How can I extend the lifespan of my Volkswagen Touareg's engine?

I recently purchased a Volkswagen Touareg and I want to make sure I am taking proper care of the engine. What maintenance routines should be done to ensure the engine lasts as long as possible?

Perform regular oil changes and use high quality synthetic oil.

Avoid harsh driving and excessive idling which can strain the engine.

Monitor the engine temperature and coolant levels to prevent overheating.

Consider using a fuel stabilizer to prevent build up in the engine over time.
