What is the ideal oil viscosity for a Kia Ceed?

I recently bought a Kia Ceed and I'm wondering what is the best oil viscosity to use for its engine. The manufacturer suggests using 5W-30, but I've heard some people recommend using 0W-20. Which one should I choose?

The ideal oil viscosity for a Kia Ceed's engine is 5W-30. This is the recommended viscosity by the manufacturer, so you can be sure that it will work best for your car.

0W-20 is also a good option for your Kia Ceed's engine. It offers better fuel efficiency and improved performance, especially in colder temperatures.

In my experience, using a higher viscosity oil can lead to engine damage and reduced fuel efficiency. Stick to the manufacturer's recommendation of 5W-30 for optimal performance.
