What is the best way to increase the fuel efficiency in my Audi?

I have been noticing that my Audi's fuel efficiency has been decreasing recently. What are some tips or adjustments I can make to improve it?

One of the best ways to increase fuel efficiency in your Audi is to regularly maintain and check your tires. Under-inflated tires can greatly decrease fuel efficiency. Make sure to also keep up with fluid changes and engine maintenance.

Another important factor for fuel efficiency is driving habits. Avoid rapid acceleration or heavy braking, as this can use up more fuel. Also, try to maintain a consistent speed when on the highway instead of constantly speeding up and slowing down.

Consider using cruise control when driving on the highway, as this can help maintain a consistent speed and improve fuel efficiency. Also, try to avoid carrying unnecessary weight in your car, as this can also use up more fuel.
