Stronger Under Pressure. Proven Where It Matters.
Modern engines operate under extreme pressure, creating intense friction that can rob performance and accelerate wear. That's why Castrol EDGE 5W-40 is engineered with Titanium Fluid Strength Technology (FST).
Titanium FST transforms under pressure, strengthening the oil film to keep critical engine components separated, reducing friction and helping unlock maximum engine performance when you need it most. It is designed to maintain protection, performance, and responsiveness even under demanding driving conditions.
