What is the relationship between the cold filter point, pour point, and the components of the oil?

For the oils obtained from primary processing – such as normal oil, grade 1 oil, grade 2 oil, grade 3 oil, reduced grade 1 oil, reduced grade 2 oil, reduced grade 3 oil, and residue-free oil – as well as catalytic diesel produced through secondary processing, what is the relationship between their cold filter points and freezing points? Do these values decrease step by step? Apart from being determined by the properties of the crude feed oil, for feeds that are normal paraffin, naphtha, gas oil, reduced paraffin, and catalytic diesel, how can the cold filter point of the refined diesel after hydrocracking be adjusted? Detergents can lower the cold filter point in a short period of time! The cold filter point is related to the wax content in the feedstock, and it reflects the low-temperature fluidity of the oil. Additionally, does paraffin-based crude oil have a very low cold filter point? Is it closely related to the components? I hope experienced friends can give some guidance!
