2021 5.0 which oil?

Time for my first oil change since getting my 2021 5.0 F-150. Finding multiple sources as to proper viscosity. Some say 5 W 30 and some 5 W 20. Which is correct, or does it really matter?

5W30 is correct, 5W20 was used in the previous two generations of trucks.

Owner Manuel page 593 third printing says 5W30 either MC Blend or Synthetic.
7.75 Quarts or 7.33 L
Good luck.

Thanks guys. Must have been thinking back to the 2011 I traded in. That called for 5 W 20.
