what break-in oil? just a steady diet of brick and mortar oil will do you. I had a 1998 F-150 with a re-built engine the mechanic recommended a 500 mile oil change then afterwards said resume as normal, what is Hyundai recommending? Just follow what Hyundai has listed for this engine is it a 5W-20 or 30? and I would personally use the Hyundai/Kia filters I ran those on my 2008 Sonata they're good, stout filters. most importantly I would try my best to accelerate easily and keep RPM's under 4,000 if you did have to accelerate for a highway merge do this for at least the first one - two oil changes. I stuck with a 4,000-5000 mile oil change back in 2008-2011 until I traded the car in and used a synthetic blend that was then now today the cost difference it doesn't pay not to use synthetic. SuperTech is great oil if that's your choice.
