Just out of warranty and went to a reputable european auto shop for my most recent oil change. They recommended 5W30 oil but my dealer has always put in OW20.

Did some research and found this from FCPEuro: “New BMW's fitted with BXX series engines (B58, B48, etc) "require" 0W-20 LL14FE+ Rated oils. WE DO NOT RECOMMEND using this spec! The levels of protection LL14FE provides are much lower than bmw’s previous standard LL01. The new formulation LL14FE is mainly designed with CAFE ratings, EPA requirements and fuel mileage in mind, NOT OVERALL PROTECTION. We recommend LL01 rated oils for increased engine protection and shear resistance.”

I live in Michigan where temps range from probably -5 - 90 degrees. A bit of a spirited driver. Which oil should I use? Will there be any damage from running 5W30?
