Description

Solar Manual Gear Oil SAE 80W-140 GL-5 is a high-performance, multi-grade gear lubricant formulated with premium quality base stocks and advanced extreme pressure (EP) additive chemistry. It is engineered to meet the demanding requirements of API GL-5 specifications for hypoid and spiral bevel gears operating under severe service conditions. This gear oil ensures superior protection against wear, oxidation, and thermal degradation, delivering long-lasting performance in high-torque and high-load gear systems.

Available API

80W140

Applications

Hypoid and spiral bevel gear differentials and axles in commercial fleets, 4WD vehicles, and industrial equipment.
Gear systems subjected to high torque, shock loads, and extreme pressure conditions.
Applications where API GL-5 and SAE 80W-140 multi-grade performance is specified.

Features & Benefits

Superior Extreme Pressure Protection: Excellent load-carrying capacity to protect gears and bearings from scuffing, pitting, and wear.
Wide Temperature Range Performance: Maintains viscosity and film strength across a broad range of temperatures for year-round protection.
Excellent Oxidation & Thermal Stability: Minimizes sludge and varnish formation, enabling extended drain intervals.
Outstanding Rust & Corrosion Protection: Guards metal surfaces against rust, corrosion, and moisture contamination.
Shear Stability: Maintains viscosity grade under severe mechanical stress for consistent performance.
Seal Compatibility: Compatible with commonly used elastomers, reducing the risk of leaks and seal degradation.

Performance Standards

Recommended for use in hypoid gear sets, axles, differentials, and final drives requiring API GL-5 level protection.
Suitable for commercial trucks, buses, heavy-duty off-road equipment, agricultural and construction machinery.
Ideal for severe service applications involving high loads, high speeds, and elevated operating temperatures.
