What's the best way to take care of a Volkswagen Passat engine?

I just bought a used Volkswagen Passat and want to make sure I'm taking proper care of the engine. What are some recommended maintenance tips?

Make sure to regularly change the oil and oil filter to prevent engine damage. It's also important to check the coolant levels and get a tune-up every 50,000 miles.

Avoid aggressive driving and excessive idling to preserve the engine's longevity. It's also a good idea to use high-quality oil and fuel.

Pay attention to any warning lights or unusual noises, and get them checked by a mechanic as soon as possible. It's also important to stick to the recommended maintenance schedule.
