Here is my take on this...
The engineering team that designed the engine specified a particular oil for a reason. There is no monetary incentive for them to spec synthetic over Dino oils or 5:20 over 15:40.
If a oil change guy thinks he knows something about the engine and oils that the BMW engineers didn't and told his customer to use a different oil, this is partly on him. The customer is also partially to blame for allowing the oil change guy to use the wrong product.
