Castrol RX Super 15W-40 CJ-4/E9 is a cutting-edge, heavy-duty diesel engine oil designed to provide superior protection in a wide range of diesel engines. It is suitable for use in high-speed 4-stroke diesel engines that operate with various fuel qualities. Additionally, it is compatible with diesel engines equipped with EGR and the latest exhaust after-treatment systems, such as DPF, DOC, and/or SCR.

The oil features DuraShield Technology, which offers up to 40% better wear protection compared to traditional oils. It provides a dual layer of protection by preventing the agglomeration of soot particles and forming a protective layer on metal surfaces, thus reducing engine wear under severe operating conditions. Castrol RX Super 15W-40 CJ-4/E9 is perfect for use in naturally aspirated and turbocharged diesel engines, found in trucks, agricultural machinery, buses, and off-highway equipment.
