Why is my Kia ProCeed's gas mileage decreasing?

I noticed that the gas mileage on my Kia ProCeed has been decreasing over the past few months. I've been getting regular maintenance and I don't have any warning lights on. What could be causing this decrease in gas mileage and how can I improve it?

It's possible that your air filter is clogged and needs to be replaced. This can greatly affect your gas mileage. I would recommend checking it and replacing it if necessary.

Another possibility is that your tires are not properly inflated. This can cause drag and decrease your gas efficiency. Make sure your tires are inflated to the recommended pressure.

If your Kia ProCeed has a turbocharged engine, it's possible that the turbo is malfunctioning and causing a decrease in gas mileage. I would suggest having it checked by a mechanic.

Another factor that can affect gas mileage is driving habits. Are you frequently speeding or accelerating quickly? This can significantly decrease your gas efficiency. Try practicing more conservative driving habits and see if that helps.
