I don't see the point of any skepticism of this claim by SFP. BMW clearly did some optimization work (arrived at a true global optimum across all or even many variables, probably not) in the oil system and they did so using the specified 10W-60 oil. The statement is almost a tautology...
Now that being said, the system is also inherently robust to changes in viscosity - it must be since oil viscosity changes with age, temperature, contamination, etc.
