What is the normal oil temperature?
2 Answers
Oil temperature is generally normal between 70°C and 90°C. During aggressive driving, as the engine operates under high load, the temperature can rise to around 100°C to 110°C, making 100°C oil temperature quite normal. However, if the oil temperature consistently exceeds 120°C, it requires immediate inspection to prevent various adverse effects. Consequences of excessively high oil temperature: 1. It can damage certain car components, especially those far from the radiator or with weak structures, leading to long-term damage or even complete failure; 2. It affects the oil's viscosity, causing severe wear on some engine parts (due to oil film breakdown), and in extreme cases, may result in cylinder scoring or bearing seizure.
I've been driving for almost twenty years, and the normal oil temperature generally ranges between 90 to 110 degrees Celsius. In summer, it might rise to 115 degrees when driving on highways, while in winter during cold starts, it could be just over 70 degrees. However, as long as the dashboard shows it within this range, there's no need to worry. If it's too high, say over 120 degrees, the engine might overheat, leading to oil degradation and part damage. If it's too low, like staying around 60 degrees for a long time, it can increase wear and fuel consumption. I suggest keeping an eye on the dashboard regularly. If any warning lights come on, slow down and stop to check—most cars have a specific oil temperature indicator. Developing good habits, like avoiding sudden acceleration or prolonged idling, can help maintain the temperature within a safe range. Using high-quality oil during changes also stabilizes temperature. My old car has always used synthetic oil, and the temperature fluctuations are minimal.
