I have the SX model (1.6L Turbo)

The oil cap states 5w-30
The manual states 5w-30 or 5w-40
The Kia website states 5w-30

I've had a total of 4 oil changes since owning the vehicle (over a year).
The dealership has been putting in 5w-20
Does anyone have any thoughts? Understanding of this?
Looking online lots of oil forums are saying 5w-20 is bad for turbo GDI engines.

Any insight would be appreciated.

Find another dealer. The dealer i used to go to used 5W20 in my turbo Forte. It's supposed to be 5W30 or 5W40 in the turbo engines.

Yep my selling dealer was going to charge me extra for synthetic if I wanted it on a nc first service. After a short email exchange where I stated the sx 1.6 turbo calls for synthetic, he agreed and I got my nc service. They also use Petro Can synthetic oil which as far as I can tell is not ACEA A5 certified like manual states. I perform my own maintenance, that I enjoy doing, so with all the misinformation from dealer's I'm not concerned with warranty disputes,
