How to improve fuel efficiency in the Kia Niro?

I've noticed that my Kia Niro uses more gas than advertised. Is there any way to improve its fuel efficiency?

First, make sure your tires are properly inflated. Underinflated tires can significantly decrease your fuel efficiency. Also, avoid unnecessary idling and practice smooth driving habits.

You can also try using a higher octane fuel or adding fuel additives to clean the engine and improve fuel efficiency.

Regular maintenance and tune-ups can also improve your car's fuel efficiency. Make sure to follow the recommended service schedule.
