Castrol EDGE is proud to drive the pioneering spirit of Castrol, challenging the technical frontiers of strength to maximize performance.

Castrol EDGE delivers strength for advanced power and protection.


Castrol EDGE is the oil of choice for many leading car manufacturers and a trusted technical partner of some of the world’s most demanding motorsport teams.



Castrol EDGE delivers:

  • Performance: Superior performance for the oil change interval recommended in your owner’s manual or by your oil
  • Power: Fights 42% more power robbing deposits***
  • Protection:Superior engine protection versus conventional and synthetic blend oils****
*Based on the ASTM HFRR Friction Test
**Tested in 5W-30 versus all major conventional brands in Kurt Orbahn Test
*** Compared with industry IIIG WPD (high temperature deposit) requirements. 
**** Based on ACEA A/B specification. Castrol EDGE 5W-30 meets Europe’s ACEA A/B specification while Pennzoil Platinum 5W-30 and Valvoline Synpower 5W-30 do not.

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

A new oil technology from Castrol, Fluid Titanium Technology, doubles the strength of Castrol EDGE.* It’s now three times stronger against viscosity breakdown than conventional oil (Mobil 1 EP).**  The unique titanium technology physically changes the way oil behaves under extreme pressures.  In industry standard tests, Castrol EDGE with Fluid Titanium has doubled its film strength, preventing oil from breaking down and reducing friction to maximize engine performance.



Engine oils need to be able to constantly respond to the ever-changing environments in your engine. Every second of the drive your engine oil needs to be able to react to the needs of different metal-to-metal contact points in your engine each with different demands, pressures and temperatures. Castrol EDGE Extended Performance with Titanium FST provides unsurpassed protection for critical engine parts, ensuring optimal performance – with the strength to enable an extended drain interval of up to 15,000 miles. Independent testing has proven EDGE Extended Performance stronger than Mobil 1 Extended Performance against viscosity breakdown – the ultimate test of strength.*

Castrol EDGE Extended Performance with Titanium FST features the latest of Castrol technology:

  • Performance: The strength to perform for 15,000 miles between oil changes - Guaranteed **
  • Power: The muscle to maintain viscosity stability under the extreme force of your engine
  • Protection: Proprietary titanium additive provides unsurpassed wear protection
* Castrol EDGE Extended Performance 5W-30 was proven stronger against viscosity breakdown based on ASTM 6278 and CEC-L-14 independent testing 
** If your vehicle is under warranty, follow the oil change interval recommended by your manufacturer. Extended service is not recommended in severe service applications such as racing, frequent towing or hauling, commercial use, extremely dirty/dusty conditions or excessive idling.
