How to maximize fuel economy in a Kia Soul?

I've been noticing that my fuel economy in my Kia Soul has been lower than expected. What are some tips or modifications I can make to improve it?

One simple tip is to make sure your tires are properly inflated. This can improve fuel economy by up to 3%.

Also, try to avoid unnecessary idling and quick acceleration. Both of these habits can significantly decrease fuel efficiency.

Consider adding a roof rack or cargo carrier only when needed, as these can create drag and decrease fuel economy.
