The pour point should be lower.
Pour Point Refers to Oil For many oils, especially heavy oils, pour point is an important parameter because it is related to fluidity.
For some applications, a high pour point is advantageous. For example, low-pour-point oils can flow faster at lower temperatures, helping to increase equipment efficiency and productivity. In some cases, a high pour point oil may be required to ensure low temperature fluidity; in other cases, a low pour point oil may be required to increase equipment efficiency and productivity. When selecting an oil, the required pour point should be determined based on specific service conditions and requirements.
Pour point is the lowest temperature at which a liquid fuel, such as oil, can flow under specific conditions. A low pour point indicates that the fuel will still flow at lower temperatures, making it more suitable for use in cold climates or cold weather conditions. On the other hand, a high pour point means the fuel becomes too viscous and may not flow properly, leading to potential operating problems and equipment damage. Therefore, for effective fuel performance in cooler environments, a low pour point is required.
To clarify, a high pour point indicates that the material has a higher temperature at which it becomes too viscous to flow. Conversely, a low pour point indicates that the material can flow at lower temperatures without becoming too viscous. Therefore, a low pour point is preferred as it provides better flow characteristics at cooler temperatures.
This is ideal because it means the substance can flow and be used at lower temperatures without becoming too thick or solidifying. A low pour point is particularly important for products such as engine oils, lubricants and fuels as it ensures their usability in cold environments.
