Castrol Edge 5W-30 Synthetic Motor Oil, 5 Quarts

Castrol's most advanced engine oil is Castrol EDGE, a premium full synthetic designed for consumers demanding the best performance from their vehicles. Recommended by leading car manufacturers, Castrol EDGE is engineered with fluid titanium technology that physically alters the oil's behavior under pressure.

In today's engines, pressures have nearly doubled over the past three decades due to increased demands for performance and fuel efficiency. Greater pressure means more stress for the oil and potential for greater friction. As metal-to-metal contact increases, wear occurs and performance is reduced. Underneath the hood, pressures can reach 10 tons per square centimeter - equivalent to five cars resting on a high heel, relying solely on a micro-thin layer of oil for protection. A strong oil is therefore necessary to reduce friction and help increase horsepower and fuel economy.

Castrol's patented titanium technology provides documented performance in friction reduction, anti-wear, and deposit control protection, ensuring the strength and performance required to combat the elevated pressures in modern engines. Tested against industry standards, Castrol EDGE demonstrates superior capabilities:

• 3X stronger against viscosity breakdown than leading premium full synthetic and conventional oils (ASTM D6278 test, 5W-30 grade)
• 10X better high-temperature performance compared to API SP test limits (Sequence IIIH engine test)
• 6X better wear protection
• 1.4X better sludge protection versus API SP test limits (Sequence VH engine test)
• Meets ILSAC GF-6 requirements to prevent low-speed pre-ignition (LSPI) and timing chain wear

Engineered to excel under the extreme pressures of modern engines, Castrol EDGE's fluid titanium technology sets a new standard for engine oil performance and protection.
