This sequence is far more than a random assortment of numbers; it is a standardized measurement that communicates the oil's performance characteristics. Summer Grades The number preceding the "W" indicates the oil's viscosity during cold conditions.
Understanding SAE Oil Ratings and Temperature Performance
This dual-number format defines the classification of multi-grade oils, which are designed to work efficiently year-round. Using an oil that is too thick can lead to poor fuel economy and difficulty starting the engine, while using one that is too thin can result in inadequate lubrication and accelerated wear.
An oil with a high viscosity flows slowly and resembles syrup, while a low viscosity oil flows quickly and resembles water. These oils utilize additives called viscosity index improvers to adjust their flow properties.
Understanding SAE Oil Ratings and Temperature Performance
The testing procedure involves measuring the time it takes for a standardized amount of oil to flow through a calibrated tube at designated temperatures. Specifically, the "SAE" designation within that code refers to the Society of Automotive Engineers, the organization that established the uniform grading system used globally.
