How often should gear oil be changed in a sedan?
1 Answers
Sedans should have their gear oil changed every 2 years or 40,000 kilometers. The replacement steps are: 1. Remove the gear, drain the old gear oil completely, and tighten the drain plug; 2. Add new gear oil, ensuring the oil level does not exceed the f-line. The functions of gear oil include: 1. Lubricating the transmission system to reduce wear on gears and other moving parts, ensuring normal operation and extending service life; 2. Reducing friction and transmission losses in gear systems, improving mechanical efficiency; 3. Cooling transmission components; 4. Preventing corrosion and rust; 5. Reducing gear surface impact and transmission noise; 6. Gear oil has a cleaning effect, continuously washing away contaminants and solid particles accumulated on gear surfaces.
