Castrol Edge 5W-30 LL - 4 Litres : Today’s engines are smaller and more efficient, without sacrificing performance. These advances in engine design challenge the oil with increased pressure. To withstand this, oils need to be stronger than ever before During every engine revolution, intense friction hotspots occur. Flashing into existence for a matter of micro-seconds, they continually move around the engine as it delivers power. Collectively, these friction hotspots can waste up to 10% of engine performance. Under such pressures, the only thing standing between metal surfaces is the oil. That's why your oil needs to be strong and stay strong. Castrol EDGE 5W-30 LL 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. Features: • Advanced full synthetic for gasoline/petrol and diesel engines • Boosted with titanium FST • Sustains maximum performance even
