At What Temperature Should Winter Engine Oil Be Changed?

[DiHarmony]

Winter engine oil should be changed when the temperature is around 20 degrees Celsius. Precautions for changing winter engine oil are as follows: Choose the appropriate engine oil: In winter, as the temperature drops, the viscosity of the engine oil increases, making it harder to flow and thus increasing engine resistance. If you experience difficulty starting the engine, check whether the oil grade used is incorrect. Check the antifreeze: To prevent the antifreeze from freezing due to low winter temperatures, which could cause damage, car owners in colder regions should replace it with a coolant that has a lower freezing point. The freezing point should be at least 20 degrees Celsius below the lowest temperature in the area to ensure safety. Otherwise, a cold front from Siberia could potentially damage the car's radiator or even the engine block.
