How can I increase the fuel efficiency of my Nissan Navara?

I have been noticing that my Nissan Navara is consuming a lot of fuel lately. What could be the cause and how can I improve its fuel efficiency? Any tips or advice would be greatly appreciated.

Regularly check your tire pressure and make sure they are inflated to the correct level. Under-inflated tires can significantly decrease fuel efficiency.

Avoid carrying excess weight in your Navara. The heavier the load, the more fuel is needed to move the vehicle.
