Yes, to save fuel. So why not run lower volume all the time, or at least more of the time, and save fuel across more of the Cafe test?What do you find hard to believe? What other benefit is there? It is for load modulation.
So obviously flow plays in here at some point. How that is affected by viscosity of the chosen oil is a pure guess unless you have access to the Toyota test data.
