Selecting an oil with a pour point lower than the expected ambient temperature is critical for cold-weather reliability. Additives known as pour point depressants are included in modern formulations to inhibit wax crystal formation and maintain fluidity.
Cold Weather Oil Selection: Choosing the Right Grade for Winter Conditions
How Motor Oil Behaves in Cold Temperatures Motor oil does not freeze in the same way water turns to ice at 32°F (0°C). As a result, synthetic options typically outperform conventional alternatives in severe winter conditions, offering faster lubrication and reduced wear during startup.
Matching this recommendation to the climate in which you drive ensures dependable starts and long-term protection. Instead, as temperatures drop, the thickening of oil occurs due to changes in its viscosity.
Cold Weather Oil Selection: Choosing the Right Grade for Winter Conditions
In freezing conditions, some additives can become less effective if the oil thickens excessively or remains stagnant in the oil pan. Manufacturers specify this metric to help drivers choose an appropriate grade for their climate.
