Is an engine oil temperature of 105 degrees Celsius normal for a Volkswagen?
2 Answers
The normal operating temperature range for engine oil is generally between 70-90 degrees Celsius. If the vehicle is driven at relatively high speeds, the temperature may exceed 100 degrees, typically ranging between 100-110 degrees. There's no need to be overly concerned if the oil temperature is slightly higher, as it depends on the specific circumstances. Specific circumstances: If the vehicle consistently operates above 100 degrees during normal driving or exceeds 120 degrees during prolonged high-speed driving, there may be an issue with the vehicle. If we're discussing coolant temperature, 105 degrees is somewhat high. Generally, the normal coolant temperature for a vehicle is around 90 degrees. If the temperature exceeds 100 degrees, it's necessary to inspect the vehicle. Possible causes: Engine oil consumption: This is a common factor that can lead to higher engine oil temperatures. In such cases, the vehicle should be stopped for a while to check if the oil temperature gauge shows a lower reading, and then calculate oil consumption based on the last maintenance interval. Additionally, if the oil hasn't been changed or maintained for an extended period, the cooling and lubricating properties of the old oil deteriorate, which can also cause excessive oil temperatures. Therefore, if the oil hasn't been changed for a long time, it should be replaced promptly to see if this resolves the issue.
I've been driving a Volkswagen for many years and often pay attention to the oil temperature display. 105 degrees is considered normal but slightly on the higher side, especially during high-speed driving or hot summer days. Volkswagen engines are designed to handle high-temperature conditions, with normal operating temperatures typically ranging between 90 and 110 degrees. If it occasionally reaches 105 degrees, don't panic—the engine can regulate itself. However, it's important to check if the cooling system is functioning properly, such as whether the radiator fan can start automatically and if the radiator is clean. Prolonged high temperatures can accelerate oil aging and shorten the oil change interval, so I prefer using full synthetic oil to enhance high-temperature resistance. After parking, if the engine hood doesn't feel too hot to the touch, it's generally fine. Remember, as long as the temperature remains stable without sudden spikes, it's safe. If it frequently exceeds 105 degrees, it's time to visit the repair shop. In short, as a car owner, developing a habit of regular maintenance is the most worry-free approach.
