Castrol EDGE Euro Car fluids are engineered with Fluid TITANIUM Technology to transform under pressure, increasing its film strength to prevent oil breakdown, reduce friction and have been optimized to deliver up to 40% better performance* against ACEA standards to unlock maximum engine performance.
Castrol EDGE Euro Car product range has been optimized to meet the stringent requirements of the various European Automobile Manufacturers Association or ACEA oil sequences. These standards can apply to both gasoline and diesel powered engines and are often more demanding than ILSAC/API requirements.
