I just purchased a new 2023 Kia Telluride in March. I dumped the initial oil fill at 1187km to get rid of the break-in swarf, and sent a sample in for analysis. I wanted to see if this initial factory oil had anything special in it that indicated that it needed to be in the engine for a normal run (supposed to be 6000km/6mths) to break-in. I always dump the initial fill on a new car early like this to get rid of the swarf, and have never had any problems with engine using oil afterwards, FWIW. Anyway, just thought I'd post the results for anybody that's interested.

Do you work for AECL, OPG or Bruce Power? Username would seem to imply that you might, lol

I don't see anything with this oil that would say that is anything but a standard, probably 5w-30. Which means that changing it out with fresh oil would likely be of benefit to the engine. Some people have posted in the past, that you should leave the original oil in the engine because it is special break-in oil. But this sample doesn't seem to be special.
Or does this level of Moly deem it special?
I think so, just wow on the moly. Definitely a break in oil IMO. Was probably in long enough to do what it needed to.

Nice! We probably know some of the same people. Are you active on twitter at all?
Well, I guess I stand corrected on the break-in oil aspect of this oil. Thanks KC. In that case, I hope you're right that it was left in long enough. I've put in Amsoil OE 5w-30 - hope that oil is stout enough to handle what remains of any needed break in. I'm going to change it out again at 6000 km, then go another 6000 to the next required change, then analyze that. Will post results then.
No, not on twitter - invites too many wokes, saying things that are counter to common sense thinking.
100% a break in oil. The moly proves it. No way Kia specs an oil with that moly content, unless it's for break in purposes
Yup, it's a 3.8 l DI V-6 Normally aspirated. Engine is quite strong. Moves the Telly pretty good when you want to haul ass.
Ya, I'm getting that impression now. Well, I guess maybe for my next new car, I'll believe those who say that the initial fill in cars should stay in for a while. I'm glad now that I posted the report to get this feedback.
Perhaps, or it reflects assembly lube which would be expected.
Looks like an Idemitsu Oil. The Asian auto companies are partial to that oil, lots of Moly.
FWIW, here's report done on a sample of new Amsoil OE 5w-30. It's not from an engine oil specific lab, but does show the elemental makeup of the oil.
Well, wheather it's a special break-in oil or assembly lube, the result is the same - lots of Moly to help with break-in.
It's quaker state
They make the factory fill for all kia amd hyundai engines.
A QS told me this when we bought our new santafe.
I had some nerdy oil questions.
Does Quaker State have that much moly (740 ppm)?
