How do I properly maintain my Nissan Patrol?

I recently purchased a Nissan Patrol and I want to make sure I am taking good care of it. What should I be doing to maintain its performance and longevity?

Regularly check and change the engine oil and filters to keep the engine running smoothly. Also, make sure to use high quality fuel and don't neglect regular tune-ups.

Keep an eye on the transmission and differential fluids and have them flushed and replaced according to manufacturer's recommendations. This will prolong their lifespan and prevent costly repairs.
