75w85 Synthetic Gear Oil Case 12 x 1 Quart

The 75w85 Synthetic Gear Oil Case contains 12 quarts of premium DRIVEN Racing Oil formulated for serious automotive enthusiasts who demand superior differential and transmission protection. Whether you're running a modified street machine, a track-focused performance build, or a heavily modified truck, this synthetic blend is engineered to handle extreme pressure and temperature swings that conventional mineral oils simply cannot tolerate. The 75w85 weight classification makes this gear oil ideal for limited-slip and locking differentials, as well as manual transmissions that require robust film strength and anti-wear properties under aggressive driving conditions.

DRIVEN Racing Oil's synthetic formulation delivers exceptional thermal stability, meaning it resists breakdown under the sustained heat generated by high-horsepower applications and continuous hard driving. The 75w85 viscosity grade provides optimal film thickness at operating temperature while maintaining low-temperature pumpability, reducing startup wear on gears and bearings during cold cranking. This synthetic gear oil contains advanced anti-wear additives and extreme-pressure agents that protect ring and pinion gears, helical cuts, and bearing surfaces from scuffing and micropitting—critical for vehicles running boost, nitrous, or significant power modifications where gear loads exceed factory specifications.

Mechanics and tuners favor DRIVEN Racing Oil for differentials in rear-wheel-drive performance cars, muscle cars, and modified trucks where slip-percentage and torque bias demand premium lubrication. The 12-quart case provides sufficient volume for complete differential service, transmission refills, or multiple smaller jobs across a shop or fleet. This gear oil excels in applications ranging from street-strip cars to dedicated track machines, offering the chemical stability and anti-wear protection required by modern high-performance powerplants with upgraded internals or extreme duty cycles.
