Using a thicker oil in an engine designed for 5W-20 can lead to delayed lubrication, reduced fuel economy, and potentially increased internal resistance. Maintenance and Change Intervals.
Cold Weather Performance: How 5W-20 Handles Harsh Winters
Cold Weather Performance Drivers in regions with harsh winters often see significant benefits from this viscosity. Because this oil is formulated with a lower viscosity at startup, it reduces the drag on the crankshaft and other internal components.
Conversely, the '20' number indicates the thickness or resistance to flow at 100°C, ensuring the oil maintains a sufficient film strength to protect moving parts under high heat and load. This quick flow is vital because the majority of engine wear occurs during the startup phase, when components are dry and metal-to-metal contact is most likely.
Cold Weather Performance Benefits of 5W-20 Engine Oil
The number preceding the 'W' represents the oil's viscosity at low temperatures, specifically during a cold start. The "5W" indicates its cold-flow properties, while the "20" denotes its viscosity at operating temperature, making it a versatile option for diverse driving conditions.
