The core of car maintenance lies in regular upkeep and scientific operation, with a focus on key components such as engine oil, braking system, tyres, and filters. As the "blood" of the engine, mineral oil is recommended to be changed every 5,000 kilometres or 6 months, while fully synthetic oil can be extended to 10,000 kilometres or 12 months. The braking system is directly related to safety: brake pads need to be replaced immediately when their thickness is less than 3mm; the moisture content of brake fluid should be tested every 2 years or 40,000 kilometres (replacement is mandatory if it exceeds 3%); and any abnormal brake noise detected during daily use should prompt immediate inspection and repair. For tyre maintenance, check tyre pressure monthly (standard value: 2.2-2.5 Bar); replace tyres when tread depth falls below 1.6mm or bulges appear; and perform tyre rotation every 8,000 kilometres to ensure even wear. Replace the air filter every 10,000-20,000 kilometres (shorten the interval in sandy/dusty areas). The cabin air filter should be replaced every 6 months or 10,000 kilometres to maintain air quality. Other components requiring periodic maintenance include: spark plugs (nickel alloy: 20,000 km; iridium: 60,000 km), coolant (2-5 years depending on specification), and transmission fluid (automatic: 60,000 km). For new energy vehicles, pay special attention to the three-electric system (battery, motor, electronic control) and battery charge management (maintain 20%-80% capacity). Scientific maintenance practices significantly enhance driving safety and reduce long-term costs. Strictly follow the maintenance manual while adjusting schedules according to actual driving conditions.
