Richmond Gear Oil 80W90 GL-4 is a conventional hypoid gear oil engineered for manual transmission and differential applications where GL-4 performance is specified. This 1-quart bottle provides the viscosity and anti-wear protection required in light-duty to moderate-duty transfer cases, gearboxes, and limited-slip differentials commonly found in trucks, off-road vehicles, and recreational equipment.
The 80W90 viscosity grade indicates cold-flow characteristics (80W rating) that enable easier shifting and reduced drag in cold temperatures, paired with a baseline 90-weight film strength for boundary lubrication under load. GL-4 classification means this oil contains anti-wear additives and extreme-pressure (EP) agents suited for spiral-bevel gears and synchronizers, making it compatible with vehicles manufactured before the widespread adoption of GL-5 standards. The conventional (mineral) base delivers proven performance in older and classic drivetrains without the synthetic cost premium.
Technicians, fleet maintenance professionals, and vehicle owners maintaining manual-transmission trucks, Jeeps, and transfer cases turn to Richmond Gear Oil 80W90 GL-4 for routine drain-and-fill service and top-ups. The 1-quart container size fits typical single-quart topping needs or serves as a reserve for extended trips and field repairs. This product is verified by UPC and MPN identifiers for guaranteed authenticity and batch traceability.
