What is the best way to improve fuel efficiency on my Kia Sportage?

I recently purchased a Kia Sportage and noticed that I am not getting the fuel efficiency that was advertised. Is there anything I can do to improve it?

First, make sure your tires are properly inflated. This can greatly affect your fuel efficiency. Also, try to avoid accelerating too quickly and remember to maintain a steady speed while driving.

Consider getting a tune-up for your car. This can improve your fuel efficiency and also catch any potential issues that may be causing it to decrease.

Try to avoid carrying extra weight in your car, as this can decrease your fuel efficiency. Keep your car clean and clutter-free to help with this.
