How do I improve the fuel efficiency of my Audi A1?

I recently purchased an Audi A1 and I'm concerned about the fuel efficiency. Are there any tips or tricks I can use to improve it?

First, make sure to properly maintain your car by regularly changing the oil and air filter. This can greatly affect fuel efficiency.

Avoid idling for long periods of time and try to combine short trips into one longer trip. This can help reduce fuel consumption.

Consider using a fuel-saver device or app to monitor and improve your driving habits. This can help save on fuel costs in the long run.
