Why is my Kia Sportage experiencing poor fuel efficiency?

I recently noticed that my Kia Sportage is using a lot more fuel than usual. What could be causing this issue and what steps can I take to improve its fuel efficiency?

This could be due to a number of factors such as low tire pressure, a dirty air filter, or even a malfunctioning oxygen sensor. I suggest checking these areas first and addressing any issues.

One common cause of poor fuel efficiency is aggressive driving habits. Try to accelerate and brake smoothly and avoid excessive idling to see if this makes a difference.

If the issue persists, it may be worth getting your fuel injectors cleaned or having a professional mechanic perform a diagnostic check to pinpoint the exact cause.
