M3 2008 Engine Oil

Is anyone with a new M3 using anything other than Castrol Oil??? I've spoke with several dealers and even called the Toll Free Service Number and everyoe told me that Mobil One 15W 50 would be just fine. I've been a Mobil One user for some 25 years, I'm just not a big Castrol Fan after all of these years with Mobil. Anyone else using Mobil One?????????

From my owners manual, its says that the oil in the engine, transmission and differential are changed at the post break in-1200 mile service. It didn't mention the oil filter so I don't know if that is changed or not.

After looking at various procedure and data pages I was able to come up the the capacities and types of lubricants that are required for the 1200 service. It might be wise to confirm that your dealership is using the correct lubricant for each of the three applications. Sometimes shops use only one grear lubricant for all applications. But a specific and different oil is necessary for the transmission and differential.
