Well, plenty of proud Hyundai owners with blown Theta II motors will disagree with you. In fact, Hyundai themselves will disagree with you, even though they will never fess up to the fact that they wrongly recommended 5W-20 in in GDI engines and 5W-30 in T-GDI engines that are notorious fuel diluters. They blamed it on manufacturing debrees and what not, yet they never wanted to tell the truth because they didn't want to get into even more trouble with the EPA. In Europe, the 2.4 GDI got Shell 5W-30 ACEA A3 motor oil as factory fill and the recommended oil. Anything Turbo got 5W-40. In Europe Hyundai never had the Theta II scandal, it was a US and Canada thing. In fact, they were sending out internal service bulletins to dealers to up the viscosity on these motors on the next oil change. America is thin oil crazy, so crazy that our thin oils are thinner and less effective when compared to European thin oils.
As far as the OP's elevated wear metals, they are from bad intake filtration and from a low quality K&N oil filter. Change the air filter, change the oil filter. Use FRAM, or Purolator, or OEM. K&N is garbage, they're the Lucas Oil of the filtration industry.
