AbolishedViscosity classification of internal combustion engine oil
内燃机油粘度分类
Application Summary AI generated
This standard defines the viscosity grades for internal combustion engine oils, such as SAE 0W-20 or 15W-40, based on their flow characteristics at low and high temperatures. It is applied by lubricant manufacturers and automotive engineers in China to classify and label engine oils for gasoline and diesel engines, ensuring proper selection for different operating conditions and climates. The classification aids in quality control and compatibility testing for engine lubrication in vehicles, machinery, and equipment.
