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 now with Fluid Titanium Technology 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 Technology 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
