I think this is a weak QS oil that Hyundai uses to facilitate break in. Look how low the add package is on an engine that is so new with so few miles on the oil.
It's most definitely just there to stop the engine from seizing up or building sludge and offers little protection in terms of wear so the engine can break in properly.
That is my thought...
Nice to see Blackstone confirm the Silicon is from gaskets like Terry has been telling me is common with that and copper on my Santa Fe 2.7L V6 being from gasket materials Hyundai/Kia and some Lexus use.
