What is the normal temperature for diesel engine oil?

[Kylie]

Oil temperature of 100 degrees is normal, and the operating temperature of engine oil is generally between 70 degrees and 90 degrees. The following is a related introduction to automotive engine oil: Functions of engine oil: Alleviate friction and high temperatures, reduce gas leakage, prevent external pollutants, prevent contact between water, air, acidic harmful gases and parts, buffer the pressure rise at the engine cylinder port, and flush away dirt generated on the working surfaces of parts. Introduction to engine oil: Engine oil, also known as engine lubricant, serves functions such as lubrication and wear reduction, auxiliary cooling and temperature reduction, sealing and leakage prevention, rust and corrosion prevention, and shock absorption and buffering for the engine. It is hailed as the 'blood' of automobiles. Engine oil consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, determining the basic properties of the lubricating oil, while additives can compensate for and improve the shortcomings of the base oil's performance, endowing it with certain new properties, making them an important component of lubricating oil.
