1 Answers
Engine oil SAE 10W-30 is referred to as a "multi-grade" oil. The smaller the number in SAE 10W (such as 10 in this example), the less likely the oil is to become viscous at low temperatures. Here is an introduction to engine oil: Introduction to engine oil: Engine oil, also known as engine lubricating oil, is called Engine-oil in English. It has a density of approximately 0.91×10 (kg/m³) and serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is hailed as the "blood" of a car. Composition of engine oil: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil's performance, imparting certain new properties, making them an important part of lubricating oil.
