During this critical moment, moving parts are not yet protected, increasing the risk of wear. The number after the dash indicates the oil's thickness at the normal operating temperature of 100°C (212°F); a higher number like 40 or 50 signifies a thicker oil that maintains a strong film to protect engine components under heat and pressure.
Engine Oil Viscosity Chart High Temperature: Understanding 40 and 50 Grades
" Consequences of Ignoring the Chart. Matching Viscosity to Your Vehicle While the science is fascinating, the most critical application of the engine oil viscosity chart is selecting the grade recommended by your vehicle manufacturer.
The number preceding the "W" represents the oil's viscosity at low temperatures; a lower number like 0W or 5W means the oil remains fluid in freezing conditions, ensuring instant lubrication on a cold start. Decoding the Numbers: What the Viscosity Grade Means The numbers on a container of motor oil, such as 5W-30 or 10W-40, are not arbitrary; they are a standardized measurement of its viscosity performance.
Engine Oil Viscosity Chart at High Temperature: Understanding 40 and 50 Grades
Understanding the engine oil viscosity chart is the single most important step in selecting the right lubricant for your vehicle. Most modern gasoline engines perform optimally with a 5W-20 or 5W-30 viscosity.
