Castrol EDGE 5W-40 A3/B4 with Fluid TITANIUM is the natural choice for drivers who demand maximum engine performance from today’s modern vehicles requiring a high level of protection and higher performance oils.
Today’s engines continually push the boundaries of technology and engineering. They are smaller and ultra-efficient, without sacrificing performance. Advanced engines challenge the oil with increased pressures. These intense pressures cause friction, which can waste up to 10% of an engine’s performance.
Castrol EDGE with patented Fluid TITANIUM transforms its physical structure to be stronger under pressure to keep metal surfaces apart and reduces friction for maximum engine performance when you need it most.
Castrol EDGE 5W-40 A3/B4 is an advanced full synthetic engine oil suitable for use in automotive petrol and diesel vehicles where the manufacturer
recommends ACEA A3/B3, A3/B4 or API SN/CF or earlier specification 5W-40 lubricant.
Castrol EDGE 5W-40 A3/B4 is approved for use in vehicles from leading manufacturers, please refer to the product performance section and your owners handbook.
