Castrol EDGE

Modern engines are smaller and more efficient, without sacrificing performance. The intense pressures in today’s engines cause friction, which can waste up to 10% of engine performance. For today’s drivers, losing engine performance is simply not an option.

Castrol EDGE with Fluid TITANIUM is our most advanced engine oil.  It transforms to be stronger under pressure and reduces performance-robbing friction to unlock the true performance of your engine.

Castrol EDGE FTT


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
Available in viscosities: 0W-20, 0W-30, 0W-40, 5W-20 and 5W-30
