What is the most efficient way to decrease fuel consumption on my Audi A8?

I have noticed that my Audi A8 uses a lot of fuel, is there anything I can do to decrease its consumption?

The best way to decrease fuel consumption on your Audi A8 is to ensure that your tires are properly inflated. This reduces drag and helps improve fuel efficiency.

Another way to save on fuel is to avoid unnecessary weight in your car. Remove any heavy items from your trunk or back seats.

It's also important to keep up with regular maintenance, such as oil changes and tune-ups, to keep your engine running efficiently.
