How to improve the fuel efficiency of my Nissan Navara?

I have noticed that my Nissan Navara's fuel consumption has been higher than usual. What can I do to improve its fuel efficiency?

Regular maintenance is key when it comes to improving fuel efficiency. Make sure to change your air filter, spark plugs, and oil on a regular basis. This will ensure that your engine is running efficiently and not using up excess fuel.

Another thing you can do to improve fuel efficiency is to drive more conservatively. Avoid aggressive acceleration and braking, as these can use up more fuel.
