primarily involves servicing the engine system, transmission system, air conditioning system, etc., with the aim of keeping the vehicle clean, maintaining normal technical conditions, eliminating potential hazards, preventing faults, and extending the service life. Also known as vehicle upkeep, car maintenance refers to the periodic preventive work of inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts related to the vehicle. Maintenance is divided into minor and major services. Minor maintenance generally refers to the routine maintenance tasks performed at the manufacturer-specified time or mileage to ensure vehicle performance, mainly including oil and oil filter replacement. Major maintenance refers to the regular service performed at the manufacturer-specified time or mileage, which includes replacing the oil, oil filter, air filter, and fuel filter.

For my regular car , I usually need to change the engine oil and oil filter every 5,000 kilometers; otherwise, the engine gets noisy and consumes more fuel. Checking tire pressure is crucial—it might be too low in cold weather and can expand in summer, so I keep a tire pressure gauge handy for regular checks. The air filter also needs frequent cleaning, as too much dust affects air intake efficiency. I prefer replacing it myself—it's simple and hassle-free. Brake fluid and coolant should be replaced every two years to prevent accidents, and always check if the lights are functioning properly. Regular minor maintenance at a reliable shop doesn’t cost much but saves a lot of trouble—don’t wait until a major repair is needed to regret it. Remember the maintenance schedule in the manual, as it varies by car; for example, SUVs might be more durable. In short, a mix of DIY and professional care keeps your car running smoothly and extends its lifespan.

DIY car can be quite fun. Start with replacing the air filter – just buy the right model online, and with basic tools like a screwdriver and wrench, it takes about ten minutes. Check tire pressure monthly, keeping it between 230-250 kPa, and rotate the tires for even wear. Use sandpaper to clean rust off battery terminals for quick starts. For tasks beyond your skills, like changing transmission fluid or inspecting the brake system, visit a quick-service shop to avoid mishaps. Always wear gloves for safety. Saving on small expenses means more to spend on things you love. Car maintenance is like health care – attention to detail ensures longevity, so don’t slack off.

The core of is to ensure the normal operation of various vehicle systems. Change the engine oil regularly to lubricate the engine, and replace the oil filter at the same time. Pay attention to tire wear and balance to prevent slipping. Replace brake pads if the thickness is insufficient. Clean the cooling system to remove scale and ensure heat dissipation. Test the brightness and response of lights. Clean the battery electrodes. Handle simple tasks yourself, but for complex tasks like ABS calibration, consult a technician. In short, perform phased maintenance based on mileage to maintain efficient operation and avoid unexpected failures.

is crucial for safe driving and should never be neglected. Expired engine oil can damage the engine, and worn-out tires are prone to dangerous blowouts. I insist on a comprehensive inspection every quarter: replacing the three filters, testing brake fluid concentration, and adjusting headlight angles. Problems on the highway can be terrifying—spending a little on prevention is far more cost-effective than major repairs. Make it a habit to check tire conditions after parking and test lights and signals before driving. Safety is no trivial matter; proper maintenance is about loving your car and your life.

is a long-term investment that saves money. Changing oil and filters costs a few hundred, but extends engine life, saving thousands in repairs. Regular tire rotation and alignment prolongs tire life, avoiding premature replacement costs. Proper battery maintenance reduces the risk of roadside breakdowns. I set calendar reminders for minor maintenance every 5,000 km and major inspections every two years, including coolant and brake fluid changes. Well-maintained cars also command higher resale values, minimizing overall ownership costs. From an economic perspective, regular maintenance is a smart choice.
