You will need the following parts and supplies to perform this repair.

BMW TwinPower Turbo Engine Oil

The debate over which brand of oil is best for your BMW is worse than politics these days. All we can say is in our opinion, the best engine oil is factory engine oil. Genuine BMW TwinPower oil is the same engine lubricant that your BMW was shipped from the factory with.
