Xtreme Duty 85W-140 Gear Oil

Xtreme Duty™ 85W-140 Premium Performance Gear Oil is a high-performance, multi-grade lubricant formulated for drivetrain applications requiring heavier viscosity and dependable API GL-5 protection.

Quality base oils and a carefully selected extreme-pressure additive system provide excellent load-carrying capacity while protecting gears against scuffing and wear. Its heavier SAE 85W-140 viscosity helps maintain a durable lubricating film in heavily loaded components and applications operating at elevated temperatures.

Recommended for automotive axles, gear sets, conventional and limited-slip differentials, and conventional transmissions requiring API GL-5 performance.

Formulated for the Controlled Operating Environment™

The Controlled Operating Environment™ is The Hub Corporation’s system-level approach to preserving stable, protective conditions inside critical mechanical assemblies.

Xtreme Duty™ Gear Oil supports that environment by maintaining a durable lubricating film, controlling oxidation and deposit formation, protecting against rust and corrosion, and helping preserve seal integrity. The result is a cleaner, more stable lubrication environment designed to help drivetrain components perform reliably and reach their intended service life.

Key Features:

• High-viscosity protection: Provides dependable separation between loaded gear surfaces, particularly during high-load and high-temperature operation.
• Extreme pressure protection: Reduces the risk of scuffing, scoring, and premature gear damage in demanding drivetrain applications.
• Anti-wear protection: Preserves component condition, supports longer service life, and helps reduce avoidable drivetrain repairs.
• High-temperature film strength: Maintains dependable protection during sustained operation, heavy hauling, and other heat-generating service conditions.
• Rust and corrosion protection: Helps maintain component reliability during operation, storage, and equipment downtime.
