I got some additional details on Sunoco Ultra Synthetic Motor Oil:
Sunoco Ultra Full Synthetic 0W-20 ILSAG GF-5 Engine Oils are specially formulated using synthetic base oils and high performance additive packages to provide superior performance benefits over conventional engine oils. These oils are formulated for excellent oxidation stability for long product life, superior low-temperature properties to insure protection during cold starts, lower volatility for reduced oil consumption, and excellent resistance to viscosity breakdown.
These products are designed to meet the most demanding lubrication requirements of today's naturally aspirated, turbo-charged and super-charged gasoline fueled and flex-fueled engines. It is recommended for Original Equipment Manufacturers (OEM) such as Toyota, Honda, Hyundai and others for some hybrid vehicle applications and a limited number of low temperature applications.

Now that I got all this information, I am glad that my dealer uses this oil in my 2018 2.0Turbo Hyundai Santa Fe Sport.
