The number preceding the 'W' indicates the cold-temperature viscosity, while the number following it denotes the viscosity at high operating temperatures. This figure represents the oil’s thickness at the high temperatures generated by combustion, usually measured at 210°F (100°C).
Decoding Synthetic Oil Viscosity Ratings for Optimal Engine Protection
The Consequences of Ignoring the Chart. The Science of Cold Flow Engines experience the most stress during startup, when the metal components are cold and the oil is at its thickest.
Decoding the Numbers: The Meaning Behind the Viscosity Rating The sequence of characters on a bottle of motor oil is a carefully structured code defined by organizations like the Society of Automotive Engineers (SAE). A higher number indicates a thicker, more durable oil that forms a robust lubricating film to prevent metal-to-metal contact under extreme pressure.
Understanding Synthetic Oil Viscosity Ratings and Temperature Performance
Synthetic oils, engineered through chemical synthesis, offer a much more consistent molecular structure, providing superior stability across temperature ranges. Choosing a grade that is too light for a high-performance engine can lead to increased oil consumption and pressure loss, while selecting a grade that is too heavy can reduce fuel economy and hinder the rapid circulation required for effective cooling.
