What type of engine oil is suitable for the Civic?
2 Answers
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.
I've been driving a Civic for many years and found that using the right engine oil is crucial. My car is a 2018 model, and the manual recommends using 0W-20 synthetic oil. I've tried several brands, and Mobil's AFE series works great—after switching, the engine runs super smoothly, starts quicker, and even saves a bit on fuel costs. If you use the wrong oil, like a higher viscosity such as 10W-40, cold starts in winter can be difficult, the engine noise increases, and over time, it accelerates wear. I change the oil every 5,000 to 8,000 kilometers—don't delay too long, as it can extend the engine's lifespan by at least a few years. When choosing oil, don't just look at the price; make sure it matches your car's model and year. Otherwise, engine repairs can be troublesome and costly.
