SAIC Volkswagen vehicles generally have a maintenance interval of every 7,500 kilometers as specified by the manufacturer. This interval is determined based on various factors such as road conditions, air quality, fuel quality, and more. SAIC Volkswagen vehicle maintenance items include: Engine oil, oil filter, fuel filter, air filter, and cabin air filter. For vehicles that have traveled 60,000 kilometers, the transmission fluid typically only needs to be replaced every 100,000 kilometers, and some owners may even have transmission fluid that is maintenance-free for the lifetime of the vehicle. Engine spark plugs and timing belts can also last for over 80,000 kilometers. If spark plugs require maintenance, some engine cylinders may not fire properly, leading to symptoms such as engine shaking. The timing belt is a crucial component of the engine's valve train system, connected to the crankshaft to ensure proper engine intake and exhaust timing. After prolonged use, timing belts may break, and once damaged, they cannot be replaced by the owner. It is recommended to replace them approximately every 80,000 kilometers. Key points to note for vehicle maintenance: Regular tire pressure checks and adjustments are among the most important aspects of vehicle safety inspections. Insufficient tire pressure can lead to abnormal wear or internal tire damage, while excessive tire pressure makes the tires and rims more susceptible to deformation from impacts with uneven road surfaces and may even cause blowouts. Do not blindly pursue higher-octane gasoline. The octane rating is merely a parameter that indicates a gasoline's resistance to knocking and has no direct correlation with the cleanliness or fuel efficiency of the gasoline. Higher octane ratings do not necessarily mean better performance, and even high-end vehicles do not always require high-octane gasoline.
