What is Castrol BP3000 engine oil?

[SanDaisy]

Castrol BP3000 is a semi-synthetic engine oil. The following is an introduction to engine oil knowledge: 1. Introduction: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks in the engine. It is hailed as the 'blood' of automobiles. Engine oil consists of two components: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil, imparting certain new characteristics, making them an essential part of lubricating oil. 2. Requirements: As a type of machinery, engines have common requirements for lubricating oil similar to general machinery, such as appropriate viscosity, certain anti-oxidation, anti-wear, anti-corrosion, and viscosity-temperature properties. However, engines are also a special type of machinery, and their requirements for lubricating oil have unique aspects.
