Should one pick the oil based on FP's turbo requirements , or should one go by accepted opinion which is that a 20W-50 is just way too thick for the stock engine's clearances?

The way I see it, it may depend on which life you wish to optimize. If indeed the engine really does need 10W-30 to live its longest (200K?) and the turbo really does need 20W-50 to live its longest (75K?), then pick the one to maximize the "leakest link." It seems to me the turbo is the most fragile of the two. Maybe I am way off base.
