Why is my Kia Stonic's fuel economy worse than predicted?

I recently purchased a Kia Stonic and was impressed by its advertised fuel economy. However, when I started driving it, I noticed that the fuel economy was not as good as expected. Can anyone explain why this is happening?

It's possible that your driving habits and conditions are affecting your fuel economy. Try driving at a steady speed and avoiding rapid acceleration and braking.

Have you considered that your car may need a tune-up? A well-maintained car can have better fuel efficiency.

Another factor to consider is the type of fuel you are using. Certain types of fuel or additives can impact your fuel economy.
