Key Benefits

Why Choose DELUXE SAE 85W140 GL-5

Heavy-duty gear oil engineered for manual transmissions, differentials, and final drives to deliver strong film strength, smooth operation, and dependable anti-wear protection.

Extreme-Pressure Load Protection

API GL-5 additive chemistry helps protect heavily loaded gear teeth from scuffing and scoring under severe torque.

Smooth Shift Performance

Helps maintain consistent lubrication across temperature changes for smooth engagement and reduced drivetrain noise.

Thermal & Oxidation Stability

Resists oxidation and viscosity loss at high operating temperatures to support long component life.

Reliable Anti-Wear Protection

Helps protect gears and bearings against micro-pitting and wear during continuous high-load operation.

Corrosion & Rust Control

Inhibitors help protect steel and yellow-metal components from corrosion in humid and variable environments.

Seal-Friendly Formulation

Balanced additive system supports seal compatibility and helps reduce leakage risk in demanding drivetrain service.
