How can I increase mileage on my Audi A3?

I just bought a new Audi A3 and I want to optimize its fuel efficiency. What are some effective ways to increase its mileage?

Regularly check and replace your air filter as a dirty one can decrease fuel efficiency. Also, try to drive at a steady speed and avoid excessive idling.

Keep your tires properly inflated as under-inflated tires can decrease mileage. Additionally, avoid carrying unnecessary weight in your car as it can also impact fuel efficiency.
