Is there a way to improve the fuel efficiency of my Kia Rio?

I recently purchased a Kia Rio and I've noticed that I'm not getting as much fuel efficiency as I was expecting. Is there any maintenance tips or modifications I can make to improve the fuel efficiency?

Regularly checking and replacing air filters can significantly help improve fuel efficiency.

Maintaining proper tire pressure and doing regular tune-ups can also play a big role in improving fuel efficiency.
