Other than increased overall power output, how else do you think the car is going to go faster around the track? Unless you're going to tell me that this Royal Purple engine oil will also reducing braking distances and increase the grip of my tyres?

So how can you compare the responsiveness in different conditions and more significantly, states of ecu tune and then attribute it solely to the oil?
