Using hydraulic fluid with significantly lower viscosity than specified creates several critical risks. Viscosity is a fluid's resistance to flow. Lower viscosity means the fluid is thinner and flows more easily. First, it reduces the fluid's ability to maintain a sufficient oil film between moving parts, such as gears and pistons within hydraulic pumps and cylinders. This leads to increased friction and wear as metal surfaces come into direct contact, causing premature component failure. Seco....
