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.
