How can I improve the mileage of my Audi A3?

I recently purchased a new Audi A3 and I noticed that the mileage is lower than expected. What are some ways to improve the mileage and get the most out of my car?

Regularly check and replace your air filter to ensure proper airflow and improve fuel efficiency.

Avoid aggressive driving and maintain a consistent speed to reduce fuel consumption.

Make sure your tires are properly inflated to the recommended pressure. Underinflated tires can increase fuel consumption.
