Why ask the question? Everyone is telling you the same thing for a reason. You should Really do your research on that engine from LONG Term improper oil usage and effects on timing chain wear, valve, CAT damage and other Oiling related issues. Your particular unit may have the variable oil pressure pump system designed around maintaining a certain flow/viscosity
Further more, the is much Less soot and tailpipe residue from the lower SAPs oil. Like the 504.00 than predecessors. Almost no tailpipe soot in my VR6 using 504.00 after 9.5k miles OCI.
This is just one example.

Thanks for the video, love the Humble Mechanic -
But my choice is to stick with a higher HTHS motor oil to protect the cam lobes and timing components in my EA888. I'm not saying 508 cannot do so, it just takes a different approach - additive technology. Be it the older specs 502/505 or newer 504 - i will choose one of these moving further. Again, i'm sure 508 will do the job while relying on the additives as well. But my choice is to rely on a thicker oil. I understand what awaits me if engine failure occurs while under warranty.
