The demands that extremely low temperatures place on industrial and mobile machinery provides a challenge for machine lubricants. Cold Weather hydraulic oil that is labeled as an ISO VG 46 oil addresses these extra stresses and absorbs the increased strain put on these machines. These oils generally benefit from a High-Viscosity Index (HVI) and can be used in applications that aren't constantly exposed to sub-zero temperatures, but may experience an occasional drop in temperature. However, these oils are designed to operate efficiently and consistently in cold weather.
ISO VG 46 Cold-Weather Hydraulic Oil has a midpoint viscosity of 46 mm2/s (or cSt).
