Motul Gear Competition 75w-140 is engineered to excel in scenarios where standard gear oils fall short. Its fully synthetic nature means it resists thermal breakdown and maintains its lubricating properties even when components are subjected to immense heat and friction.
For competition vehicles, this oil provides the necessary film strength to protect highly stressed gear sets in sequential gearboxes and hypoid differentials. Drivers can expect reduced wear and smooth operation during aggressive shifts and continuous high-load situations, such as circuit racing, drag racing, or off-road endurance events.
In demanding applications where heavy loads and high temperatures are common, like towing heavy trailers with performance vehicles or off-roading, this lubricant ensures that transmissions and limited slip differentials remain protected. The 75w-140 viscosity rating ensures effective lubrication from cold startup to peak operating temperatures, preventing metal-to-metal contact and prolonging component life.
The limited slip differential compatibility is a key benefit, preventing the "chatter" often associated with LSDs and ensuring consistent torque transfer, which is crucial for traction and control in high-performance driving.
Setup:
Consult your vehicle's service manual: Always refer to the manufacturer's specifications for the correct gear oil type, viscosity, and fill volume for your transmission and differential.
Drain old fluid: Ensure the vehicle is safely raised and the old gear oil is completely drained from the transmission and/or differential.
Refill: Using a suitable pump or funnel, slowly refill the component with Motul Gear Competition 75w-140 until it reaches the specified level. Avoid overfilling.
Check for leaks: After refilling, inspect drain and fill plugs for any leaks.
Compatibility:
Transmissions: Suitable for gearboxes requiring a 75w-140 viscosity. Always confirm your transmission type and specifications.
Differentials: Specifically designed for limited slip differentials and can also be used in conventional differentials requiring 75w-140.
Not for Engines: This is a gear oil, not engine oil. Do not use in internal combustion engines.
Care & Storage:
Storage: Store the bottle in a cool, dry place away from direct sunlight and extreme temperatures. Keep the cap tightly sealed to prevent contamination.
Disposal: Dispose of used gear oil responsibly according to local environmental regulations. Never pour used oil down drains or onto the ground.
Handling: Avoid prolonged skin contact. Wear gloves and eye protection during handling.
