the way oil behaves under extreme pressures. It helps to form shock-absorbing pads that prevent damage from metalto-metal contact.

The oil is Castrol’s answer to car manufacturers’ downsizing, turbocharging and advanced engine designs like direct fuel injection and variable valve timing. This has resulted in engine pressures almost doubling, causing greater stress on the oil, equivalent
