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.

Castrol RX Super 15W-40 CJ-4/E9 with DuraShield 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 DuraShield boosters provides a protective layer on the moving metal surfaces which resists break down even under difficult conditions
