How often should the rear axle oil of Wuling Hongguang S be changed?
2 Answers
The replacement interval for the rear axle oil of Wuling Hongguang S is 2 to 3 years or 40,000 kilometers, whichever comes first. The rear axle oil used in vehicles is a specialized gear oil. Since the gears in the rear axle are helical, hypoid gear oil is generally used. Front-wheel-drive vehicles have specialized transmission oil, while mid-to-high-end vehicles now use specialized differential oil. The Wuling Hongguang S is a model launched by SAIC-GM-Wuling based on the Wuling Hongguang series, positioned between commercial vehicles and passenger cars. With its sleek exterior design, versatile and practical spacious interior, perfect balance of power and fuel efficiency, as well as strong performance in handling and safety, it has revolutionized the traditional perception of commercial vehicles.
As a long-time owner of the Wuling Hongguang S, having driven it for several years, the replacement interval for the rear axle oil should be based on actual conditions. Generally, manufacturers recommend changing it every 40,000 kilometers or every two years. However, if you frequently carry heavy loads or drive on mountainous roads, the oil may degrade faster, possibly requiring replacement at 30,000 kilometers or even sooner. An oil change isn’t expensive—just around a hundred yuan. Neglecting it can lead to oil deterioration and severe wear on the rear axle gears, making repairs costly and labor-intensive. I recall the manual clearly stating that regular oil changes extend the vehicle’s lifespan. Don’t skip it—just visit a reputable service center to get it done.
