trucks, tractors, buses, LCV’s and off-highway equipment, agricultural and fixed plant machinery without DPF/DPD exhaust after-treatment devices.

FEATURES & 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.
