An oil temperature of 97 degrees is normal. The normal operating temperature of engine oil is generally between 70 to 90 degrees Celsius, with some localized areas being slightly higher, but it typically does not exceed the coolant temperature. Effects of excessively high oil temperature: It can impact certain components of the vehicle, especially those far from the radiator or with weaker structures. Prolonged exposure to high temperatures can easily cause damage or even complete failure. It also affects the viscosity of the oil, leading to severe wear on some engine parts (due to oil film breakdown), and in extreme cases, can cause cylinder scoring or bearing seizure. How to check oil temperature: If the vehicle has an oil temperature sensor, you can use a diagnostic scanner to read the data. If not, you can only estimate it indirectly through the coolant temperature.

I've been driving for over a decade and have some insights about various cars. Oil temperature at 97°C? Quite normal, usually fluctuates between 90 to 100 degrees. During my long-distance drives, the temperature often stays around 95°C, especially in summer with AC on or during highway driving - 98°C isn't unusual. This is the operating temperature engines need - higher temps help burn off impurities in oil, but exceeding 105°C may thin the oil and reduce lubrication. If it's stable at 97°C, no need to worry; significant fluctuations are what deserve attention. My old car once showed 99°C, which turned out to be low coolant. Developing the habit of monitoring gauges while checking oil quality and cooling system can prevent minor issues from escalating. Proper temperature control ultimately extends engine life and improves fuel efficiency.
