What are the characteristics of Castrol engine oil?

Castrol-EDGE: The notable feature of Castrol EDGE is its ability to reduce friction between mechanical components, enhancing power while also lowering fuel consumption. Introduction to Castrol EDGE: Castrol EDGE fully synthetic engine oil, inheriting Castrol's century-long experience in lubricant manufacturing, is specifically designed for car enthusiasts. EDGE is a premium car engine oil that ensures exceptional engine performance even under harsh conditions. Choosing engine oil: The engine oil grade essentially represents the oil's viscosity, which can be divided into low-temperature viscosity and high-temperature viscosity. Low-temperature viscosity affects the engine's starting capability in cold conditions, while high-temperature viscosity influences the protection of engine components during operation. The oil grade is demarcated by the letter W; the number before W indicates low-temperature viscosity, and the number after W represents high-temperature viscosity. A smaller number before W means better viscosity at low temperatures, enhancing the engine's cold-start capability. A larger number after W indicates higher viscosity at 100 degrees Celsius, forming a thicker oil film on components. However, higher high-temperature viscosity isn't always better, as increased viscosity can raise the resistance to component movement. The choice should be based on actual conditions.
What I value most about Castrol's engine oil is its Magnetic Protection technology, which provides exceptional protection during cold starts on winter mornings. With conventional oils, I always felt the engine suffered from dry friction during cold starts, but after switching to the Magnetic series, it's noticeably quieter and smoother. Their oil film has strong adhesion, forming a protective layer on component surfaces even after shutdown—especially friendly for those who frequently take short trips. The cleaning performance is also impressive, with minimal sludge after 8,000 kilometers. However, its shear resistance under high-temperature conditions is slightly weaker compared to top-tier racing oils. It's entirely sufficient for regular family cars, but for modified vehicles on tracks, I'd recommend opting for the track-specific version.
