Same is in Europe. Castrol 0W40 is approved by BMW. Use it! Mobil1 5W30 ESP is approved by BMW (arguably, next to Castrol 0W30 LL-04, best oil that carries LL-04 approval.
I forgot you guys have access to Castrol 0W30 LL-04. That is next to 10W60 only oil right now in Castrol line up in Germany that is PAO based.
As long as oil is approved, use it.
What is OCI for N55 in Germany? I think your dealer is scaring you, but if he saw sludge in engines it is due to long OCI.
It depends on how you drive the car, initially is 30000km, but the CBS can calculate a bigger OCI or a smaller OCI according to how you drive.
A car which is driven only in city and does a lot of short travels or if you drive a lot on the autobahn at high speed the Idrive tell you to change every 20000km, or if you drive a lot on the autobahn but not at high speed the idirve can tell you to change the oil after 35000 or 40000km.
Personally I change the oil every 10000km (I do an oil change my self in my house with my oil but I buy an OEM BMW oil filter) without reset the OCI indicator, and when I reach the OCI indicated by the idrive I go to the dealer to change the oil without tell him that I already changed the oil betwenn two oil changes (that keeps the warranty available, and that gives me a clean car history for the futur)
When I bought my car, it was filled with Castrol Profesionnal BMW LL04 5w30, then the two others oil changes has been done "normally" with BMW original TwinPower Turbo 5w30 LL04.
I am interested in a point, the oil you buy at the dealer is the OEM BMW (Shell) but the oil used by the service shop when you go for an oil service, is it really the OEM BMW (Shell) or they use another brand (Lot of people say that every dealer has partnership with this or that brand...
What do you think about that ?
Thanks
10,000km OCI is what I would do too.
Again, if oil is approved by BMW, BMW MUST honor warranty.
In Germany in fall, winter and spring (probably in Summer too) I would use Castrol 0W30 LL-04. However, if you going often to marocco etc. yeah maybe 0W40 makes sense. I would use Castrol 0W40. That is it. Or if it makes you feel better use BMW TPT 0W30 LL-04 in Fall, Winter and Spring, and BMW TPT M 0W40 in Summer.
