An advanced, heavy-duty oil designed for high speed, four-stroke diesel engines, Castrol RX Super 15W-40 CJ-4/E9 20L is designed to offer previously unimagined protection against wear.

Carefully formulated to protect engines against abrasive wear - one of the major causes of damage in modern engines — Castrol RX Super engine oil boasts a multi-functional approach to keeping your engine functioning at peak performance levels. Firstly, the DuraShield Boosters prevent large particles of soot from agglomerating, which protects surfaces within your engine from wear. And secondly, the DuraShield provides a protective layer on the moving metal surfaces within your engine, providing reliable protection under even challenging conditions.

Castrol RX Super 15W-40 CJ-4/E9 works across a wide range of fuel qualities, compatible with engines fitted with EGR and the latest exhaust-after-treatment systems such as DPF, DOC, and SCR. Its broad, versatile compatibility means that you can use Castrol RX Super in a huge range of vehicles including trucks, tractor, LCVs, off-highway equipment, agricultural and fixed plant machinery.
