The Castrol EDGE range is designed to unlock true engine performance when you need it most.
Today’s engines are at the cutting-edge of technology and engineering – they are smaller and ultra-efficient. These advanced engines challenge the oil with increased pressures which can cause friction.
Castrol EDGE with Fluid TITANIUM physically transforms its structure – becoming stiffer at points of extreme pressure, keeping metal apart and reducing friction. When the pressure subsides, the oil reverts to its free-flowing state. Stronger under pressure, Castrol EDGE with Fluid TITANIUM transforms its structure and reduces performance-robbing friction by 20%*.
Castrol EDGE 5W-30 A3/B4 is an advanced full synthetic SAE 5W-30 engine oil. It is boosted with TITANIUM Fluid Strength Technology™ to give you the confidence to demand maximum engine performance from today's highly tuned four cylinder and latest technology engines, operating with tighter tolerances, requiring lower viscosity and stronger oils for variable service intervals.
Discover why your engine oil needs to be strong.
Castrol EDGE 5W-30 A3/B4 should be used in engines where maximum efficiency and protection is demanded. Castrol EDGE 5W-30 A3/B4 is suitable for use in automotive gasoline or diesel engines* where the manufacturer recommends an ACEA A3/B4, API SL/CF or earlier specification 5W-30 lubricant. Approved by leading automobile manufacturers.

Advances in engine technology have led to increased power and efficiency, meaning engines work harder and under higher pressures than ever before.
The only thing keeping metal engine components apart is the oil, so it needs to be strong and remain strong.
Castrol EDGE is our strongest and most advanced range of engine oils. Its TITANIUM FST™ doubles its film strength preventing oil film breakdown and reducing friction.
Castrol EDGE with TITANIUM FST™: helping your engine perform at its best.
