How do you compare ISO viscosity grades with SAE oil grades?
The following chart compares different viscosity grade classifications from ISO, AGMA, and SAE.
e.g., An SAE 10W hydraulic oil can be compared in viscosity to an ISO 32 hydraulic oil.
e.g., 2 An SAE 10W-30 oil is the equivalent of an ISO 68 or a SAE 75W-85W Gear oil in viscosity.
(Please note this is only a viscosity comparison, not a performance specification. Always check your owner’s manual for the correct grade and specification)
