How can I properly maintain my Toyota Land Cruiser's engine?

I just bought a Toyota Land Cruiser and I want to make sure that the engine is properly maintained to ensure its longevity. Can someone give me some advice on what maintenance tasks I should perform and how often I should do them?

Regularly change your engine oil and oil filter every 5,000 to 7,500 miles to keep your engine running smoothly. Make sure to use high quality oil and filters.

Check your engine's air filter every 10,000 miles and replace it if it looks dirty. A dirty air filter can decrease fuel efficiency and damage your engine.

Don't forget to regularly inspect your engine belts and hoses. If you see any cracks or tears, they should be replaced as soon as possible to prevent engine damage.
