency of changes [with dino oil, usually Rotella] and volume [nearly 16 qts] of oil. This is why I asked whether the drain plug on our 3.0L M54s is inset [and on the side?], if inset, I'll need the adapter. I can't remember what it was on my E36 6, where I never installed a Fumoto. Its a well made and very handy device if you change your own.
