How can I improve the fuel economy of my Audi A6?

I've noticed that the fuel economy of my Audi A6 is not as good as it used to be. Are there any tips or tricks I can use to improve it?

First of all, try to maintain a consistent speed while driving. Sudden accelerations and braking can greatly decrease fuel efficiency. Also, make sure your tires are properly inflated and the air filter is clean. These small steps can make a big difference in fuel economy.

Consider using a higher-octane fuel. While it may be more expensive, it can actually improve your fuel economy in the long run. Additionally, try to avoid carrying excess weight in your vehicle as it can also impact fuel efficiency.
