What is the most efficient way to increase gas mileage in my Nissan X-Trail?

I've been noticing that I'm spending a lot on gas for my Nissan X-Trail and was wondering if there are any tips or tricks to improve its gas mileage. Any advice would be greatly appreciated!

One thing you can do is make sure your tires are properly inflated and aligned. This can greatly improve your gas mileage.

Another tip is to avoid aggressive driving and excessive speeding. This can use up a lot of gas and decrease your mileage.
