Strong Wear Protection and Long Oil Life

Phillips 66 Extra Duty Gear Oil 320 handles extreme pressure with ease. Its EP additives create a strong oil film that resists wear, scuffing, and pitting. The oil’s thermal stability keeps it performing under high heat. Because it resists oxidation, it lasts longer and reduces maintenance downtime.

This 320 gear oil also separates water quickly and prevents foam buildup. You get smoother gear operation, less friction, and consistent performance shift after shift.

Cleaner, Longer-Lasting Gearbox Protection

Thanks to its “Clean Gear” additive system, Phillips 66 Extra Duty Gear Oil 320 keeps internal surfaces spotless. It protects against rust and corrosion while maintaining film strength even under shock loads. The result is cleaner gearboxes, quieter operation, and dependable uptime.
