Break in oil
It is my understanding that synthetic oil is insuffecient (too slick) to proberly seal the rings for break in. I will acquire my 330i at the end of the month, and intend to immediately replace the synthetic oil with dino oil to facilitate proper break in. To me, this seems like a no-brainer, and I am surprised that this has not been brought up before. Am I missing something? Please advise.
