SAE on oil stands for Society of Automotive Engineers. This organization has developed a numerical code system to grade motor oils according to their viscosity characteristics. SAE viscosity rating refers to the oil's thickness and ability to flow at certain temperatures. For example, SAE 30 oil has a specific viscosity, making it suitable for certain engine types and conditions. Understanding the SAE rating helps in selecting the right oil for your vehicle, ensuring optimal performance and longevity.
