But those failures could be prevented by replacing the bearings with a refresh. The issue is that unless you need an engine to last a long period of time, refreshing it would be more cost effective.
On the subject of the cooler. Wouldn't having a better cooler cancel the benefits of running thicker oil? Wouldn't running a lighter fluid provide better flow and protection to areas with smaller passages? I know the argument about tracked(daily drivers) cars need thicker oil, but that is considering that oil will rise much higher then stock, lowering its weight to a more suitable thickness.
Also more heat taken from the oil = more heat in the coolant = higher average engine temperate. No idea if that is more suitable then a high but acceptable oil temperature with lower coolant temperatures.
