The number following the "w" represents the oil's viscosity at high operating temperatures, specifically 212°F (100°C). While both share the same high-temperature viscosity rating of 20, their cold-flow properties differ significantly, leading to distinct behaviors in various temperatures.

Consequently, many manufacturers recommend 0W-20 specifically to meet stringent emissions and fuel economy standards without compromising engine protection. This high-temperature consistency ensures adequate lubrication and protection against wear during standard driving conditions.
A 0W oil flows more readily at extremely low temperatures, often as cold as -40°F or -40°C, making it significantly easier for the engine to turn over during harsh winters. Evaluating your local temperature extremes is a key step in selecting the right oil for your needs.
