Advantages:
Castrol CRB Turbomax 10W-40 E4/E7 contains specially engineered DuraShieldTM Boosters that help fight the main causes of engine damage. In Industry testing, Castrol CRB Turbomax with DuraShield TM boosters delivers up to 40% better wear protection*.

CRB Turbomax with DuraShield TM boosters is proven in industry testing to provide protection to your engine in two ways:

1. 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 DuraShieldTM boosters helps to prevent the agglomeration of soot as well as protecting surfaces from wear. 
2. Secondly, CRB Turbomax with DuraShield TM boosters provides a protective layer on the moving metal surfaces which resists break down even under difficult conditions.
