Zento Oil GearMax SAE 80W-90 is a premium-tier multipurpose gear lubricant specifically engineered for manual gearboxes, axles, and final drive units requiring extreme pressure (EP) protection. Manufactured in Malaysia using advanced USA Technology, this product meets the most stringent API GL5 standards to ensure maximum durability for gears and bearings under high-intensity operating conditions.
By combining highly refined base oils with a robust sulfur-phosphorus additive system, GearMax 80W-90 establishes an ultra-tough protective film, preventing metal-to-metal contact even under heavy-duty loads and shock-loading scenarios.
Key Performance Features
-
Superior Extreme Pressure (EP) Protection: Advanced additive technology prevents scuffing, pitting, and adhesive wear on gear teeth surfaces, ensuring longevity for high-torque components.
-
Thermal & Oxidation Stability: The formula resists oil thickening and sludge formation at high operating temperatures, maintaining consistent lubrication performance throughout the service interval.
-
Excellent Shear Stability: The SAE 80W-90 viscosity grade maintains a stable oil film thickness, protecting against oil thinning and ensuring reliable power transmission in all climates.
-
Corrosion & Foam Resistance: Formulated to protect copper-alloy bushings and steel components from rust and chemical corrosion, while anti-foam agents ensure continuous lubrication without air entrapment.
-
Reduced Mechanical Noise: High-quality friction modifiers help dampen vibrations, resulting in quieter gear operation and smoother shifting.
Recommended Applications
Zento Oil GearMax is the primary choice for vehicles and equipment requiring API GL5 standards:
-
Modern Heavy-Duty Transport: Manual transmissions, rear axles, and differential units of semi-trucks, buses, and delivery vans.
-
Passenger & Commercial Vehicles: SUVs, light trucks, and passenger cars requiring a robust 80W-90 viscosity profile for hypoid gear protection.
-
Construction & Agricultural Machinery: Final drives and gear reduction units in excavators, tractors, and harvesters operating in demanding environments.
-
Industrial Gear Systems: Enclosed gearboxes in industrial applications where an API GL5 high-pressure lubricant is specified.
