At 5k OCI, buy the top shelf at WM and carry on. Oil isn’t going to be the limiting factor even with a terrible engine design under those conditions.
I disagree, your comment on "the bad design" just run regular oil and don't worry about it, doesn't fly with me and others I bet. In a Hyundai/Kia motor is not necessarily the "design", as Chrysler and Mitsubishi use almost the exact design as all three are part of "The Global Engine Consortium". They use the same long block designs, but those two manufactures use "harder and more robust" metallurgy choices for all moving parts, and because of that don't have the billions of $$$s of warranty issues. There is also different fuel tuning algorithms that are in question with Hyundai/Kia that need to be accounted for. The fuel tuning and camshaft degree tuning are another area that never gets looked at. Hyundai/Kia are real soot makers.
From day one of my cars life, it has had top shelf Walmart oil, and boutique oils with most at 3,000 miles and some less. My car semi quickly formed a bad case of fuel dilution problems, to the point of the worse case I had was 1.5 Qts added fuel/moisture in a 4 liter world car sump (4.22 Qts) in my 3,000 mile dump intervals. That happened in Minnesota winters and I am a short tripper ( 10 miles to work and back. But I also warm up 4 mins each way in winter and 2 minutes in summer to expand my pistons a bit, as you know most wear/ring/cylinder happens while running with low coolant temps AND reduces Hyundai/Kia piston rock too. IE short skirts ) I also had excessive fuel dilution in the summer months even when in the 90Fs.
Oil used in it's life, All 5-30 some 5-40/040, Mobil 1 common, Mobil 1 Extended (still at 3,500 on that one) multiple times, Mobil 1 Euro FS, Redline performance 5w-30,<- got high lead from add pack jumping ( Polaris Labs analyst said who races Hyundai so I stop on that one time ) Amsoil SS, Pennzoil Ultra/Platinum/ Euro L, then I stayed with Mobil1 ESP 5-30 for about 1.5 to 2 years. After this was the height of my fuel dilution problems, that I excepted as my wear was very low/common values, testing exclusivly at Polaris Labs. Then I went to Redline Performance Euro 5-30. Within my normal for me at the time, 1,500 mile suck some diluted oil out halfway through my 3,000 dump cycle I checked the oil and I was not as high as I normally was. I finished my next 1,500 miles nd dumped and it was just a hair over the normal fill. I even PM Molukule and ask him about what he thinks could of happened. Still the same tune on the car, nothing changed but the oil. Hindsight, now it was a jammed ring pack, my hypothesis is instead of burning oil from the oil rings, I feel my top 2 compression rings were jammed and I was flooding my crankcase with fuel.
Ran on a diet of RL Euro 5-30 till covid geed of Redline (Amsoil did not raise their oil near as much as Redline) I could not justify using it every oil change. $ 17 a Qt NOPE. I stopped at $14. If I buy HPL in a 5 gallon pail I can get it for close $14./last yearish pricing. Needless to say VRP is the "cleanest/less black making oil of any oil I have ever run", not meaning black oil means bad oil. But VRP just gets dark brown and not black like EVERY other oil gets black. I only run it in my car during the late fall and early spring time, during the summer I run Motul 8100 X-Clean Gen 2 5w-40 mid saps with HPL EC every other oil change to keep my ring land clean. This fall VRP 5-30 will be going back in for the winter.
As far as using VRP on a new car or full time use, I am all for it. It is not like VRP has a horrible add pack. Do you actually think Valvoline did not know they had a winner on their hands and cheap out on a robust add pack? Is it as robust a euro certs, no. But modern day "Premium oils" are darn good oils and are pretty robust for most drivers. I am sure wishing I could/can run a 5w-30/40 VRP Euro speced fully cert-ed oil if I could.
Because I have been completely redoing my daughters 1884 farmhouse for the last 1.5 years I am putting on triple the mileage I normally do, as I have gone there for the first 1.5 years almost daily after work and weekends. I have a small break now that she finally moved in and I am burnt to the max and need a break. ALL work has been permitted. Still have another years worth of work+, windows window trim, basement windows trash and rotted. Killed the knob and tube redid 100% wiring and redid everything from the meter. All past. Tons more lighting/outlet runs in a 1884 house/not fun/but fun. 100% new all 3/4 L copper plumbing/ no 1/2 inch. Inspector was amazed, he comes in and the first thing out of his mouth was "wow, you did this industrial, good job, you did not have to go this robust" ............. Yes I did. You can do chin up on all my plumbing, hangers every 3-4ft.

New stack and all new drain runs, everything was cast iron from the late 30's/40s/50s. I pulled a ton of cast iron out of that house. Horizontal toilet runs with coded basement runs of venting runs were brutal with enclosed 2x8 floor joists. This was not fun/not fun like the fun electrical. Passed all that and still have to pico the final vent test I passed/but he technically couldn't till I get her bathroom floor in in a couple of months, as he can only pass it if the toilet is caulked to the floor the inspector knows IS the final floor. The subfloor is not, still have lots of cupping and leveling left. I am just too fried to do it now. The only thing I farmed out was a new furnace and central air that did not exist before. New ducting to meet cfm flow/as only 2 ducts upstairs from the 50's had to run 2 new 8 inch ducts up there. 95% was done by a friend of a friend who all he does is install HVAC for a living in a large HVAC company. I had too much other stuff to do as winter was coming and the house furnace was a red tager. I bought all the stuff on HVAC Direct and saved $7,000 after paying all his labor and parts. AND I was able to get a 2.5 ton Inverter A/C unit 15.2 Seer 2 where the bids I got were a low end 13 Seer 2 single stage that would of been boarder line "not in code" because it was next to neighbors bedroom window. 6 ft away. Where the inverter is so quiet, it is not a code issue. Sorry, I digress.
