How to improve the mileage of my Kia Ceed?

My Kia Ceed seems to have lower mileage than what is advertised. I was wondering if there are any tips to improve its fuel efficiency?

First and foremost, make sure your tires are properly inflated. Under-inflated tires can significantly decrease your mileage. Additionally, try to avoid accelerating too quickly and maintain a steady speed on the highway.

You might also want to check your air filter. A dirty air filter can reduce your mileage by up to 10%. Make sure to replace it regularly to improve your car's fuel efficiency.

Try not to carry unnecessary weight in your car. The more weight your car has to carry, the more fuel it will consume. So, make sure to declutter your trunk and remove any unnecessary items.
