Any thoughts on what oil to use at my break in oil change? The Warranty booklet (page 6) says that BMW Castrol 5W30 and Mobil1 10W40 are strongly recommended oils for the 1 series. They do not list any other oils or weights.

Of course if you read the owner's manual (page 117) it only recommends using BMW 5W30. It also says to use 5W30 or 5W40 weight as they work in all temps.

Since I live in Cali with no chance of seeing temps near freezing, I am thinking the Mobil1 10W40 is the oil to go with. But this is my first turbo engine and I not not sure who weight of oil works well in them. Any thoughts on what oil would be best out of the two "approved" oils given where I live and that the car will see some autoxing and maybe a track school or two?
