How to improve the fuel efficiency of the Kia Soul?

I have noticed that my Kia Soul's fuel efficiency has been decreasing. Can you suggest any tips or improvements to help improve its fuel economy?

Regularly maintain your Kia Soul, including changing the air filter, spark plugs, and oil, as these can greatly affect fuel efficiency.

Avoid idling for extended periods of time and try to plan your trips to minimize unnecessary stops and starts.

Inflate your tires to the recommended pressure as listed in your Kia Soul's manual. Under-inflated tires can decrease fuel efficiency.
