.

Castrol, a brand synonymous with lubrication excellence, applies advanced engineering to its 5W-20 formulations. This combination of specific viscosity and Castrol’s innovative technology delivers a product designed for modern engine demands. It’s about optimizing performance and protection in various operating conditions.

Decoding the Viscosity Numbers: 5W-20 Explained

The “5W” in 5W-20 stands for “Winter” and indicates the oil’s viscosity at lower temperatures. A lower number here means the oil is thinner in cold weather. This allows for easier engine starting and faster oil circulation upon ignition, reducing wear during those critical first moments.

The “20” refers to the oil’s viscosity at normal operating temperatures. This number represents how thick the oil is when your engine is fully warmed up. A lower number here signifies a thinner oil at operating temperature, which can contribute to better fuel economy by reducing internal engine friction.

Together, 5W-20 means the oil behaves like a 5-weight oil in cold conditions and a 20-weight oil when hot. This multi-grade capability is essential for modern engines that experience a wide range of temperatures. It’s designed to protect your engine efficiently, no matter the climate.
