Castrol RX Super 15W-40 CJ-4/E9 is an advanced, high-performance diesel engine oil designed for modern, high-speed 4-stroke diesel engines. With DuraShield Technology, this oil delivers 40% better wear protection, effectively addressing abrasive wear in diesel engines under severe operating conditions. It prevents soot agglomeration, which can cause metal-to-metal contact and damage, while providing a protective layer that resists breakdown even under tough conditions. Castrol RX Suoer 15W-40 is compatible with engines fitted with Exhaust Gas Recirculation (EGR) systems and the latest exhaust after-treatment systems such as Diesel Particulate Filters (DPF), Diesel Oxidation Catalysts (DOC), and Selective Catalytic Reduction (SCR). Suitable for use in trucks, buses, agricultural machinery, off-highway equipment, and other diesel-powered vehicles.
