Is a Volkswagen engine oil temperature of 100 degrees Celsius normal?
1 Answers
An engine oil temperature of 100 degrees Celsius is normal for Volkswagen vehicles. Normal operating temperature range for engine oil: The normal operating temperature for engine oil is around 100 degrees Celsius. During regular speed driving, the cooling effect of the coolant reduces the oil temperature to approximately 80-90 degrees Celsius. However, at low speeds, the cooling effect diminishes, causing the oil temperature to rise slightly (to around 100 degrees Celsius). Functions of engine oil: Engine oil forms a lubricating film that converts dry metal friction into liquid friction between oil layers, reducing frictional resistance and minimizing component wear. Additionally, engine oil serves functions such as cooling, cleaning, sealing, rust prevention, and absorbing impact loads.
