Check out the oil BMW recommends on the M3 maintenace page of the BMW North American web site. Guess the IT guys haven't gotten the word yet about the 10w60.
M3 oil recommendation
![[Roll Eyes]](images/icons/rolleyes.gif)
quote:The screwup was with BMW North America. The engines came from the factory with Castrol 10w60 in them. The service departments here put in the 5w30 when they would change the oil, based on this oil being specified across the board for US BMWs. I suspect that BMW in Germany thought this would be okay because they assumed that US driving styles and conditions are not as demanding as those in Germany. Obviously, when it comes to the M3, they were wrong, and the 5w30 couldn't cut it.
Originally posted by Patman: I always found it odd that BMW originally specified these engines to run 5w30, then all of a sudden said oops, now we need to use 10w60 in here. That's a huge difference, and makes me wonder exactly how much testing do they do with these engines to determine their oil recommendations? Obviously not much.

quote:I am confused on this. It seems that the 10W-60 recommendation was tried and failed to fix the spun bearing problem. It was later determined that a production fault was the real cause. Certain bearing clearances were adjusted. Is 10W-60 the current recommendation for the S54 engines, due to increased bearing clearances? Is this still in effect for the most recent cars?
