What type of engine oil is suitable for the Civic?

[DelJackson]

Civic uses 0W20 full synthetic engine oil. The meaning of 0W20 and the functions of engine oil are as follows: Meaning of 0W20: 0 represents the viscosity of the engine oil, with 0 being the smallest, indicating that the oil has lower viscosity at low temperatures and better fluidity. W stands for winter-grade engine oil. 20 is the oil viscosity, with 20 representing lower viscosity, suitable for low-temperature use. The higher the number, the higher the operating temperature it can handle. The choice of engine oil should be based on the operating temperature of the vehicle. Functions of engine oil: Engine oil lubricates and reduces friction in the engine, assists in cooling, provides sealing to prevent leaks, prevents rust and corrosion, and acts as a shock absorber. It is often referred to as the "blood" of a car. The engine is the heart of the car, containing many metal surfaces that move against each other at high speeds under harsh conditions, with operating temperatures reaching 400 to 600 degrees Celsius. In such extreme conditions, only qualified lubricating oil can reduce wear on engine components and extend their service life.
