Again this is not about oil vs dry, google the subject if you feel like wasting couple hours.
Its about the argument you used. You said BMW do not come with oiled filters so dry must be better than oiled.
And im saying, thats not necessarily the case, dry filters are cheaper and require no maintenance (which means no free warranty work by BMW which means less cost and more profit).
