At Topaz, we offer a complete range of manual and automatic transmission oils engineered to meet the performance demands of today’s drivetrains. Whether you’re operating a commercial fleet, industrial vehicle, or personal car, our gearbox oils and ATFs provide superior protection, smoother shifting, and extended transmission life.
Unlike engine oils, gearbox oils are designed to handle extreme pressures between gears, resist shear, and prevent wear under heavy torque loads. At Topaz, our GL-4 gear oils are blended from high-quality base oils and fortified with anti-wear, anti-corrosion, and friction-modifying additives to ensure optimum transmission performance.
Our GL-4 grade manual transmission oils are suitable for gearboxes and differentials where moderate EP (Extreme Pressure) protection is required without harming yellow metals such as brass or bronze.
A versatile gear oil offering balanced performance for most manual transmissions and final drives. Excellent thermal stability and wear resistance.
Ideal for vehicles operating under medium to heavy loads. Provides consistent viscosity and long-term gear protection.
Heavy-duty gear oil for extreme load and high-temperature conditions. Suitable for commercial trucks and off-road equipment.
Low-viscosity oil offering improved cold start performance and smooth gear shifting in colder climates.
Single-grade high-viscosity oil, excellent for high-load gearboxes and differentials where extreme pressure and thermal resistance are critical.
Topaz ATFs are engineered for smooth, consistent shifting, efficient power transfer, and maximum protection for automatic transmissions. Our fluids are suitable for a wide variety of automatic transmission systems.
Fully synthetic ATF meeting GM DEXRON-VI specification. Designed for modern transmissions with higher performance demands. Offers fuel savings, extended oil life, and excellent shift performance.
High-quality ATF suitable for a wide range of automatic transmissions. Provides smooth operation, oxidation resistance, and seal compatibility. Backward compatible with DEXRON II.
Formulated for older generation automatic transmissions. Ensures adequate lubrication, hydraulic performance, and protection in light-duty applications.
With over 17 years of experience in lubrication engineering, Topaz ensures that every drop of oil meets international standards and exceeds customer expectations. Our gearbox and transmission oils are trusted by fleet operators, mechanics, and industrial users across various sectors.
