Should You Take the Leftover Engine Oil After Car Maintenance?
1 Answers
You can take it away, but it must be stored properly. Here is some information about engine oil: 1. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives are an important part of the lubricating oil. 2. Types of Engine Oil: The SAE viscosity classification for winter oils includes grades such as 0W, 5W, 10W, and 15W. 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, and 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature.
