What is the most efficient way to improve fuel efficiency in my Kia Sportage?

I recently purchased a Kia Sportage and have been looking for ways to improve its fuel efficiency. What are some steps I can take to achieve this goal? Are there any specific maintenance tasks that I should prioritize?

Regularly checking and replacing air filters is an essential maintenance task that can greatly improve fuel efficiency.

Keeping your tires properly inflated can also make a significant difference in fuel efficiency. Check and adjust frequently.

Avoid excessive idling and aggressive driving habits, as they can use up more fuel than necessary.
