What is the best way to increase the fuel efficiency of my Nissan X-Trail?

I recently purchased a Nissan X-Trail and have noticed that it is not as fuel efficient as I had hoped. What are some tips or modifications I can make to improve its fuel efficiency?

One of the simplest ways to increase fuel efficiency is by properly inflating your tires. Underinflated tires can decrease fuel efficiency by up to 3%. Make sure to check your tire pressure regularly.

Another tip is to avoid excessive idling. If you're going to be stopped for more than 30 seconds, it's more efficient to turn off your engine. This can also help reduce emissions.

Consider using a fuel additive to improve your Nissan X-Trail's overall fuel economy. There are many options available, so do some research and choose one that is compatible with your vehicle.
