Comments:
The Kia looks good at 89,925 miles. The factory warranty might be almost over, but this engine is showing no signs of slowing down. 7,500-mile oil change intervals are working just fine. Universal averages are based on around 5,800 miles on the oil and you're getting average wear metals after a longer than average run. No complaints about that. Low insolubles and silicon indicate excellent oil and air filtration. The viscosity is at the thin end of the 5W/30 range, but neither that, nor fuel at 1.0% is harmful. Just keep up the good maintenance

I think the iron is slightly high along with the silicon being slightly high and the TBN being a little low for 7500 miles. I realize the TBN was only on your prior oil change.

Looks like Blackstone. Ignore the universal avg and their comments. NAPA includes TBN for $16.00

That's actually a re-labelled Valvoline isn't it? Titanium fan here.
I noticed Kia says to either use a 5w20 or 5w30, so the slight loss in kv100 viscosity is not a problem. The 5w30 became a 5w20 somewhere later in this run. Therefore, do stick with a 5w30 to allow some viscosity loss without becoming too thin. Some VII's got shredded & fuel dilution affected it some to nudge viscosity down.

Silicon wasn't too high. A lot of that is probably lab error combined with about 15 ppm or so anti-foam additive.

Both the 5W-30 and 5W-20 look good. Thanks for sharing.

There is debate about possible differences in the additive package, but NAPA oil is definitely supplied by Valvoline. Even says so on the back of the bottle and has the Valvoline phone number listed for any product questions. It certainly looks very close based on the UOA, especially when keeping in mind that the previous UOA was the 5w-20 variant and prior to that I had been running the older Valvoline SynPower with a completely different additive pack.

One other different thing about this run: I used CRC's IVD intake valve cleaner which is sprayed in the throttle body with the engine running. I had expected to see higher silicon numbers as a result of this, but it was actually a bit lower than the previous run.

Looks pretty good Jim. I'm not giving it more stars due to shearing and would have liked to see another 50% dose of either Boron or Moly.

I know - I'm nitpicking here. It stood-up well to the D.I. engine for 7.5K.

it might not be 100% identical, but it's probably 95% identical to Valvoline synpower. PQIA showed a few differences here and there, but it's still a matter of discussion as to if those are NAPA specific tweaks, manufacturing margins, or minor changes in formulation over time.
