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 helps combat these issues in two ways:
1) It contains cleaning agents which help to displace particles that may otherwise build up on your engine surfaces reducing deposits.
2) It also contains anti-oxidants which help to disrupt the chemical reactions that can lead to oil thickening.
Castrol CRB Monograde 40 CF helps provide protection across multiple applications to encourage long and healthy engine life.
