With our tight tollerances and micro machining, etc isn't lower viscosity going to help the parts rather than hinder/wear? If the oil is to viscous will the drag and force pushing the parts apart cause wear on other parts?

Nissan has determined that, at 280 degrees on the recommended oil, the maximum RPM's should be reduced. Basically that's all anyone knows.

After seeing the viscosity over temperature chart, and reading all of today's posts, I'm still inclined to believe 260 degrees is a safe operating temperature. I don't believe the viscosity difference, from 220 to 260 degrees, will result in accelerated wear and premature engine failure.
