engine oil viscosity question

For a high performance turbo engine use 5W50.
0W is too thin and the hydraulic valves would be noisy.
The 50 is for not cooking the oil in the turbo at shut down.
I have always used Mobil one 5W50 full synthetic.
The cost is not an issue compared to the fuel cost.
Changing every 8.000 km. Filter every second time.
Running chipped to 280Hp (at the 200 20V).
>500 Hp at the Urq-20V and changing even sooner due to "practical/needed" 
>issue enhancing the car.
