What is the best way to maintain the fuel efficiency of the Nissan Navara?

I have owned my Nissan Navara for a few years now and have noticed a decrease in its fuel efficiency. I want to know the best practices to maintain its fuel efficiency for a longer period of time.

Regularly servicing your Nissan Navara is crucial in maintaining its fuel efficiency. Make sure to change your oil and air filter according to the manufacturer's recommended schedule.

Another tip is to drive at a consistent speed and avoid sudden acceleration and braking. This will help your truck conserve fuel and improve its efficiency.

Check your tire pressure regularly as under-inflated tires can greatly affect your truck's fuel efficiency. Properly inflated tires can improve fuel economy by up to 3%.
