What does SAE stand for in relation to oil viscosity ratings?

SAE stands for the Society of Automotive Engineers, which is an organization that develops standards for various automotive and aerospace industries, including oil viscosity ratings. The SAE assigns viscosity grades to engine oils based on their performance characteristics at different temperatures. These ratings are important because they help consumers understand the appropriate oils for their vehicles, ensuring proper engine lubrication and performance.

The grade system, such as SAE 10W-30, indicates how the oil behaves at low and high temperatures, facilitating better engine care and operation. Understanding these standards helps in selecting the right type of oil for different engines and environmental conditions. The other options, while potentially viable-sounding names for engineering organizations, do not represent established standards or bodies involved in oil viscosity ratings.
