0w-20 oil is fine for street cars.
On track, I see 270F oil temps even with a Big oil cooler.
Non race oil sees a drop of 20-30% in psi strength above 275F
Means your 0w-20 becomes basically 0w-0 oil.
Then Uncle Rodney pays a visit.

Run Full Race oil, an accusump, oil cooler and it's not a problem.
