How to reduce the fuel consumption of my Audi A8?

I have been noticing that my Audi A8 consumes a lot of fuel, is there anything I can do to reduce its fuel consumption? I have tried driving less aggressively and maintaining a steady speed but it doesn't seem to make a difference. Any suggestions would be greatly appreciated.

One of the main reasons for high fuel consumption in cars is a dirty air filter. It is recommended to replace the air filter every 12,000 miles or as per the manufacturer's recommendation. This will help improve the air flow and reduce fuel consumption. Hope this helps!

Another way to reduce fuel consumption is to keep your tires properly inflated. Under-inflated tires can cause the car to use more fuel as it requires more energy to keep the car moving. Make sure to check your tire pressure regularly.

You can also try using a fuel system cleaner to remove any deposits that might be clogging your fuel injectors. This will help improve the car's fuel efficiency. Don't forget to also check your spark plugs and replace them if necessary.
