I have recently purchased a Kia Niro and noticed that my fuel mileage is not as good as advertised. What are some tips to improve fuel efficiency in my car?

Regularly check and replace air filters to improve fuel efficiency.

Avoid aggressive driving habits such as speeding and rapid acceleration, as they can greatly reduce fuel efficiency.

Try using cruise control on long highway drives to maintain a consistent speed and improve fuel efficiency.

Make sure your tires are properly inflated to the recommended pressure, as under inflated tires can decrease fuel efficiency.
