Differential oil Tornado TOR/17350, viscosity 50.000 cSt

Differential oil Tornado TOR/17350, viscosity 50.000 cSt is a heavy gear lubricant formulated for use in vehicle differentials and gearboxes that require a 50,000 cSt viscosity grade. The formulation delivers film strength and surface protection for hypoid and conventional gear sets, supports consistent lubrication under high loads, and helps manage operating temperatures and wear during normal driving and heavy-duty conditions.

Advantages

This differential oil provides a stable, high-viscosity lubricating film that reduces metal-to-metal contact and minimizes micro-pitting and wear on gear teeth. It helps preserve bearing surfaces and shaft seals through consistent shear stability and thermal resistance. The oil’s rheological properties contribute to quieter gear operation and reliable protection during prolonged high-load or low-speed, high-torque conditions.

Suitable for

• Automotive rear and front differentials requiring high-viscosity gear oil
• Manual and limited-slip differentials where a 50,000 cSt fluid is specified
• Heavy-load commercial vehicles and off-road equipment operating at low shaft speeds
• Maintenance and replacement during scheduled service intervals for vehicles with high-viscosity requirements

Key specifications

• Viscosity: 50,000 cSt (reported)
• Application: gear and differential lubrication
• Performance: formulated for high-load and low-speed, high-torque conditions
• Compatibility: intended for gearsets and bearings requiring a high-viscosity oil
• Physical form: viscous liquid designed for gear sump environments

How to use

Drain the old lubricant from the differential or gearbox according to the vehicle manufacturer’s service instructions. Clean the drain and fill ports and inspect seals, gaskets, and gear surfaces for wear or damage. Add the differential oil to the fill level specified by the vehicle maker, ensuring the unit is filled to the correct level while avoiding overfilling. After filling, operate the vehicle at low speed and check for leaks and normal gear engagement; recheck lubricant level when the unit has reached operating temperature if required by the service procedure.

Usage recommendations

Use this high-viscosity differential oil only where the vehicle or equipment manufacturer specifies a 50,000 cSt or equivalent viscosity grade, and follow all safety and disposal guidelines for used lubricants. For optimal performance, verify compatibility with seals and any limited-slip additives required by the differential design before use.
