80w90 Gear Oil Case/12

The 80W90 Gear Oil Case/12 from Lucas Oil delivers professional-grade lubrication for heavy-duty manual transmissions, differentials, and transfer cases in trucks, SUVs, and off-road equipment. This case contains twelve 1-quart bottles of conventional gear oil formulated with limited-slip additives, making it ideal for fleet maintenance, workshop stock, or serious enthusiasts who demand reliable protection across demanding applications. Whether servicing light trucks or heavy equipment, this multi-unit case provides the volume and consistency needed for regular maintenance schedules.

The 80W90 viscosity grade offers excellent low-temperature flow while maintaining protective film strength under sustained high-load conditions typical of gear systems. Lucas Oil's limited-slip additive package reduces chatter and wear in differentials equipped with friction-enhancing clutches, preventing gear noise while safeguarding against metal-to-metal contact during acceleration and cornering. The conventional formulation resists thermal breakdown and oxidation, extending drain intervals and protecting critical gear teeth and bearing surfaces from premature wear. Each quart bottle is packaged for easy handling and precise measurement, with a total case weight of 25.45 lbs providing substantial inventory for commercial or personal use.

This case serves mechanics, fleet operators, and vehicle owners who require a trusted, cost-effective solution for multiple gearbox and differential applications. The 80W90 specification meets or exceeds API GL-5 performance standards, compatible with most manual transmissions and open differentials in domestic and import vehicles. Bulk purchasing through this twelve-bottle case reduces per-unit cost while ensuring consistent product quality across multiple service intervals. Store in a cool, dry environment away from moisture to maintain product integrity, and consult your vehicle's service manual to confirm viscosity requirements before use.
