How do I improve the fuel efficiency of my Audi A6?

I recently purchased an Audi A6 and I've noticed that my fuel costs are quite high. Is there anything I can do to improve the fuel efficiency while driving this car?

One way to improve fuel efficiency in your Audi A6 is to make sure your tires are properly inflated. Under-inflated tires can decrease your fuel economy by up to 3%, so be sure to check them regularly.

Avoid aggressive driving, such as sudden accelerations and hard braking. This can waste fuel and decrease your fuel efficiency. Instead, try to maintain a steady speed and anticipate traffic.

Regular maintenance, such as oil changes and tune-ups, can also help improve your Audi A6's fuel efficiency. Make sure to follow the recommended maintenance schedule in your owner's manual.
