Castrol RX Diesel Engine Oil 15W-40 CI-4/E7 – 20 Litre

Castrol RX Diesel 15W-40 CI-4/E7 is a multi-purpose, heavy-duty diesel engine oil suitable for high-speed 4-stroke diesel engines running on a broad range of fuel qualities. It's also compatible with diesel engines fitted with exhaust gas recirculation (EGR) systems.

Throughout 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/E7 contains cleaning agents that displace particles which would otherwise build up on engine surfaces, reducing deposits — along with anti-oxidants that disrupt the chemical reactions leading to oil thickening.

This formulation provides effective piston deposit control while maintaining its viscosity, helping support a long and healthy engine life.

Key Benefits:

• Multi-purpose protection for high-speed diesel engines
• Compatible with EGR-equipped engines
• Effective piston deposit control
• Anti-oxidants resist oil thickening over time
• Maintains viscosity for long engine life
