STRENGTH FOR MAXIMUM PERFORMANCE
Technological advancements have allowed today’s engines to become smaller, yet more powerful and efficient.  The need for engines to deliver increased fuel economy, reduced emissions and high performance means they must work harder than ever before.  Engines produce pressures of up to 10 tons per square centimeter. That's like five cars resting on a high heel. More pressure means more stress for the oil, more metal-to-metal contact and friction that can rob performance from your engine.

CASTROL EDGE IS NOW TITANIUM STRONG
Castrol EDGE  is three times stronger against viscosity breakdown than the leading synthetic and leading conventional oils.**  The unique titanium technology physically changes the way oil behaves under extreme pressures  doubling its film strength*, preventing oil from breaking down and reducing friction to maximize engine performance.

* Castrol EDGE with Fluid Titanium has twice the film strength of our previous formula based on the HFRR friction test.
** Tested in 5W-30 versus all major conventional brands, Mobil1 and Mobil1 Extended Performance in the ASTM D6278 test.

Castrol EDGE is available in the following grades: 0W-20, 5W-20, 5W-30, 5W-30 A3/B4, 5W-30 C3, 5W-40, 5W-40 Turbo Diesel, 5W-50, 10W-30, 10W-40 and 10W-60
