I love my new Veloster and want to take good care of it! It has the same 1.6L GDI engine (with "direct fuel injection") as the more common Hyundai Accent. I am aware there is controversy regarding whether frequent early oil changes are beneficial for a new car. My manual does not really address this issue. So I have a few questions which may sidestep the primary controversy....
Is it possible an early oil change or two (much sooner than Hyundai's recommended OCI) could do more harm than good? Does the factory fill contain additives which aid in the engine break-in process? If so, what are they and when (or at what odometer reading) do they cease to be important?
I have read a few forum posts claiming the Veloster's factory fill is Quaker State synthetic oil (the car is made in Korea), but these posts may be just repeating a single source rumor. My dealership's service adviser said the factory fill is not synthetic and Hyundai does not recommend using synthetic oil. I really don't have much reason to believe him either, however. Has anyone analyzed the factory fill to determine whether it is synthetic? Is it possible that synthetic oil would not protect this engine as well as dino oil?
If the factory fill is synthetic, then quite a few new car owners are replacing their synthetic FF oil with dino oil soon after taking possession of their vehicle to flush out suspended particles in the oil caused by the engine break-in process. Is it possible that synthetic oil with suspended particles in it provides better protection than fresh dino oil?
