I have been using it in 5W-30 on my other BMWs for DIY oil changes since I read the article in Bava's Fast Times newsletter (http://www.bavauto.com/newsletter/20...ter.pdf#page=1
). Will use the 10W60 for DIY changes in my E92 M3 -- there's already some waiting in my garage.
Not sure what to think about BMW brand recommendations. First they're telling me to only use Top Tier gasoline dealers in the U.S. Then they tell me they recommend BP (not Top Tier). There seems to be some play in the joints with this stuff.
To each his own.
