Premium Mineral 85W-140 Gearbox & Differential Oil (LSD85W140) - LSD85W140-1E

Premium Mineral 85W-140 Gearbox & Differential Oil (LSD85W140)

Nulon Premium Mineral 85W-140 Limited Slip Differential Oil (LSD85W140) is developed for limited slip differential applications to withstand high loads and repeated shock-load conditions. Also ideal for conventional differentials and vehicles that operate under heavy duty conditions such as 4x4, towing, or carrying heavy loads. Nulon LSD85W140 is suitable for use where API GL-5 or GL-6 (obsolete) is recommended.

LSD85W140 is formulated using the synergy of high viscosity base fluids with an extreme pressure additive system, corrosion inhibitor and friction modifier technology. This enhances wear protection and corrosion resistance and provides smoother operation in limited slip differentials. LSD85W140 is engineered using high shear stable material to withstand extreme load and maintain viscosity.

LSD85W140 meets the severe requirements of API MT-1 suitable for use in non-synchronized manual transmissions and final drive axles in buses and heavy-duty trucks. LSD85W140 provides superior protection against thermal degradation during high operating temperature, oil seal deterioration, and component wear.
LSD85W140 is modified with anti-friction additive to reduce and even eliminate clutch chatter in vehicles fitted with limited slip differential. It elevates smooth operation for either limited slip or conventional hypoid differentials.

For enhanced anti-wear performance use Nulon Smooth Shift Manual Gearbox & Diff Treatment. Part No: G70
