What is the recommended engine oil for the Kia Stonic?

I recently purchased a Kia Stonic and I am unsure of what type of engine oil to use. Can you recommend the best type of engine oil for optimal performance and durability?

It is important to always refer to the owner's manual for specific recommendations, but based on my experience, I would recommend using a fully synthetic 5W-30 engine oil. This type of oil offers excellent protection and can improve fuel efficiency.

I have been using a semi-synthetic 10W-40 engine oil and have not had any issues so far. It is also a more budget-friendly option compared to fully synthetic oils.

I have been using a premium synthetic 0W-20 oil and have noticed a significant improvement in engine performance and smoothness. It is a bit more expensive, but worth the investment in my opinion.
