My apology if this has been covered recently...
I am seriously considering purchase of the above mentioned car, so being a BITOGer I naturally wanted to check on the recommended oil.
From Kia: API SM or above*3, ILSAC GF-4 or above*4, ACEA-A5 or above
Tried entering Make and model in Mobil 1's website:
'Based on what you've told us, your vehicle manufacturer recommends a 5W-30 or 5W-40 viscosity and oil that meets ACEA A5/B5. We currently do not offer any motor oils in the United States that meet these specifications'.
It's the 'ACEA-A5 or above' that Mobil 1 doesn't meet. I haven't checked other oil brand's yet, but given Mobil's size in the market you would think that if they don't have it other oil companies won't yet either. Is this spec new, and what does it mean? Would my local Kia dealer even carry an oil that meets it? Have any other auto brands listed this spec?
Thank you for your input...

"Check out the Pennzoil site .... it shows Ultra & Platinum 5W30 meet the ACEA A5 spec."
Thanks, I checked their site. I've seen it on sale occasionally at Walmart, and it seems to be well regarded here at BITOG. Did some research on this spec, seems to do more with fuel economy than engine wear. Still surprised that Mobil 1 doesn't meet this spec..
M1 may very well meet it, and has in the past. Castrol dropped the spec for at least a time, too. There were so few vehicles in North America calling for A5/B5, it seemed the specs began to drop off a bit, and then with the revision to the B side, we saw some being dropped, too. Now, we see more vehicles calling for A5/B5, and the oil companies are reacting at the expected glacial pace. 
What does Kia use as a service fill, Quaker State? QSUD is no longer technically A5/B5, either. Some of these manual recommendations are written in such a silly fashion. The notion of a 5w-40 in A5/B5, for instance, is pure baloney.

Agreed.. The Kia manual shows viscosities up to 20w-50, but still with the 'ACEA-A5 or above' spec. An (admittedly) quick search didn't turn up any such oil...

Pennzoil Platinum and Valvoline Synthetic show as meeting A5/B5 on their websites.
I would have zero issue using any top brand syn with d1G2 cert or a 5w40 A3/B4 euro oil.

Wemay's point is quite valid. If it's a dexos1 oil, it's probably going to be more than sufficient. GM should sponsor BITOG for all the dexos1 recommendations we pass out. Look under the hood of your car. It probably says that Kia recommends Shell or Quaker State oil.
Quaker State's web site state that their synthetic oil meets your car's requirements.
However, I would consider using Mobil 1 European Car Formula.
I'll pass on a Hyundai/Kia. Not as well made as a Japanese car.

I looked up this engine on Amsoil website application guide and there was no listing yet for 2018 model, so then I looked up for a 2017 Sonata 2 Liter turbo and they only recommended their top tier Signature Series 5W-30, which says something to me about the demands this engine makes on the oil. Turbocharged with direct injection is apparently pretty tough on the oil.
