Pour Point and Cold Flow Properties The pour point of an oil is the lowest temperature at which it will still flow. Consider using a block heater if temperatures regularly drop below -20°C (-5°F).

If this happens, the oil filter may clog, and the engine will be starved of lubrication, leading to severe damage upon startup, even if the oil ultimately returns to a liquid state as the engine warms. However, if the temperature drops significantly below the oil's designed threshold, the wax content can begin to crystallize.
Use high-quality synthetic oils, as they generally handle temperature fluctuations better than conventional oils. They have a more uniform molecular structure, which means they are less likely to wax or gel in the cold.
Can Oil Freeze Storage Guidelines Winter
Best Practices for Cold Weather Maintenance While pure crude oil can freeze, refined motor oil contains pour point depressants to inhibit this. However, if the temperature drops significantly below the oil's designed threshold, the wax content can begin to crystallize.
