This means a synthetic 5W-30 will maintain its protective viscosity closer to its rated value for a longer period of time compared to a conventional oil. The second number in the viscosity rating indicates the oil’s thickness at 100°C.
Understanding Base Oil Stock Viscosity Properties and Performance
The number preceding the 'W' indicates cold-temperature performance, while the number following it reflects viscosity at high operating temperatures. Modern engines are precision instruments engineered to work with specific oil weights.
Driving Conditions and Climate Considerations Geographic location and driving habits play a significant role in viscosity selection. The Science Behind the Flow Engine oil viscosity is manipulated through the base oil stock and a complex additive package known as viscosity modifiers.
Understanding Base Oil Stock Viscosity Properties
Lower numbers signify thinner oil that circulates quickly, whereas higher numbers denote thicker oil designed for greater load-bearing capacity. High-Temperature Performance and Stability While cold flow is essential, high-temperature stability is equally important.
