Can you please tell me why not?
I already have.
Both those oils are heavier than the typical 5W-20 dino (QuakerState?) that Hyundai specifies.
If one wants to upgrade to a synthetic oil the main viscosity advantage one expects is to be lighter on start-up not heavier.
M1 0W-20 accomplishes that while maintaining much the same hot operational viscosity as a dino.
