i did see Mission Performance recommended replacing the spark plugs which i am going to do thru them when i tune it with them. I have had any issues with oil but thats probably bc my commute is very short and i havent really pushed it too much yet.

Edycol in this forum link below seemed very knowledgeable about what oil to use for our B58. Nevertheless, I am concerned that Castrol 0w-40 (which is no longer a LL-01 rated oil) will somehow cause issues. Since BMW doesn't share what is in the oil, it is hard to say how good it is. I ordered 7 liters of BMW 0w-30 LL-01FE from ECS tuning for my next change.
I think it will be best to ask MP for recommendations.
