What is the pour point of an oil?

The pour point of an oil refers to the lowest temperature at which it can still flow and is typically associated with the point at which the oil begins to crystallize. This temperature is crucial for understanding the performance of oil in cold conditions, as it indicates the temperature limit for the oil's liquidity. Below this point, the oil may thicken or solidify, which can impede its movement through pipes and components in heating systems.

Understanding the pour point is essential for technicians when selecting fuels for systems that must operate in varying environmental conditions. It helps them ensure that the oil will remain fluid and functional, enabling proper operation and efficiency.
