How do I improve fuel efficiency on my Kia Soul?

I recently purchased a Kia Soul and I noticed that it's not getting as good gas mileage as I expected. Is there anything I can do to improve its fuel efficiency?

Make sure your tires are properly inflated and get regular oil changes to keep your engine running efficiently.

Avoid aggressive driving and use cruise control on the highway to reduce fuel consumption.

Consider using a fuel additive to help clean your engine and improve gas mileage.
