Castrol EDGE Professional A3 0w-40


Fluid TITANIUM - Stronger Under Pressure


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 Professional is micro-filtered and certified CO2 Neutral according to the highest global standard*. Its
patented Fluid TITANIUM transforms to be stronger under pressure and reduces friction for maximum engine
performance when you need it most.
