BMW has reduced it's service interval from 30,000 KM to around 12,000 KMin 2014 cars. However one should be smart and if you have a 2012 or 2013 car, please read on.
I have heard of cases of oil sludge in BMW engines where the service interval was not respected and some people drove beyond 30,000 KM
But really, one needs to be aware of the different kinds of synthetic Oil
The long story cut short is the Synthetic oil sold in Germany, like GC - German Castrol, and European formula Mobil 1 is made of group 4 oils, which includes PAO, which is a man made chemical.
However in the USA, group 3 oils, which are really high refined mineral oils which have been hydrocracked and very high quality, are also called Synthetic oils.
It's now become very difficult to know how much of the Synthetic oil you buy has of group 4 vs group 3 base oil.
And because of this, I would reduce my service intervals, and it seems the BMW new oil change interval of 12,000 KM is about right.
Personally, because I love my car and want it to last, I might even change the oil earlier.
I think it would be useful to compile a list of oils, what they cost and where to change them, in this new light.
