Why is the fuel consumption of my Volkswagen Polo increasing?

I've noticed that the fuel consumption of my Volkswagen Polo has been increasing recently. I'm not sure if it's due to my driving habits or if there is an underlying issue with the car. How can I improve my fuel efficiency?

One possible reason for the increased fuel consumption could be your driving habits. Try to drive more conservatively and avoid sudden acceleration or braking.

Another potential cause could be a problem with the engine or fuel system. It's a good idea to bring your car to a trusted mechanic for a diagnostic check.
