How can I optimize fuel efficiency in an Audi A6?

I recently purchased an Audi A6 and have noticed that it goes through fuel quite quickly. Is there any way I can improve its fuel efficiency?

One way to optimize fuel efficiency in your Audi A6 is to keep up with regular maintenance, such as replacing air filters and spark plugs. This can help improve the engine's performance and ultimately lead to better gas mileage.

Another tip is to avoid unnecessary idling and aggressive driving. This can use up a lot of fuel quickly. Instead, try to maintain a consistent speed and anticipate traffic to avoid excessive braking and accelerating.
