Castrol EDGE 0W-40 A3/B4 is a high performance fully synthetic engine oil for modern, higher revving sports, performance and luxury vehicles requiring lower viscosity, higher performance oils. Castrol EDGE with Fluid Strength Technology™ is Castrol’s strongest and most advanced range of engine oils. Its unique adaptive strength reduces metal to metal contact across a range of different driving speeds.
The latest Castrol Edge engine oils feature what Castrol call "Fluid Strength Technology™". Castrol say that Fluid Strength Technology is a new dynamic system that actively strengthens the oil, continuously responding and adapting to your engine's every need even under the severest possible pressures.
Tailor-made to the specific requirements of a range of engines, it is designed to minimise metal to metal contact, constantly adapt across a variety of engine speeds and driving conditions, and remain stronger for longer, giving you always the confidence to drive how you want, when you want.
Castrol Edge 0w-40 A3/B4 supercedes Castrol Edge Sport 0w-40 which has been discontinued.
