How can I increase my Audi A4's fuel efficiency?

I recently purchased an Audi A4 and I love it, but I'm concerned about its fuel efficiency. What steps can I take to improve it?

Make sure your tires are properly inflated as that can greatly affect fuel efficiency. You should also try to avoid unnecessary acceleration and heavy braking.

Regular maintenance, such as oil changes and air filter replacements, can also greatly improve fuel efficiency.

Consider reducing the weight in your car by removing any unnecessary items from the trunk or roof rack. This can also help improve fuel efficiency.
