Which is more advanced, CK or CL engine oil?
1 Answers
CL engine oil is more advanced. Composition: Engine oil consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, determining the basic properties of the lubricating oil, while additives are an important part of the lubricating oil. Types of engine oil: The SAE viscosity classification for winter oils includes grades such as 0W, 5W, 10W, 15W, etc. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity and the lower the applicable minimum temperature. The SAE viscosity classification for summer oils includes grades such as 20, 30, 40, 50, where the larger the number, the higher the viscosity and the higher the applicable maximum temperature. The SAE viscosity classification for all-season oils includes grades such as 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, etc.
