Typical Properties

Property Typical Value Unit Notes
SAE Grade 85W-140 Multigrade oil designed for heavy-duty gear lubrication at various temperatures
Density @ 15°C ~0.890 – 0.900 g/cm³ Indicates oil mass per unit volume
Kinematic Viscosity @ 40°C 140 – 160 cSt Ensures proper lubrication flow at lower temperatures
Kinematic Viscosity @ 100°C 25 – 30 cSt Provides protection at high operating temperatures
Viscosity Index (VI) ≥95 High VI ensures stable viscosity across temperature changes
Pour Point ≤ –18 °C Ensures fluidity in cold conditions
Flash Point (COC) ≥200 °C High flash point ensures safety at high operating temperatures
Timken OK Load ≥60 lb Load-carrying capacity indicating resistance to wear
Sulfated Ash ≤1.0 % wt Relates to the ash produced by the oil’s additives, important for emissions
Copper Corrosion 1a – 1b Ensures protection against corrosion in metal components
Foaming Characteristics Pass (Seq I–III) Prevents foam formation in the system, ensuring smooth performance
Extreme Pressure (EP) Properties Excellent Provides superior protection under high-load and high-pressure conditions

A heavy-duty, multigrade hypoid gear lubricant formulated with premium mineral base oils and advanced extreme-pressure (EP) additives. Designed to protect high-load gear sets and differentials across a broad temperature range.


Applications

  • Automotive Differentials & Transfer Cases: Ideal for heavy-duty trucks, buses, and SUVs requiring robust hypoid gear protection.

  • Industrial Gearboxes: Suited for enclosed gear drives in crushers, conveyors, and presses under severe load.

  • Off-Highway Equipment: Optimized for construction, mining, and agricultural machinery operating under high stress and temperature.


Key Benefits

  1. Superior Extreme-Pressure Protection
    EP additives create a resilient film on gear teeth, preventing metal-to-metal contact and reducing wear under heavy loads.

  2. Thermal and Oxidation Stability
    Resists oil breakdown and deposit formation at elevated temperatures, extending oil and equipment life.

  3. Wide Temperature Performance
    The 85W-140 grade ensures easy flow at moderate cold starts (85W) and maintains a thick lubricating film at high operating temperatures (140).

  4. Corrosion and Rust Inhibition
    Specialized inhibitors protect gear housings and shafts from moisture and corrosive elements, crucial for off-road and marine applications.

  5. Foam Control and Air Release
    Anti-foam agents ensure rapid air separation, preventing cavitation and ensuring consistent lubrication.


Formulation

  • Base Oils: High-viscosity paraffinic mineral oils for enhanced film strength.

  • Additives: EP compounds (sulfur/phosphorus), antioxidants, corrosion inhibitors, foam suppressants, and pour-point depressants.


Performance Standards

  • API GL-5 (hypoid gear service)

  • MIL-PRF-2105E (U.S. military spec for severe-service gear oils)

  • OEM approvals from major differential and axle manufacturers


Packaging

Available in 1 L, 4 L, 20 L, and 200 L containers to suit individual service bays up to large fleet maintenance.
