Nascar engine oil viscosity?

Just wondered if anyone knows what ';weight viscosity'; the nascar cars use for motor oil? And any particular brand?Nascar engine oil viscosity?
Multigrading is not critical for racing as the engines are warmed up carefully. They probably run a 5 or 0 weight to minimise drag on the crankshaft. Oil temperature is precisely controlled with a thermostat and cooler assemblyNascar engine oil viscosity?
I have read that some of the teams use Mobil 1 0W-30 with Sypersyn. And then they will use the same or 15W-50 for the race. But that differs with each team. This is what Penske runs.
Well it depends on weather track and point in the race schedule. Extremely cold we will run 5 weight oil under normal conditions we will run 000weight for qualifying but now with the impound rule we run 0 weight.
