I've got castrol edge 5w40 in it at the moment. I keep hearing good things about Rotella and the local BMW specialist here uses lubro-moly 5w40 and sings its praises.

I'm looking to do a few short interval oil changes to clean the engine out. She's got a lot of miles on her, and I want to make sure I get some mileage out of her before I trade up for a 4.4 or 4.6 in a year or two.
