Diesel engines are tough on oils, tending to have increased soot built-up, leading to sludge formation that can restrict drain intervals.

        Castrol’s GTX Diesel is suitable in both petrol and diesel engines. Castrol GTX Diesel viscosity is specifically designed for these conditions.

     It also has a higher alkalinity,reducing acid formation and reducing corrosion and wear in diesel engines.
