What's the best way to increase fuel efficiency in a Kia Sorento?

I recently purchased a Kia Sorento and I've noticed that I'm not getting as much mileage as I expected. What can I do to improve the fuel efficiency?

Regularly checking and replacing your air filter can greatly improve your fuel efficiency. It's an easy and inexpensive fix that can make a big difference.

Properly inflating your tires can also help improve fuel efficiency. Make sure to check your tire pressure at least once a month and adjust accordingly.

Avoid aggressive driving and sudden starts and stops. This can waste fuel and decrease your overall efficiency.

Consider using a fuel additive or cleaner to remove any build-up in your engine and improve your fuel efficiency.

Regular maintenance, such as tune-ups and oil changes, can also improve your fuel efficiency. Make sure to follow your vehicle's recommended maintenance schedule.
