Crude oil is a complex mixture of hydrocarbons with varying chain lengths. Environmental regulations also play a role, as lower sulfur content requirements can alter the refining process, which in turn impacts the final pour point.
Cold Weather Engine Oil Selection: Understanding Flow and Pour Point
Pour point is usually a few degrees higher than the temperature at which the oil begins to solidify. These tests involve cooling the sample in a controlled environment and observing its behavior at specific temperature intervals.
Viscosity increases dramatically as the temperature drops, impacting efficiency. This balancing act ensures that the oil remains fluid when starting in winter and stable when running in summer.

The number before the "W" indicates performance in cold weather, while the number after indicates heat resistance. The pour point is the lowest temperature at which oil will still flow and be pumpable.
