How can I maximize my fuel efficiency in the BMW X7?

I've noticed that I'm not getting the advertised fuel efficiency in my BMW X7. What steps can I take to optimize my driving and get the most out of my fuel?

First, make sure you're properly inflating your tires. Under-inflated tires can decrease your fuel efficiency. Secondly, try to avoid heavy traffic and stop-and-go driving as much as possible. Maintain a constant speed and use cruise control on the highway. Lastly, check your air filter and replace it if necessary.

In addition to the previous suggestions, I would also recommend using premium fuel and keeping your vehicle's weight to a minimum. Avoid carrying unnecessary items in your car and try to limit the use of accessories that may drain the battery.
