The core items of basic car maintenance include oil and filter replacement, air and air-conditioning filter maintenance, key fluid inspection, and tyre care. Engine oil needs to be replaced regularly according to its type: mineral oil is recommended to be replaced every 5,000 kilometres or 6 months, semi-synthetic oil every 7,500 kilometres, and fully synthetic oil can last up to 10,000 kilometres. The air filter should be replaced every 10,000 to 20,000 kilometres to ensure clean engine air intake, while the cabin air filter is recommended to be replaced annually or every 10,000 kilometres to maintain interior air quality. For the braking system, brake fluid should be replaced every 2 years or 40,000 kilometres, and brake pads must be replaced immediately when worn to the limit. Tyres require regular pressure checks, wear inspection, and balancing, with replacement recommended every 5 years or 60,000 to 80,000 kilometres. Manual transmission fluid should be changed every 60,000 kilometres, whereas automatic transmission fluid replacement intervals should follow the vehicle manual. Spark plug replacement intervals range from 20,000 to 100,000 kilometres depending on material type. Battery voltage should be tested after two years of use. Actual maintenance schedules may vary based on driving habits, environmental conditions, and vehicle specifications, so always consult the owner's manual or professional technicians for guidance.
