Ruichang requires every 5,000 kilometers, and it is recommended to adhere to the schedule. Below is additional information: 1. Regular maintenance is crucial for vehicles, involving the replacement of wear-and-tear parts and fluids. Common wear-and-tear components include various filters, brake pads, brake discs, tires, spark plugs, wiper blades, and batteries. Vehicle fluids include engine oil, transmission fluid, coolant, brake fluid, and power steering fluid. 2. Some vehicles use an electric power steering system, which lacks hydraulic components and thus does not require power steering fluid. Only electro-hydraulic power steering systems and mechanical hydraulic power steering systems require power steering fluid. 3. During regular vehicle use, these fluids must be replaced periodically to maintain the car's condition and longevity. Engine oil is the most frequently changed fluid, often referred to as the engine's blood. In the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat.
