This measurement determines how resistant the oil is to flow when subjected to extreme cold. High-performance driving, characterized by frequent high-RPM operation, often necessitates a thicker oil to maintain film strength under extreme stress.
How Multi Grade Oil Flow Behavior Analysis Explains Viscosity Ratings and Performance
Because they are engineered molecules, synthetics exhibit less thermal breakdown and shear thinning than their mineral-based counterparts. This heat resistance is achieved through the careful calibration of viscosity index improvers.
The second number in the viscosity rating indicates the oil’s thickness at 100°C. Understanding engine oil viscosity is fundamental to responsible vehicle ownership.

These codes, often seen as sequences like 5W-30 or 10W-40, provide a standardized measure of flow characteristics. Lower numbers signify thinner oil that circulates quickly, whereas higher numbers denote thicker oil designed for greater load-bearing capacity.
