I spoke to a service person at Allison BMW about getting my oil changed early. He stated that the oil used is a special synthetic BMW oil designed for long life. Supposedly it is different that your standard synthetics such as Mobil 1 since it is made for "long life". He also mentioned something about the particles don't set at the bottom which is why you can wait until the 15K mile oil change.
This sounds like a bunch of BS. Anyone have thoughts or knowledge in this area?
