This Motul Gearbox 80w-90 EP oil delivers reliable performance in crucial drivetrain components. In manual transmissions, it facilitates smooth gear engagement by reducing friction and wear on syncros and gear teeth, preventing grinding and extending the life of the gearbox. For transfer cases, which distribute power between axles, the oil's thermal stability helps manage heat generated during operation, especially under varying loads or off-road conditions. Most importantly, for hypoid differentials (specifically those without limited slip features), the extreme pressure (EP) additives are vital. These additives form a protective layer on gear surfaces, preventing metal-to-metal contact even under the immense pressure and sliding action characteristic of hypoid gears. This safeguards components from scoring and pitting, critical for the differential's longevity and quiet operation. The 1-liter size is convenient for typical fluid changes.
Preparation: Ensure the vehicle is on a level surface and safely supported if lifting is required. Allow the transmission or differential to cool slightly if it's been recently run.
Locate Fill/Drain Plugs: Identify the drain plug (usually at the lowest point) and the fill plug on the component (transmission, transfer case, or differential).
Drain Old Fluid: Place a suitable drain pan beneath the drain plug. Carefully remove the drain plug and allow all old fluid to empty. Replace the drain plug, ensuring it's tightened to the manufacturer's specified torque.
Fill New Fluid: Remove the fill plug. Using a fluid pump or syringe, slowly add Motul Gearbox 80w-90 EP oil until the fluid just begins to seep out of the fill hole. This indicates the correct level.
Secure: Replace and tighten the fill plug to the manufacturer's specified torque. Clean any spilled oil.
This oil is specifically designed for manual transmissions, transfer cases, and hypoid differentials without limited slip systems. Always refer to your vehicle manufacturer's service manual or owner's handbook for the precise gear oil viscosity and specification (e.g., GL-4, GL-5) required for your specific make and model. Using the incorrect oil can lead to premature wear or component failure.
Gear oil is a long-life fluid, but it does degrade over time and mileage.
Follow Manufacturer's Schedule: Adhere strictly to your vehicle manufacturer's recommended service intervals for gear oil changes. These can vary significantly based on vehicle type and usage (e.g., standard driving vs. heavy towing).
Inspect Regularly: Periodically check for leaks around the transmission or differential seals.
Check Fluid Level: If accessible, check fluid levels during routine maintenance to ensure proper lubrication.
Disposal: Dispose of used gear oil responsibly at an authorized recycling center.
