Regular oil changes with the manufacturer-recommended viscosity are the simplest defense against these cold-weather challenges. These advanced formulations utilize additives that inhibit wax crystal growth, ensuring the oil remains pumpable.
OEM Oil Specs for Cold Weather: Viscosity and Additives Explained
Viscosity: What Matters for Engine Start While the pour point defines the temperature at which an oil stops flowing, viscosity is the measure of its resistance to movement. This crystallization is the primary reason for the increase in thickness, or viscosity, that drivers might notice when the temperature plummets.
This delay is the primary cause of premature wear during the initial seconds of operation. Modern multi-grade oils, such as 5W-30 or 0W-20, are designed to act like their first number at cold temperatures and their second number at operating heat.

Furthermore, old or degraded oil with a high concentration of contaminants is more susceptible to thickening, acting almost like a sludge that exacerbates the problem.
