How can I increase the mileage of my Kia Soul?

I have noticed that my Kia Soul's mileage is not as efficient as it used to be. What steps can I take to improve my car's fuel efficiency?

Regularly check and change the air filter as clogged or dirty filters can greatly decrease fuel efficiency.

Inflate your tires to the recommended pressure listed in your owner's manual. Under-inflated tires can decrease mileage by up to 25%.

Avoid idling as it wastes fuel and can decrease your car's mileage.

Use cruise control on the highway to maintain a steady speed which can improve fuel efficiency.
