How to increase fuel efficiency in my Kia Niro?

I recently purchased a Kia Niro and I've noticed that the fuel efficiency is not as good as I expected. Are there any tips or tricks to improve the fuel efficiency in a Kia Niro? Any specific maintenance tasks that could impact fuel efficiency?

Firstly, make sure to regularly check and replace your air filter. A dirty air filter can greatly decrease fuel efficiency.

Another tip is to always make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency.

Consider using premium fuel instead of regular. While it may cost a bit more, premium fuel can help improve fuel efficiency.

Avoid excessive idling and use cruise control on highways to maintain a consistent speed, both of which can help improve fuel efficiency.
