I was disappointed when they put the wrong type of oil (5W-30) on my 2004 BMW M3. Josh insisted that it was the right oil for the region. I took my car to Bellevue BMW and was informed of low oil pressure. Had to get my oil change again. BMW strictly recommends Castrol TWS 10W-60 for //M cars. This information was printed in owners manual and a sticker in the engine compartment.
