How often should the gear oil be changed in a Volkswagen Santana?
1 Answers
Gear oil does not need to be changed during the break-in period. Generally speaking, gear oil should be replaced every 60,000 kilometers. Different types of transmissions and drive axles use different viscosity grades. Small passenger vehicles require a viscosity grade of 75w--90, while large trucks and drive axles require a viscosity grade of 80w--90. Composition of gear oil: Gear oil is primarily composed of petroleum-based lubricating base oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an important type of lubricating oil. Function of gear oil: It is used in various gear transmission devices to prevent tooth surface wear, scuffing, sintering, etc., thereby extending their service life and improving power transmission efficiency. Characteristics of gear oil: Gear oil should have excellent anti-wear and load-bearing properties, as well as suitable viscosity. Additionally, it should possess good thermal oxidation stability, anti-foaming properties, water separation performance, and rust prevention capabilities.
