- Consider the Operating Conditions: Evaluate the vehicle’s operating conditions. Extreme temperatures, heavy loads, or off-road use can affect gear oil performance. Ensure the gear oil’s viscosity is suitable for the operating environment. In extremely hot conditions, a slightly higher viscosity oil might be beneficial, but always adhere to the manufacturer’s recommendations.
- Consult a Professional: If the problem persists or if you are unsure about any of the steps, consult a qualified mechanic. A professional can diagnose complex issues and provide the necessary repairs. A mechanic can also offer advice specific to your vehicle and its operating conditions.
