Why is my Kia Sorento's MPG decreasing?

I used to get great gas mileage in my Kia Sorento, but recently it's been decreasing. What could be causing this and how can I improve it?

One possible reason for the decrease in MPG could be a dirty air filter. I would suggest checking and changing the air filter if needed.

Another factor could be the type of fuel you are using. Make sure you are using the recommended fuel grade for your Kia Sorento.

If you've been using your air conditioning more frequently, it could also contribute to the decrease in MPG. Make sure to only use it when necessary to save on gas.

Have you checked your tire pressure recently? Under-inflated tires can decrease MPG. Make sure to keep them properly inflated according to your owner's manual.
