Automotive Gear Oils are specially formulated to protect gear systems in cars, trucks, and commercial vehicles under high load and extreme temperature conditions. Designed with extreme pressure (EP) additives, they minimize wear, reduce friction, and ensure smooth gear shifting in manual transmissions, axles, and differentials.
Whether you're maintaining a light-duty passenger car or a heavy-duty truck fleet, our gear oils meet or exceed industry standards and provide dependable performance over extended drain intervals.
GL-5 75W90 Synthetic Heavy Duty Gear Oil
A fully synthetic, high-performance gear oil formulated for extreme pressure conditions. Offers excellent low-temperature fluidity for smooth cold starts and superior thermal stability for high-temperature protection. Ideal for modern vehicles operating across a wide range of temperatures and loads, including passenger cars, light trucks, and commercial fleets.
GL-5 80W90 Heavy Duty Gear Oil
A conventional mineral-based gear oil designed for general-purpose use in automotive gear systems. It provides solid protection against wear, rust, and oxidation. Suitable for manual transmissions, hypoid differentials, and rear axles in commercial vehicles and heavy-duty trucks.
GL-5 85W90 Heavy Duty Gear Oil
This grade offers a slightly higher viscosity than 80W90, providing increased film strength under high-load conditions. It ensures dependable gear protection in moderate to severe environments, making it a practical choice for vehicles operating under heavy loads and frequent stop-and-go driving.
GL-5 85W140 Heavy Duty Gear Oil
Engineered for extreme-duty applications, this gear oil is formulated to perform in high-load and high-temperature environments. It is commonly used in heavy trucks, off-highway equipment, and other demanding industrial and fleet applications where robust protection is essential.
GL-5 SAE 90 Heavy Duty Gear Oil
A monograde gear oil suited for stable, warm operating conditions. It provides strong protection for gear sets, particularly in older equipment or vehicles that require a consistent viscosity. Ideal for manual transmissions and differentials with moderate operating loads.
GL-5 SAE 140 Heavy Duty Gear Oil
A high-viscosity monograde oil designed for maximum gear protection in low-speed, high-load applications. Recommended for agricultural, construction, and off-road vehicles where gears are exposed to shock loading and extreme operating conditions.
