FEATURES & BENEFITS
New and advanced Castrol RX Super 15W-40 CJ-4/E9 with specially engineered DuraShield Boosters delivers 40% better wear protection*.
One of the main causes of damage in modern engines is abrasive wear. Castrol RX Super 15W-40 CJ-4/E9 with DuraShield Boosters is proven in industry testing to provide protection to your engine in two ways:
- Under severe engine operating conditions soot can agglomerate to form large particles which displace oil on moving metal surfaces and results in metal to metal contact. DuraShieldTM Boosters helps to prevent the agglomeration of soot as well as protecting surfaces from wear.
- Provides a protective layer on the moving metal surfaces which resists break down even under difficult conditions.
