Why is my Kia Soul's gas mileage decreasing?

I have noticed that my Kia Soul's gas mileage has been decreasing over the past few months. What could be causing this?

It is important to regularly check and maintain your tire pressure, as low tire pressure can greatly impact your gas mileage. Make sure to check your tire pressure at least once a month.

Another factor that can affect gas mileage is your driving habits. Avoid aggressive driving, such as rapid acceleration and braking. This can use up more fuel than necessary.

Check your air filter, as a dirty air filter can decrease fuel efficiency. It is recommended to replace your air filter every 12,000-15,000 miles.
