VP GL-4 80w90 Gear Oil Hi-Perf 1 Qt

The VP GL-4 80w90 Gear Oil Hi-Perf 1 Qt from VP Racing is a conventional mineral-based gear lubricant engineered for demanding drivetrain and differential applications. This single-quart bottle delivers consistent protection in manual transmissions, differentials, and transfer cases where robust film strength and thermal stability are non-negotiable. VP Racing's formulation meets GL-4 performance standards, making it ideal for both street and high-stress environments where conventional gear oils are specified by manufacturers.

The 80W90 viscosity grade provides reliable shear stability across temperature ranges, ensuring proper film thickness during cold starts and sustained load-carrying capacity under heat and pressure. VP Racing's conventional formulation includes anti-wear and anti-oxidant additives that protect against gear scuffing, pitting, and sludge formation—critical factors in high-ratio gearboxes and heavy-load differentials. The 1-quart container is sized for top-ups, maintenance intervals, or complete fluid changes in compact or specialized drivetrain systems, with a net weight of 2.06 lbs per bottle.

This gear oil is suited for vintage vehicles, classic muscle cars, and modern manual transmission vehicles that call for GL-4 rated fluids. Users working on differentials, gearboxes, and transfer cases benefit from VP Racing's reputation for consistent performance in racing and street applications. Always verify your vehicle or equipment manufacturer's viscosity and performance specifications before application; the GL-4 rating confirms compatibility with most manual gearboxes and limited-slip differentials that do not require the extreme pressure additives of GL-5 formulations.
