What statement is true concerning viscosity index as it applies to lubricating oils?
An oil with a high viscosity index would have a relatively high rate of change of viscosity as the pressure changes.
An oil with a high viscosity index would have a relatively low rate of change of viscosity as the temperature changes.
An oil with a high viscosity index would have a relatively low rate of change of viscosity as the pressure changes.
