What's the best way to maintain the longevity of my Volkswagen Passat's engine?

I just bought a used Volkswagen Passat and I want to make sure the engine lasts for as long as possible. What steps should I take to maintain its longevity?

Regular oil changes and routine maintenance checks are essential for keeping your Passat's engine running smoothly. Be sure to follow the manufacturer's recommended maintenance schedule.

Avoid aggressive driving and excessive idling, as these can put extra strain on your engine and lead to premature wear and tear. Also, be sure to use high-quality fuel for optimal performance.

Pay attention to warning signs such as strange noises or changes in engine performance. These could be indicators of underlying issues that should be addressed before they become more serious.
