Cloud Point vs Pour Point  Cloud point and pour point are important physical properties of any liquid fuel. Cloud point, as the name suggests is the temperature at which a cloud of wax crystals first appear in a liquid fuel when it is cooled under special testing conditions. The cloud point of any petroleum product is an indicator of how well the fuel will perform under cold weather conditions. Pour point is just the opposite of cloud point as it refers to the lowest temperature at which movement of oil is observed and the fuel can be pumped easily. As such there is only a slight difference in these two temperatures on the temperature scale but the difference between cloud point and pour point is significant in the use of any fuel. Let us find out more about these two physical characteristics of any liquid fuel. What is Cloud Point? In the industry, cloud point is taken as the temperature below which wax in fuel tends to form a cloudy appearance. This is a condition which i
