Hot Weather Stability: 5W-30 maintains its viscosity better in extreme heat, reducing the risk of thinning. A 5W-20 oil is designed to be low-drag, reducing the energy the engine needs to pump the oil through its passages.
5W20 vs 5W30 Fuel Efficiency: How Viscosity Impacts MPG
Protection The performance characteristics of 5W-20 and 5W-30 cater to different driving priorities. This number represents the oil's kinematic viscosity at 100°C, measured in centistokes (cSt).
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. Manufacturer Specifications and Modern Engine Design.
