A lower pour point ensures that the hydraulic oil remains operational and maintains adequate flow characteristics even at sub-zero temperatures. This is essential for preventing oil solidification, which can lead to system blockages, reduced lubrication, and impaired hydraulic functionality. In cold climates, oils with higher pour points may become too viscous or gel-like, causing sluggish machinery response, increased wear on components, and potential system failures. Conversely, oils with lower pour points provide reliable performance, ensuring smooth operation, consistent lubrication, and efficient energy transfer in cold conditions. Selecting hydraulic oil with an appropriate pour point is therefore vital for maintaining system integrity and performance in environments subject to extreme cold.
