How to improve my Kia Niro's fuel efficiency?

I recently purchased a Kia Niro and I have been noticing that it's not getting the advertised fuel efficiency. What could be causing this and how can I improve it?

One possible reason for lower fuel efficiency could be your driving habits. Make sure to accelerate slowly and maintain a consistent speed to maximize your fuel efficiency.

Another factor could be the type of fuel you're using. Make sure to use the recommended grade of gasoline for your Kia Niro to ensure optimal performance.

Regular maintenance is crucial for maintaining fuel efficiency. Make sure to follow the recommended maintenance schedule for your vehicle, including regular oil changes and tire rotations.
