Why is my Kia Picanto experiencing low fuel efficiency?

I've noticed that my Kia Picanto's fuel efficiency has been lower than usual. What could be causing this issue and how can I improve it?

One possible reason for low fuel efficiency in the Kia Picanto could be a dirty air filter. Make sure to regularly clean or replace your air filter to improve fuel efficiency.

Check for any leaks in your fuel system, as this could also be causing your low fuel efficiency. If you find any leaks, make sure to repair them immediately.

Make sure to properly inflate your tires and regularly check for any damage or wear. Underinflated tires can greatly affect your fuel efficiency.

You may also want to consider changing your driving habits. Avoid excessive idling, aggressive acceleration and braking, and maintain a steady speed to improve your fuel efficiency.
