Presidential 85W140 Gear Oil – Heavy-Duty GL-5 Gear Lubricant for Automotive and Industrial Equipment

Presidential 85W140 Gear Oil is a high-performance gear lubricant formulated to protect manual transmissions, differentials, gearboxes, and transfer cases in tough operating environments.

Designed for both industrial machinery and automotive use, this 85W140 gear oil delivers smooth operation and long-lasting component protection against wear, corrosion, and extreme pressure.

Engineered with high-quality base oils and advanced additive technology, this gear oil meets or exceeds industry standards. It also holds approvals from top manufacturers, including Mack GO-J, MAN 342 Type M1/M2, and SAE J2360. These certifications confirm its reliability in high-load, high-torque applications—particularly in commercial vehicles and off-road equipment with hypoid gears.

The robust formulation offers excellent thermal stability and oxidation resistance, helping to minimize sludge and varnish buildup.

As a result, gear life is extended, and overall performance is preserved. Additionally, its extreme pressure (EP) additives help protect gear surfaces from pitting, scoring, and scuffing under severe loads.

Unlike conventional lubricants, Presidential 85W-140 maintains its viscosity across a wide range of operating temperatures. This helps ensure consistent lubrication during cold starts and high-heat conditions. It also contains corrosion inhibitors to shield metal surfaces from rust. Meanwhile, its superior foam resistance promotes steady oil flow and efficient operation.

Because of these features, this gear oil helps reduce maintenance needs and extend service intervals. This leads to lower downtime and increased productivity.

Whether you’re running a fleet of trucks, maintaining agricultural equipment, or servicing heavy-duty industrial gearboxes, Presidential 85W-140 Gear Oil delivers the reliable protection you need. Proudly made in the USA, it reflects our commitment to quality, durability, and value.
