Castrol CRB Monograde 40 CF/CF-2 is a diesel engine oil designed for use in heavy duty diesel engines, hydraulic systems and transmissions that specify the use of monograde diesel engine oil.
Advantages:
During its working life, your engine faces challenges from combustion by-products that can form deposits, and thicken the oil. Castrol CRB Monograde 40 CF/CF-2 combats these issues in two ways:
-
It contains cleaning agents which displace particles that may otherwise build up on your engine surfaces reducing deposits.
- It also contains anti-oxidants which disrupt the chemical reactions that can lead to oil thickening.
Castrol CRB Monograde 40 CF/CF-2 provides protection across multiple applications to encourage long and healthy engine life
