Is this product for you?
New and advanced Castrol RX Super 15W-40 CJ-4/E9 with specially engineered DuraShield Boosters delivers 40% better wear protection vs. industry standard limits. 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:

Castrol RX Super 15W-40 CJ-4/E9 with DuraShieldTM boosters helps to prevent the agglomeration of soot as well as protecting surfaces from wear.
2. Castrol RX Super 15W-40 CJ-4/E9 with DuraShieldTM boosters provides a protective layer on the moving metal surfaces which resists break down even under difficult conditions
