What are some maintenance tips for a Nissan Patrol's engine?

I recently bought a Nissan Patrol and want to make sure I properly maintain the engine. What are some things I should keep in mind and how often should I perform maintenance?

Regularly check and change your oil every 3,000-5,000 miles to keep your engine running smoothly. Use high-quality oil to ensure maximum protection for your engine.

Don't neglect regular oil filter changes, as this can affect the performance and longevity of your engine. It's recommended to change it every other oil change.

Check your air filter and replace it if it's dirty. A clogged air filter can restrict air flow and decrease engine performance.
