Why is my Kia Niro getting poor gas mileage?

I recently purchased a Kia Niro and noticed that I am getting much lower gas mileage than the advertised amount. I make sure to keep my tires inflated and drive steadily, so I'm not sure what could be causing this issue. Any advice on how to improve my gas mileage?

Make sure your air filter is clean. A dirty air filter can greatly impact your gas mileage.

Check your tire pressure regularly. Low pressure can lead to decreased fuel efficiency.

Try using cruise control on the highway. This can help maintain a steady speed and improve gas mileage.
