How can I improve my Nissan X-Trail's fuel efficiency?

I've noticed that my Nissan X-Trail's fuel consumption has been quite high. Are there any tips or tricks I can use to improve its fuel efficiency?

You can try keeping your tires properly inflated to help improve fuel efficiency. Also, make sure to regularly change your air filter and consistently use the recommended grade of motor oil.

Another way to improve fuel efficiency is by avoiding aggressive driving. This means avoiding hard accelerations and braking, as well as maintaining a steady speed on the highway.
