Well, if his turbo uses a labyrith type seal, then viscosity will be a major factor in causing it to weep, esp during heat soak conditions. These seals directly rely on an oil's resistance to flow (viscosity), and heat soaking in a turbo bearing section would make quick work of a 0w20 causing it to travel further and further out into the exhaust turbine. You are right though, I can't absolutely say with certainty that that will happen, but it has happened.
