How to get better fuel efficiency in my Nissan X-Trail?

I just got a new Nissan X-Trail and I am wondering how I can improve its fuel efficiency. Any tips or advice would be greatly appreciated!

Hi John, congratulations on your new Nissan X-Trail! One of the best ways to improve fuel efficiency is by keeping your tires properly inflated. Underinflated tires can decrease fuel economy by up to 3%. Also, try to avoid aggressive driving and keep a steady speed on the highway. This will help you save on gas. Lastly, make sure to regularly maintain your vehicle by getting oil changes and tune-ups. This can greatly improve your car's overall efficiency. Hope this helps!
