Why is my Kia Sorento experiencing a decrease in fuel efficiency?

I have noticed that my Kia Sorento's fuel efficiency has been decreasing over the past few weeks. What could be causing this issue and how can I improve my fuel efficiency?

It is normal for a car's fuel efficiency to decrease over time, especially if you are not maintaining it properly. I recommend checking your tire pressure, changing your air filter, and getting a tune-up to improve your fuel efficiency.

Have you recently changed your driving habits? Aggressive driving and excessive idling can greatly decrease your fuel efficiency. Try driving more smoothly and avoiding idling for long periods of time.

Another factor that can affect your fuel efficiency is the type of fuel you are using. Make sure you are using the recommended fuel type for your Kia Sorento and avoid using cheap or low quality fuel.
