Automotive maintenance management must follow the principles of systematic periodicity and dynamic adjustment, with the core being regular maintenance of key components and adaptation to local climate and road conditions. In basic maintenance, oil and oil filter replacement is a top priority: fully synthetic oil is recommended to be changed every 10,000 kilometres or 12 months, semi-synthetic oil every 7,500 kilometres or 9 months, and mineral oil every 5,000 kilometres or 6 months. If the vehicle is often driven for short distances or in traffic jams, the interval should be shortened by 20%. The three filters (oil filter, air filter, and cabin air filter) need to be maintained simultaneously: the air filter should be replaced every 10,000 kilometres, the cabin air filter is recommended to be replaced every 6 months or 10,000 kilometres, and the frequency should be doubled in dusty areas. Tyres must be replaced if the tread depth is less than 1.6mm or bulges appear, and tyre rotation should be performed every 8,000 to 10,000 kilometres to extend their service life. The brake system requires regular inspection: brake pads should be replaced when their thickness is less than 3mm, brake fluid should be replaced every 2 years or 40,000 kilometres, and a water content exceeding 3% will endanger braking safety. For long-term maintenance, attention should be paid to transmission fluid (every 60,000 kilometres for automatic transmissions), timing belt (inspected every 80,000 to 100,000 kilometres), and coolant (every 2 years or 40,000 kilometres); deteriorated coolant may cause engine corrosion. Car owners can independently replace wiper blades, top up windshield washer fluid, and perform simple filter maintenance, but it is recommended that vehicles under warranty be maintained at authorised service centers to avoid disputes. Through regular inspections and on-demand maintenance, the risk of breakdowns can be significantly reduced, the service life of the vehicle can be extended to more than 10 years, and long-term maintenance costs can be saved by approximately 30%.
