Anyways, I have a contact checking with the horses mouth in Munich to find the real deal. I'm trying to get get it in writing so when the dealership wants to put 10w60 in the engine, I can ask them why.

also, 10W60 is about twice more expensive than 5W30. It turned out that I have been getting 5W30 for my regular engine oil change based on my service record and I hadn't paid attention to it at all before. When I had to buy my own to top it off, I got two different answers and realized that this has been a kind of hot topic here.
