The GP-1 85W140 Gear Oil Case from DRIVEN RACING OIL is a professional-grade synthetic lubricant engineered for high-performance differentials, transfer cases, and heavy-duty manual transmissions in both street and track applications. This 12-quart case format is ideal for enthusiasts and mechanics who service multiple vehicles or maintain fleet equipment requiring consistent, extreme-pressure gear protection. Whether you're rebuilding a performance differential or maintaining a modified truck's drivetrain, this gear oil delivers the viscosity stability and anti-wear additives that serious automotive work demands.
The 85W140 viscosity rating provides robust film strength across a wide temperature range—85W winter rating ensures pumpability in cold starts, while the 140 summer rating maintains shear stability under sustained high-load conditions typical of limited-slip differentials, track driving, and heavy towing. DRIVEN RACING OIL formulations incorporate advanced anti-scuff and anti-wear chemistry specifically designed to protect hypoid gears and synchronizers from the extreme pressures generated during acceleration, cornering, and load transfer. This synthetic construction resists viscosity breakdown better than conventional mineral oils, extending drain intervals and protecting precision gear teeth from micro-welding and surface distress.
Mechanics and performance builders choose this gear oil for differentials equipped with aggressive gear ratios, limited-slip clutches, and locking mechanisms where conventional fluids fall short. The 12-quart case provides enough volume for a complete differential service plus reserve for top-offs, making it practical for shops and dedicated enthusiasts managing multiple drivetrain systems. Confirm your vehicle's differential capacity and gear type before installation—some modern vehicles and limited-slip units have specific fluid requirements, though most manual gearboxes and traditional open differentials thrive on this DRIVEN RACING OIL specification.
