Modern multi-grade oils, such as 5W-30 or 0W-20, are designed with additives that prevent the wax molecules within the base oil from crystallizing. They also flow more readily at low temperatures and maintain their viscosity better under high heat.
Preventing Winter Oil Viscosity Problems with Additive Technology and Proper Grades
They have a more uniform molecular structure, which means they are less likely to wax or gel in the cold. In extremely cold regions, opting for a 0W or 5W viscosity provides the best protection.
Check your owner’s manual for the correct cold-weather oil grade. Store vehicles in a garage when possible to shield the engine from the worst of the cold.
