AW40 hydraulic oil is thicker than AW32 hydraulic oil. The numbers in the designations refer to the viscosity of the oil, with a higher number indicating a thicker oil. Specifically, AW32 has a viscosity of approximately 32 centistokes at 40°C, while AW40 has a viscosity of about 40 centistokes at the same temperature. Therefore, AW40 provides better performance in higher temperature applications where thicker oil is needed.
