What is the best oil type for a Kia Picanto?

I am a new owner of a Kia Picanto and I am unsure about the best type of oil to use for my car. I've heard conflicting opinions about conventional vs synthetic oils. Can anyone offer some insight?

It's recommended to use synthetic oil for the Kia Picanto as it provides better protection for your engine. I've been using it for years and have had no issues.

I've always used conventional oil for my Picanto and have had no problems. In fact, it's cheaper than synthetic oil.

As an experienced mechanic, I highly recommend using 5W-30 synthetic oil for optimal engine performance and longevity.
