Advantages:

During its working life, your engine faces challenges from combustion by-products that can form deposits, and thicken the oil. Castrol CRB Multi 15W-40 CH-4 combat 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 Multi 15W-40 CH-4 helps provide protection across multiple applications to encourage long and healthy engine life.
