Is an Engine Oil Temperature of 120°C Normal?
2 Answers
If the engine oil temperature reaches 120°C on a highway, it is normal. However, if the oil temperature remains at 120°C for an extended period in urban driving conditions, it is abnormal. Below is relevant information about Volkswagen engine oil temperature: 1. The normal operating temperature range for Volkswagen engine oil is generally between 70°C and 90°C; 2. During highway driving or aggressive driving, the oil temperature will inevitably rise, reaching around 100°C to 120°C; 3. If the oil temperature consistently stays at 120°C in urban driving conditions, and the oil warning light is illuminated, it is definitely abnormal. This likely indicates an issue that requires immediate attention and troubleshooting.
I've been driving for over a decade and have seen my share of oil temperature issues. 120°C is indeed on the high side, but it's not yet a major problem. Normally, engine oil should maintain a temperature between 90°C to 110°C during operation. Exceeding 115°C becomes concerning, especially during highway driving or in traffic jams. Such temperatures can cause oil thinning, insufficient engine lubrication, and even damage to seals. Common causes include low coolant levels, faulty cooling fans, or inefficient water pumps. This issue becomes more prevalent during hot summers. I recommend checking your cooling system and fans promptly, and verifying your oil level is adequate. Brief spikes to 120°C are tolerable, but if the high temperature persists or is accompanied by unusual smells or noises, get it professionally checked immediately. In daily driving, avoid aggressive acceleration to reduce engine load, which helps maintain lower temperatures.
