How can I improve the mileage on my Kia Soul?

I've noticed that my Kia Soul's gas mileage is not as good as it used to be. Is there anything I can do to improve it?

One way to improve the gas mileage on your Kia Soul is to regularly check and replace the air filter. A dirty air filter can decrease fuel efficiency.

Consider using a fuel additive specifically designed to improve fuel efficiency. There are many options available on the market.

Make sure your tires are properly inflated. Under-inflated tires can greatly decrease gas mileage.

Avoid aggressive driving habits such as speeding and sudden braking. This can use up more gas than necessary.
