How do I properly maintain my BMW X5 for long-term use?

I just bought a used BMW X5 and I want to make sure I take care of it to keep it running smoothly for as long as possible. What kind of maintenance should I be doing and how often?

Regularly check and replace the oil, filters, and spark plugs. Also, make sure you follow the recommended service schedule for your specific model and year of BMW X5.

Keep an eye on your tires and make sure they are properly inflated. This will not only improve your fuel efficiency, but also extend the life of your tires.
