Castrol RX
Castrol RX is a versatile, multi-purpose, heavy-duty engine oil designed to provide superior protection within diesel engines.
Castrol RX promotes long and healthy engine life, offering protection to diesel engines in a variety of applications and duty cycles. It is engineered to help give long and healthy engine life, giving you peace of mind that your diesel engines are protected in a variety of applications and duty cycles.
Castrol RX's versatility makes it a highly practical solution for heavy-duty workshops and mixed fleets. It conforms to the strict requirements of current engine oil technology and can be used in diesel engines where CJ-4 and below is required. Its special formulation helps to keep the engine cleaner, which provides more reliable engine protection and thus prolongs engine life across different vehicles in your fleet.
- Protection against oil thickening and deposit build-up in critical engine parts
- Protection from wear and deposits.
- Better shear stability and protection against viscosity loss for reliable engine protection.
- Versatile use that enables product rationalization for both workshops and mixed fleets.
The new Castrol RX engine oil range with DuraShield™ Boosters has been upgraded and simplified.

Castrol RX Super 15W-40 CJ-4/E9
Castrol RX Super 15W-40 CJ-4/E9 is an advanced heavy duty diesel engine oil. It is suitable for use in high speed 4-stroke diesel engines that use a broad range of fuel qualities. It is compatible with diesel engines fitted with EGR and the latest exhaust after treatment systems such as; DPF, DOC and/or SCR.
Recommended for use in all naturally aspirated and turbocharged diesel engines fitted in trucks, tractors, buses, LCV’s and off-highway equipment, agricultural and fixed plant machinery.
Features & benefits
New and advanced Castrol RX Super 15W-40 CJ-4/E9 with specially engineered DuraShield™ Boosters delivers 40% better wear protection*.
One of the main causes of damage in modern engines is abrasive wear. Castrol RX Super 15W-40 CJ-4/E9 with DuraShield™ Boosters is proven in industry testing to provide protection to your engine in two ways:
- Under severe engine operating conditions soot can agglomerate to form large particles which displace oil on moving metal surfaces and results in metal to metal contact. DuraShieldTM Boosters helps to prevent the agglomeration of soot as well as protecting surfaces from wear.
- Provides a protective layer on the moving metal surfaces which resists break down even under difficult conditions.

Castrol RX Diesel 15W-40 CI-4 Plus/E7
Castrol RX Diesel 15W-40 CI-4 Plus/E7 is a multi-purpose, heavy duty diesel engine oil. It is suitable for use in high speed 4-stroke diesel engines that use a broad range of fuel qualities. It is also compatible with diesel engines fitted with exhaust gas recirculation (EGR) systems.
Recommended by Castrol for use in all naturally aspirated and turbocharged diesel engines fitted in trucks, tractors, buses, LCV’s and off-highway equipment, agricultural and fixed plant machinery without DPF/DPD exhaust after-treatment devices.
Features and benefits
During its working life, your engine faces challenges from combustion by-products that can form deposits, and thicken the oil.
Castrol RX Diesel 15W-40 CI-4 Plus/E7 combats these issues in two ways:
- Contains cleaning agents which displace particles that may otherwise build up on your engine surfaces reducing deposits.
- Contains anti-oxidants which disrupt the chemical reactions that can lead to oil thickening.
- Castrol RX Diesel 15W-40 CI-4 Plus/E7 provides effective piston deposit control and maintains its viscosity to encourage long and healthy engine life.
