75w90 Gear Lube 1 Qt

MOBIL 1 75W90 Gear Lube is a premium synthetic gear oil formulated to deliver superior protection and performance in limited-slip differentials and manual transmissions. This 1-quart bottle contains the exact viscosity and additive package required for optimal operation in vehicles with limited-slip differentials, where conventional gear oils may cause chatter or slip.

The 75W90 viscosity grade ensures reliable film strength across a wide temperature range—the 75W rating provides cold-start flow in winter conditions, while the 90 rating maintains protective viscosity at operating temperatures. The limited-slip additive package is engineered to reduce noise and wear in differentials equipped with friction clutches or cone-type limited-slip units. MOBIL 1's synthetic base stock resists oxidation and thermal breakdown better than conventional mineral oils, extending service life and protecting against rust and corrosion in varied driving environments.

This product is designed for serious drivers who depend on proper differential lubrication—whether maintaining off-road vehicles, performance cars, trucks used for towing, or machinery with similar drivetrain requirements. The 1-quart size allows for top-ups between full drain intervals or serves as a convenient backup supply for those who perform their own maintenance. Verify your vehicle's service manual to confirm 75W90 compatibility before use.

Synthetic gear oils like this 75W90 formulation have become the standard in modern automotive and equipment applications where extended drain intervals and maximum protection are priorities. The limited-slip additive ensures this oil meets the specific demands of differentials that require smooth, predictable clutch engagement.
