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

I have noticed that my fuel efficiency on my Kia Soul has been steadily decreasing, even though I have been following all recommended maintenance and driving habits. What could be causing this issue and how can I improve my fuel efficiency?

One potential reason for a decrease in fuel efficiency could be a clogged air filter. Over time, air filters can become dirty and clogged, causing your engine to work harder and use more fuel. I would recommend checking and possibly replacing your air filter if it is dirty.

Another common reason for decreased fuel efficiency is improper tire pressure. Make sure to regularly check and inflate your tires to the recommended level. Under-inflated tires can increase friction and decrease fuel efficiency.

One more thing to consider is your driving habits. Do you frequently accelerate quickly or brake harshly? These aggressive driving habits can significantly decrease fuel efficiency. Try to drive more smoothly and avoid quick accelerations and braking.
