Is Engine Oil Really Thin?

[LolaLee]

If it is thin, it is difficult to determine whether it is fake oil. Here is an introduction to engine oil knowledge: Introduction: Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the "blood" of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Additives are a crucial part of the lubricant. Requirements: As a type of machinery, engines share common requirements for lubricants with general machinery, such as appropriate viscosity, oxidation resistance, wear resistance, corrosion protection, and viscosity-temperature performance. However, engines are also unique machinery, and their requirements for lubricants have special aspects.
