How often should I change the engine oil in my BMW XM?

I recently bought a BMW XM and was wondering how often I should change the engine oil for optimal performance and longevity. Any tips or insights on this matter?

It is recommended to change the engine oil every 5,000 miles or every 6 months, whichever comes first. This ensures that the engine is running smoothly and all impurities are removed from the system.

Another good rule of thumb is to change the oil every year, even if you haven't reached the 5,000 mile mark yet. This helps maintain the engine's performance and prevents any potential damage.

It's always better to err on the side of caution and change the oil more frequently, especially if you frequently drive in stop-and-go traffic or harsh weather conditions. In these situations, it's recommended to change the oil every 3,000 miles or every 4 months.
