Heavy-Duty 680 Gear Oil for Industrial Gear Systems

Phillips 66® Extra Duty Gear Oil 680 delivers reliable protection for enclosed gear drives that handle the toughest loads. This ISO 680 gear oil is engineered for durability, performance, and cleanliness. It’s built to protect gears operating under high torque, high shock, and heavy continuous loads. Because of its advanced “Clean Gear” additive technology, it helps reduce sludge and deposits, keeping your gearbox clean and efficient.

This 680 gear oil works well in spur, bevel, helical, herringbone, and planetary gear systems. It’s also ideal for heavily loaded bearings in industrial and mining operations. Whether you’re running mills, crushers, or processing machinery, Phillips 66 Extra Duty Gear Oil 680 ensures consistent protection and smooth performance.

Strong Film Strength and Long-Term Stability

This high-viscosity ISO 680 gear oil forms a strong, durable film that resists wear, scuffing, and pitting. It protects metal surfaces under severe pressure and shock loading. Its excellent oxidation resistance and thermal stability help extend oil life while maintaining viscosity. That means fewer oil changes, less downtime, and better overall performance in demanding environments.

The oil also separates water quickly and resists foam formation. This keeps lubrication steady and prevents air pockets that can reduce gear efficiency.

Clean Operation and Rust Protection

With its “Clean Gear” additive package, Phillips 66 Extra Duty Gear Oil 680 keeps gearboxes free of harmful deposits. It prevents rust and corrosion, even in humid or contaminated environments. The result is cleaner operation, lower maintenance, and dependable long-term gear protection.
