Understanding Viscosity and Its Importance
Viscosity is a measure of a fluid’s resistance to flow. In motor oil, viscosity affects how well the oil lubricates engine parts, especially during cold starts. The “5W” in 5W-20 indicates its performance in cold temperatures, while “20” represents its viscosity at operating temperatures. This balance makes 5W-20 suitable for most moderate climate conditions.
Benefits of 5W-20 Motor Oil
Using 5W-20 motor oil provides several advantages:
- Enhanced Engine Protection: Its formulation offers excellent protection against wear and tear, extending engine life.
