In this context, the "5" in both grades means the oil flows well at low temperatures, typically offering reliable cold starts down to about -30°C or -22°F. This number represents the oil's kinematic viscosity at 100°C, measured in centistokes (cSt).
Long Term Engine Wear: 5W20 vs 5W30 Oil Performance Under the Hood
Understanding the difference between 5W-20 and 5W-30 oil is essential for ensuring optimal engine protection, fuel efficiency, and longevity. Cold Weather: Both grades perform identically in cold conditions due to the shared "5W" rating.
This thicker film is crucial for protecting engines that operate under heavier loads or higher revolutions per minute (RPM), where the risk of metal-to-metal contact is greater. The number before the "W" indicates cold-temperature performance, while the number after signifies the oil's thickness at operating temperature.
