How can I extend the fuel economy of my Kia Sorento?

I recently purchased a Kia Sorento and I'm concerned about the fuel consumption. Is there anything I can do to improve the fuel economy?

One thing you can do is regularly check and change your air filter. A dirty air filter can decrease your fuel economy by up to 20%.

Make sure to keep your tires properly inflated. Under-inflated tires can decrease fuel efficiency by 0.2% for every 1 psi drop.

Avoid aggressive driving and excessive idling. These habits can greatly decrease fuel economy.
