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

I have recently purchased a used Volkswagen Passat and I want to make sure the engine stays in top shape. What are some tips and tricks for maintaining the engine?

Regularly changing the engine oil and filter is crucial for keeping your Passat's engine running smoothly.

Pay attention to your check engine light and address any issues immediately. Ignoring warning signs can result in costly repairs.

Avoid harsh driving habits like sudden acceleration and braking, as this can put unnecessary strain on the engine.

In addition to regular oil changes, make sure to also check and replace other engine fluids like coolant and transmission fluid.

Consider investing in a high quality engine air filter to keep your Passat's engine clean and free from debris.
