GEAR OILS GL-4 EP 140

About GEAR OILS GL-4 EP 140

GEAR OIL GL-4 EP 140 is a premium quality extreme pressure (EP) gear lubricant specially formulated for heavy-duty automotive and industrial gear systems operating under high load and high temperature conditions. It is blended with high viscosity base oils and advanced EP additives to provide excellent protection against wear, rust, oxidation, and corrosion. This oil is designed to deliver reliable lubrication performance for manual transmissions, differentials, steering gears, and gearboxes requiring API GL-4 performance standards.

The SAE 140 viscosity grade ensures a thick lubricating film that protects gears and bearings during slow-speed, high-torque operations and in hot climatic conditions. GL-4 chemistry is particularly suitable for synchronized manual transmissions and gear systems containing yellow metal components such as brass or bronze synchros.

Applications

• Manual gearboxes and transmissions
• Differential and axle gear systems
• Steering gear assemblies
• Agricultural tractors and farm equipment
• Construction and mining machinery
• Commercial vehicles, trucks, and buses
• Industrial gear drives operating under moderate to heavy loads
• Hypoid and spiral bevel gears requiring API GL-4 oil
• Off-road vehicles and utility equipment

GEAR OIL GL-4 EP 140 is ideal for applications involving:

• High load carrying conditions
• Heavy shock loads
• High ambient temperatures
• Long operating hours
• Slow speed and high torque performance
