Is Gear Oil the Same as Engine Oil?
1 Answers
Gear oil is not engine oil. It primarily refers to the lubricating oil used in transmissions and rear axles. The functions of gear oil include: 1. It is used in various gear transmission devices to prevent gear surface wear, scuffing, and sintering, thereby extending their service life and improving power transmission efficiency; 2. Gear oil should have excellent anti-wear and load-bearing properties, as well as appropriate viscosity; 3. It should possess good thermal oxidation stability, anti-foaming properties, water separation performance, and rust prevention. The hazards of not changing gear oil for a long time: 1. Gear oil working under high-speed and high-temperature conditions for extended periods can deteriorate and volatilize, exacerbating the wear of mechanical components and, in severe cases, damaging internal transmission parts; 2. If gear oil is not replaced for a long time, the vehicle may experience weak starts when cold.
