BMW's confusing and self-contradictory statements regarding oil for M motors comes down to two things;
1 - A way to wriggle out of repairs under warranty, chances are the car did not follow the reccomendations every time they were changed,
and
2 - The prevalence of the internet means that you guys in the US can pick up a TSB that was meant for the colds of Northern Europe (or some other geographical crossed lines leading to misinterpretation)
Bottom line?
Redline or Millers.
