I don't really understand a statement that says Mobil 1 is fine, but it's viscosity is lower than it should be....that makes it not fine.
Oil really only needs to do one job - maintain it's viscosity to keep metal parts sliding past each other without wearing them out, so maintain proper viscosity for the engine's operating temperature range and show as little metal wear as possible.. If the viscosity is too low, the metal wear will suffer.

Wear metals, contamination, add pack, detergents, and oil life were / are in the green; if the viscosity had degraded to the degree that you are concerned, I imagine it would be reflected in the UOA report.

Does anyone have a reference to or quote where @Charles Navarro /LNE is now recommending DI40 for the M97? (The LNE website is still recommending DT40 or FR50. (https://lnengineering.com/oil.html ) I've written to LNE but no response yet. It's oil change time and I want to get the current best/recommended oil.
