What is SAE in Chinese?
1 Answers
SAE is the abbreviation for the English term "Society of Automotive Engineers." Below is an introduction to SAE grades: You may notice markings like SAE40, SAE50, or SAE15W-40, SAE5W-40 on oil cans, which represent the viscosity grades set by the Society of Automotive Engineers. The "W" stands for winter-grade oil, and the smaller the number before it, the lower the ambient temperature it can be used in. The number after the hyphen represents the non-winter grade, and the larger the number, the higher the ambient temperature it can withstand. Oils like SAE40 or SAE50, which have only one set of numbers, are single-grade oils and cannot be used in cold winters. Oils like SAE15W-40 or SAE5W-40, which have two sets of numbers, indicate that they are advanced "multi-grade oils" suitable for a wide range of temperatures, from low to high. Their viscosity values change with temperature to provide comprehensive protection for the engine.
