Reading bearing manufacturer data on lubrication shows that high rpm requires lower viscosity (thinner) lubrication, and low RPM requires higher viscosity lubrication. It was explained that that the lubrication has to "be in the way" when needed, and also be able to "get out of the way" so the bearing elements can pass. This supports longer bearing life in aggressively driven cars that have engine oil in the bearing. So to the folks out there with 200K+ on their cars, we know how you drive.
