Jeep JL 3.6 oil

[SamJL61]

I own a 2020 Jeep JL with the 3.6. I see in some YouTube videos, some people recommend changing the viscosity of the engine oil to 5W30. What is the general consensus on doing this for better engine wear? At present I only have 15,000 miles on it.

I'm pretty sure the engineers designed them to take hours just to get the shit out of the way to do the one hour repair job

First thing that came to mind was the PCV valve on the back of the passenger head.

On a positive note/trend, some manufacturers are putting items that more likely to fail and need replacement in more accessible locations. Toyota comes to mind on a couple models/engines where they have moved items making for quick replacement if needed in the future.
