Greases are preferable in cases where oils cannot be used because grease stays in place, forming a 'protective shield'. There are many different technologies available for use under different circumstances. Often trucks (off road vehicles) can be subject to a challenging environment such as a heavy load, dirt and water where critical parts can only be protected by a grease layer.
Castrol’s choice of greases range from multipurpose to the special greases with Castrol technology providing outstanding protection and longer component life under demanding conditions and keeping your vehicle in operation longer.
