Because of the different application scenarios, the required hydraulic oil viscosity is different, which also gave birth to a lot of different types of hydraulic oil, common 46 # hydraulic oil and 68 # hydraulic oil, the difference between the two is: different viscosity. In layman's terms, 46 is thinner, 68 is thicker. Generally speaking, low winter temperature, low viscosity with 46 # hydraulic oil, high summer temperature, high viscosity with 68 # hydraulic oil, special treatment.
