Today's engines are breaking new ground in both technology and technical development: they are smaller and ultra-efficient. These advanced engines test the oil at higher pressures, which can cause friction. Castrol Edge 5W30 Long Life with Fluid Titanium physically changes its structure and becomes stiffer at extreme pressure points. This prevents metal-to-metal contact and reduces friction. When the pressure decreases, the oil returns to its liquid state. Castrol EDGE with Fluid Titanium is stronger under pressure, changes structure and reduces performance-degrading friction by 20%.
