What is the best way to maintain the Nissan Patrol's engine?

I have been hearing that Nissans have a reputation for reliability and durability. I want to make sure I am taking care of my Nissan Patrol's engine properly so it can continue to perform at its best. Can anyone share some tips on how to properly maintain the engine?

Regularly change the oil and oil filter according to the manufacturer's recommendations. This will ensure the engine stays clean and well-lubricated.

Check the coolant levels and make sure it is topped off. Overheating can cause serious damage to the engine.

Inspect the drive belts and replace them if they show signs of wear. A broken belt can cause the engine to fail.
