How do I improve fuel efficiency in my Nissan Patrol?

I recently purchased a Nissan Patrol and have noticed that it uses a lot of fuel. I have tried driving at a consistent speed and avoiding heavy acceleration, but it doesn't seem to make a difference. What can I do to improve its fuel efficiency?

First, make sure your tires are properly inflated. Driving with under-inflated tires can increase your fuel consumption. Additionally, try to reduce the weight in your vehicle by removing any unnecessary items. Finally, getting regular tune-ups and using high-quality fuel can also help improve your fuel efficiency.
