How to improve fuel efficiency on my Kia ProCeed?

I have been noticing that my Kia ProCeed's fuel efficiency has been decreasing lately. Is there anything I can do to improve it?

Regularly check and replace your air filter. A clogged air filter can decrease fuel efficiency.

Avoid aggressive driving and excessive idling. These habits can significantly impact fuel efficiency.

Make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency.
