What is the boiling point of engine oil?
1 Answers
Typically, the boiling point of engine oil is around 150 degrees Celsius, but the exact boiling point varies by brand and requires actual testing to obtain an accurate value. In addition to the boiling point, other parameters of engine oil are as follows: Definition and significance of engine oil flash point: The lowest temperature at which an oil product can produce a flash when exposed to a flame under test conditions is called the flash point. It refers to the temperature at which the oil begins to flash when exposed to a flame during a test where the temperature is continuously increased. Depending on the testing method, the flash point of oil can be classified into open-cup and closed-cup flash points. The flash point of engine oil is an indicator of its volatility. The lighter the oil fraction, the higher its volatility, and the lower its flash point. Conversely, the heavier the oil fraction, the lower its volatility, and the higher its flash point. Additionally, the flash point is an indicator of the fire hazard of petroleum products. Definition and significance of engine oil pour point: The pour point of engine oil refers to the highest temperature at which the surface of the oil sample stops moving when cooled under specified test conditions. It is a conventional indicator used to measure the low-temperature fluidity of lubricating oils. A higher pour point indicates poorer low-temperature fluidity of the oil. Definition and significance of engine oil ash content: The solid residue left after burning an oil sample under specified conditions is called sulfate ash, expressed as a percentage. A higher number indicates that the engine oil may be more prone to sludge formation.
