Multi viscosity hydraulic fluid
Posted by Ed from Omaha, NE, US on May 8, 2007
What advantages would a multi viscosity hydraulic fluid have over a traditional mono grade hydraulic fluid?
Multigrade hydraulic fluids have higher viscosity index. This means the fluid undergoes less viscosity change in response to temperature changes. This will result in the fluid maintaining it's critical characteristic, even in extreme hot conditions.
