Why is the engine oil in my BMW 6 Series getting dirty so quickly?

I've noticed that my BMW 6 Series seems to be going through engine oil much faster than usual. After just a few thousand miles, the oil turns dark and dirty. Is this a common problem and what can I do to prevent it?

Dirty engine oil can be caused by a number of factors, such as short distance driving, stop-and-go traffic, and frequent idling. These conditions don't allow the engine to reach optimal operating temperature, causing the oil to break down more quickly. Consider taking your BMW 6 Series for longer drives or using a higher quality synthetic oil.

Another possible cause of dirty engine oil is a faulty PCV (Positive Crankcase Ventilation) valve. This is responsible for removing excess moisture from the engine, which can cause oil to become dirty. Have a mechanic check and replace the PCV valve if necessary.

Regular oil changes are essential in maintaining the cleanliness of your BMW 6 Series's engine oil. Follow the recommended schedule in your owner's manual and use the manufacturer's recommended oil for best results.
