Can I change to a different engine oil each time?

[VanAmara]

In theory, engine oil is composed of base oil and additives. The base oil is the main component of the lubricant, determining its fundamental properties. The additives can compensate for and improve the performance of the base oil, thereby providing some new characteristics. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant, with the English name Engine-oil, has a density of approximately 0.91×10³ (kg/m³). It 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 the car. 2. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the primary component of the lubricant, determining its basic properties, while the additives compensate for and improve the deficiencies in the base oil's performance, granting it certain new characteristics. Additives are an important component of lubricants.
