The number after the dash represents the oil's viscosity at the normal operating temperature of 100°C (212°F), where a higher number signifies a thicker, more durable lubricant film. The term " sae meaning in oil " refers to the Society of Automotive Engineers grading system, which classifies oils based on their viscosity, or thickness, at various temperatures.
Decoding SAE Oil Grade Meaning and Viscosity Insights
They provide the necessary cold-flow properties of a low-grade oil while maintaining the protective qualities of a high-grade oil once the engine reaches operating temperature. This standardized scale ensures that the lubricant performs optimally within the specific climate and mechanical demands of an engine.
Multi-Grade Technology Modern lubricant technology has largely solved the dilemma of seasonal oil changes through multi-grade formulations. Using an oil that is too thick for a high-tech, fuel-efficient engine can trigger warning lights and reduce power, while using oil that is too thin can lead to excessive metal wear and catastrophic engine failure over time.

These recommendations are based on rigorous engine testing designed to balance longevity, efficiency, and performance. A lower number like 0W or 5W means the oil flows more easily when the engine is cold, reducing wear during startup.
