Pour point is the lowest temperature at which oil can still flow. It is a critical property for lubricants and fuels that are to be used in cold climates. Below this temperature, the oil can become too thick or solidify, which can prevent start-up and lubrication.
The analysis is performed by gradually cooling the sample and observing when the oil stops moving.
The customer receives an assessment of whether the oil is suitable for use in low temperatures and can plan for seasonal replacement or adjustment of oil type.
