How important is it to regularly change the engine oil in a BMW X3?

I am planning on purchasing a used BMW X3 and was wondering how often the engine oil should be changed and what the consequences are if I don't do it regularly.

Regularly changing the engine oil in your BMW X3 is crucial for maintaining the performance and longevity of your vehicle. Not changing it on time can lead to engine damage and costly repairs.

I would recommend changing the engine oil in your BMW X3 every 7,500 miles or every 12 months, whichever comes first. This will ensure that your engine stays in top condition and avoids any potential issues.
