I run Penzzoil Platinum 5W-20/30 . Works really well.
If I can suggest, use the OE Blue Hyundai filter. Built liked a tank, and handles the pressure swings of the Hyundai engines.
The Fram Ultra speced for Hyundai went back to Fram's engineers about 3-4 years ago to specifically address, "the Hyundai issues" so the Fram Ultra is another filter to run with far better filtering the the OEM filter. The Hyundai Fram Ultra can flow 20 plus gallons a minute, far more then the cars pump flows.
