Response to Biz4two:
I know there are many oil debates and I do not want to turn this tread into one of those...
These are just my thoughts:
1. I use M1 on my other vehicles ...2 Porsches and 1 Mercedes
2. I've used M1 successfully on my 2006 Audi A4 2.0T until I sold it with 167,000mi
3. That being said I recognize the lack of the BMW LL-01 rating for M1
4. Part of me thinks this is just marketing and back door deals that I can prove by testing it in my engine for 2 cycles and reviewing the reports
5. I am considering the Castrol Syntec 0-40 Euro blend as a test as well
In any case I think the most important thing to do is ...just change the oil
