SAE 30 refers to a specific viscosity grade of engine oil as defined by the Society of Automotive Engineers (SAE). The "30" indicates that the oil has a certain viscosity at 100 degrees Celsius, making it suitable for warmer temperatures. Unlike multi-grade oils, which contain additives to perform well in both high and low temperatures, SAE 30 is a single-grade oil, meaning it performs optimally at a designated temperature range. It's often used in small engines and older vehicles that require a non-multi-grade oil.
