What is the best way to maintain the engine of a Toyota Land Cruiser?

I just bought a Toyota Land Cruiser and I want to make sure the engine stays in top condition for as long as possible. How can I properly maintain the engine to ensure its longevity?

Regularly change the oil and oil filter every 5,000 miles to keep the engine clean and lubricated.

Check and replace the air filter every 10,000 miles to prevent dirt and debris from getting into the engine.

Follow the manufacturer's recommended maintenance schedule and don't skip any scheduled maintenance tasks.

If you notice any strange noises or issues with the engine, don't hesitate to take it to a trusted mechanic for a check-up.
