Features:

New and advanced Castrol RX Super 15W-40 CJ-4/E9 with specially engineered DuraShield™ Technology delivers *40% better wear protection.

One of the major causes of engine damage is abrasive wear. Castrol RX Super 15W-40 CJ-4/E9 with DuraShield™ Technology protects your engine in two key ways:

• Soot Management: Under severe conditions, soot can form large particles that displace oil and cause metal-to-metal contact. DuraShield™ Technology helps prevent soot agglomeration and protects metal surfaces from wear.
• Protective Layer: Forms a durable protective film on moving metal surfaces that resists breakdown even under tough conditions.

Based on industry standard testing.
