Mike, very interesting.
According to your supplied INFO, BMW changed to Shell during 2015 - my car is built 2014.
I would not risk changing to oil, which might have better cleaning ability - that could release dirt in engine.
I asked - out of habit - which oil dealer used at oil change. Luckily it was Castrol - but I got no INFO about BMW changing oil from 2015.
Since next oilchange/service will not be free, I am turning to nearby ex-BMW mechanic. I will obviously make sure he uses Castrol.
