Castrol CRB Turbomax contains specially engineered DuraShield Boosters that help fight the main causes of engine damage. In Industry testing, Castrol CRB Turbomax with DuraShield boosters delivers up to 40% better wear protection*. CRB Turbomax with DuraShield boosters is proven in industry testing to protect your engine in two
ways:

• Firstly, under severe engine operating conditions, soot can agglomerate to form large particles which displace oil on moving metal surfaces. This results in metal-to-metal contact. CRB Turbomax with DuraShield boosters helps to prevent the agglomeration of soot as well as protect surfaces from wear.
• Secondly, CRB Turbomax with DuraShield boosters provides a protective layer on the moving metal surfaces which resists breaking down even under difficult conditions
