Viscosity and Temperature Management Viscosity, expressed as a code such as 5W-30 or 0W-20, describes how easily oil flows at different temperatures. Additives called anti-wear agents create a protective layer even before the oil reaches operating temperature, reducing scuffing and extending engine life in stop-and-go traffic or short daily trips.
