What is the best way to maintain fuel efficiency in a Kia Sportage?

I recently purchased a Kia Sportage and I want to make sure I am taking the best care of it. What steps can I take to maintain fuel efficiency and save on gas expenses?

First and foremost, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by up to 25%. Check your owner's manual for the recommended tire pressure.

Regularly change your air filter. A dirty air filter can decrease fuel efficiency by up to 10%. Make sure to replace it every 12,000-15,000 miles.

Avoid aggressive driving and excessive idling. Driving at high speeds, rapid acceleration, and prolonged idling can significantly decrease fuel efficiency.
