How often should the gear oil in a tricycle rear axle be changed?

[DiElliott]

It should be changed approximately every 20,000-30,000 km. Below is relevant information: Time: The interval may vary depending on the oil brand, but generally, it should be changed every 20,000-30,000 km. For new vehicles, the rear axle oil should be replaced during the 12,000 km maintenance, and then inspected every 24,000 km thereafter. If noticeable discoloration or thinning is observed, immediate replacement is necessary. Precautions: Different types of hypoid gear lubricants should not be mixed, as this may cause the lubricant to deteriorate and corrode the main and pinion gears. Avoid introducing moisture during storage and filling of gear oil to prevent decomposition and reduced lubrication effectiveness. When replacing deteriorated lubricant, ensure the main reducer is thoroughly cleaned to avoid contamination of the new oil.
