Hyundai has a relationship with Quaker State:
From torquenews.com:
"Hyundai Motor America has announced a relationship with Shell Oil to recommend its Quaker State branded motor oils for Hyundai's dealer network as part of a new lubricants program. ... Hyundai also uses Quaker State as the primary supplier of initial motor oil for its vehicles as they roll off the assembly line."
My Hyundai dealer uses Quaker State oil 5W20 for their oil changes.

The Santa Fe is also assembled in Alabama and Algeria according to Wiki.

All that said, QSUD is a bargain even at regular Walmart price
For cost reasons Hyundai would use QSGB 5W20 . The dealer will use 5W30 Quaker State Syn Blend on your first fill ; if doing yourself go up to synthetic QSUD 5W20 or *5W30 (either allowed for your new 2020) .
*If you plan to keep the 2020 well past 100K miles - then use 5W30 synthetic and don't look back .
You will never really know what is in the sump from the factory. QS is a guess since Hyundai has a marketing agreement with them. That agreement is no more than a paid endorsement though.
