How do I improve fuel efficiency in my Kia Sportage?

I recently bought a Kia Sportage and I've noticed that it's not as fuel efficient as I would like. How can I improve the fuel efficiency of my car?

Regularly maintain your car by checking tire pressure, using the correct oil, and getting tune-ups. This can improve your car's performance and fuel efficiency.

Try to drive at a constant speed and avoid sudden accelerations and decelerations. This can help save fuel in the long run.

Avoid excessive idling and use cruise control when possible. This can help conserve fuel and reduce emissions.
