Just be aware that some race oils are formulated for just that "Race". Their additive package is different because they expect that they will be torn down frequently and changed often.

My car barely gets to the bottom end of the designed operating viscosity of 20W-50 (118-130 deg C) even at its hottest, so 20W-50 is not for me (and I imagine most others not racing or auto-x) 10W-30 is designed for 92-107 deg which is where my car runs consistently.
