Why does my Kia ProCeed have a poor fuel efficiency?

I recently noticed that my Kia ProCeed is not getting the same fuel efficiency as it used to. What could be causing this issue and how can I improve it?

It could be due to a dirty air filter or faulty oxygen sensor. Have these components checked and replaced if necessary for better fuel efficiency.

Make sure you are regularly maintaining your tire pressure and getting regular oil changes. This can greatly impact your car's fuel efficiency.

Consider avoiding aggressive driving habits like rapid acceleration and hard braking, as they can significantly decrease your car's fuel efficiency.
