Castrol EDGE Synthetic 5W-30 Engine Oil A3/B4 1L
Castrol EDGE 5W-30 engine oil 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 5W-30 A3/B4 is an advanced full synthetic engine oil suitable for use in automotive petrol and diesel vehicles, where the manufacturer recommends an ACEA A3/B4, API SL/CF or earlier specification 5W-30 engine oil.
