Hypoid Gear Oil MP GL-5 85w140 Case 12x1Qt

AMALIE Hypoid Gear Oil MP GL-5 85W140 is a high-performance, conventional hypoid gear lubricant formulated for multi-purpose drivetrain protection. This case of twelve 1-quart bottles delivers the extreme pressure additives and limited-slip clutch compatibility required in heavy-duty differentials, transfer cases, and manual transmissions operating under severe conditions.

The 85W140 viscosity grade provides robust film strength across temperature extremes, critical for hypoid gear sets where tooth contact pressures exceed 200,000 PSI. The GL-5 specification incorporates anti-scuff additives that prevent micro-welding between gear teeth during shock loading—common in off-road, towing, and military vehicle operations. Limited-slip additive chemistry ensures smooth, predictable clutch pack engagement without chatter or noise, maintaining differential lock behavior across brake-to-accelerator transitions.

This product is engineered for fleet maintenance, off-road recovery equipment, agricultural machinery, and any drivetrain application where conventional (non-synthetic) hypoid protection is specified. The case quantity makes it practical for service intervals across multiple vehicles or for shops maintaining inventory of critical drivetrain fluids. AMALIE's heritage in industrial lubrication translates to formulations tested under real-world shock loads and extended drain intervals.

GL-5 oils remain the industry standard for modern hypoid differentials and are backward-compatible with older GL-4 equipment. Always verify your vehicle's service manual for viscosity and additive requirements before substitution, as some limited-slip systems specify GL-4 exclusively to avoid clutch lock-up.
