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

I recently purchased a Volkswagen Passat and I want to make sure I'm properly taking care of the engine. What are some maintenance tips and best practices I should follow?

Regular oil changes and tune-ups are essential for maintaining the health of your engine. Be sure to follow your vehicle's recommended maintenance schedule.

Keeping your engine clean is also key. Make sure to regularly check and replace air filters and avoid driving on dusty or dirty roads as much as possible.

Don't forget to regularly check your vehicle's fluid levels, including coolant, transmission fluid, and brake fluid. Low levels can lead to engine damage and other issues.

In addition to regular maintenance, listen for any abnormal sounds coming from your engine and address them promptly. It's always better to catch an issue early before it turns into a bigger problem.
