How can I optimize the fuel economy of my BMW X3?

I've noticed that my BMW X3 is using more fuel than I expected. Are there any tips or tricks I can use to improve its fuel economy?

First and foremost, make sure your tires are properly inflated. Under-inflated tires can greatly decrease your fuel efficiency. Also, try to avoid hard accelerations and sudden braking, as these can also increase fuel consumption.

Another way to improve fuel economy is to regularly maintain your vehicle, such as getting regular oil changes and replacing air filters. This can help keep your engine running smoothly and efficiently.
