It requires a special Castrol full synthetic 10W-60 oil designed specifically for that engine. You aren't going to find it at the local Jiffy Lube. The engine also requires valve adjustments every 30k miles. From what I have read on owners forums that service costs $2,500 or more. If I were to buy one it would be maintained by me only.

The only reason they say Castrol is "required" is because Castrol did something for BMW that will never be disclosed. And 10W-60? That's going to result in a lot of deposit-causing additives being used in the formula, because additives are the only way they can achieve such a big spread between the 10W and the 60.
