Lubricating oil and engine oil

In the world of automobiles, although lubricating oil and engine oil both belong to the large family of lubricants, they are not interchangeable at will. The broad applicability of lubricating oil should not be equated with its ability to replace engine oil. In fact, engine oil is specifically designed for engines, with distinct types for gasoline and diesel engines, much like keys matching locks—each one precisely tailored.

Lubricating oil is widely used in automobiles and mechanical equipment, providing essential lubrication and protection through the skillful blending of base oils and various additives. It plays an indispensable role in reducing friction and extending service life.

Engine oil, especially motor oil, is meticulously designed with key components such as anti-wear agents, detergents, dispersants, and viscosity index improvers. Its goal is to ensure smooth operation inside the engine, reduce component wear, and remove deposits, thereby maintaining the engine's efficient performance.

In general, although lubricating oil and engine oil overlap in function, they have fundamental differences in design and application. Therefore, replacing engine oil with lubricating oil is not feasible. The correct choice is to select the most suitable lubricating product based on the vehicle manufacturer's recommendations and the type of engine oil.
