Well to elaborate on my previous post i get my oil at walmart. But since your car has a substantial warranty i myself would most likely have the dealership do the oil change so that an ireffutable maintainace record is established if anything might hapen to the engine or other lubricated parts during that warranty period.
Love these cars. Where are the pictures?

Heres a few. Looks like we have similar taste in vehicles as well if you check my sig.

Man, that is gorgeous. I haven't seen a yellow one yet. All the one's around here are red or grey. Great looking car! Congratulations.

We got the AWD since it will be my wife's daily and we do get snow in Cincinnati. The awd is rwd bias though and has great driving dynamics.

Sorry so long to respond...
Oil temp is high. Mainly due to the compact nature of the engine compartment. The oil cap says 5w-30 on the GT and 0w-30 on the 2.0T, nobody really knows why. It was mutually agreed in training among Techs and instructors that Xw-40 should be used if a GT is driven any harder than to your Church functions. They do in fact use an oil cooler but it's cooled by engine coolant, not air. So the oil cooler can only do so much. And no, we are not privy to bearing clearances, they are proprietary apparently. I would think they would be similar or identical to all the Lambda V-6's, and are selective rod bearings which are only serviceable in the reman program. We do not build short blocks in a Kia house. So no reason for a tech to sweat the bearing clearances. For this I am thankful, they don't pay well even to assemble a long block.

GC 0/40 or GC 0/30 or Redline or M1 15/50 on track days.

Our 2.3 EcoBoost Explorer is a real heat producer in the engine compartment. With the 2 UOA's It showed oil shearing without outward signs of fuel dilution. The Mobil 1 5W-30 after 7,000 miles was at least just still in the 30 weight viscosity category. The Motorcraft 5W-30 after 4,275 miles was firmly into the lower 20 weight viscosity family. I posted these in the UOA section previously.

Good info on the shear difference going on. It would be interesting to see more data comparing how different oils sheared down in the same engine like you showed above.
On a side note, I wonder how much testing is done on the oil shearing in actual use conditions in cars that manufacturers are recommending 0W-16? Especially with higher OCIs and in DI engines that typically have higher fuel dilution.

My interpretation of the chart was that 0w 30 or 40 was ok.

There is also Pennzoil Euro 5w-40 A3/B4. Shell and Mobil also make 5w-30 E6 HDEOs in SN that lack GF-5 due to higher HTHS. Castrol has one as well, but very hard to find and lacks the SN, of all things. Chevron should have one as well.

Thats for the 4 cylinder and not the v6.

FWIW: If it where mine (yellow Kia GT2 AWD), I'd put the same fantastic Castrol 0W-40 oil and Fram XG series filter that I run in my turbo/tuned Optima SX. I'd also keep that oil/filter changed every 5K miles and run it on Top Tier 93 octane gas.

This seems to be the only gas-engine-specific and easy-to-find 5W-40 in US:
https://www.walmart.com/ip/Castrol-EDGE-5W-40-Full-Synthetic-Motor-Oil-5-QT/145736795
If you want to go with 5W-30, it needs to be ACEA A5/B5. Mobil 1 and Pennzoil Platinum are good choices.
I wonder why 0W-40 is not recommended. Too much viscosity-index improver (VII) may cause intake-valve-deposits problems in GDI engines? If that's the case, 5W-30 is a better choice than 5W-40 for GDI because it has less viscosity-index improver.
Regarding amount of VII in Mobil 1 oils, see my table for the A_Harman index:

I may just go with M1 5w30 EP since thats what I run in my truck. Easy to find at about every store as well.

It's probably a good choice for this engine. It also has a little less VII than the vanilla M1 5W-30.
