It's not mind boggling at all, a motor works more efficiently when it has to work less to push the oil around...provided the oil does not allow metal to metal contact.

So let me get this straight: you're going to take the word of Dr. AE Haas, a Florida plastic surgeon, over that of BMW engineers regarding what oil to use in your Bimmer.
Dr. Haas writes up a long convoluted treatise on oil http://www.bobistheoilguy.com/aehaas/index.html ,a subject his medical training has well prepared him to expound on, and all of a sudden he's an expert on oil.
Give me a big time break
