Does anyone know what type of oil the E66 uses? Well, actually, I know it's Castrol Syntec 5W-30, but I don't think Castrol makes that anymore . I think they call it EDGE now. I checked the back of the EDGE container, and it doesn't have any of the BMW LL specs that the 0W-30 European formula has, so I'm a little wary of using it. Suggestions?
