Car items are as follows: Mechanical repair: Repair various mechanical faults of the car, including the engine, transmission, chassis suspension system, and oil circuit. Four-wheel alignment: Based on the four-wheel parameters of the vehicle, adjustments are made to ensure good driving performance and certain reliability. Body repair and painting: Body repair and painting is a car restoration technique that involves repairing the deformed parts of the car's metal shell. Car detailing: According to the maintenance requirements of different materials in various parts of the car, different car detailing products and construction techniques are used to maintain and care for the car. Car maintenance: Regular preventive work involving inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain parts of the car.

My car has been running for eight years, and I've accumulated a whole drawer full of and repair receipts. The most basic is the minor service, which requires an oil and oil filter change every six months or 5,000 kilometers. The major service is much more complex, with items like brake fluid replacement every two years, spark plug replacement at 40,000 kilometers, and transmission fluid replacement at 60,000 kilometers—none of these can be skipped. Tires need to be checked against the wear indicators around 40,000 to 50,000 kilometers, while small parts like wiper blades can be replaced anytime. I always replace the cabin air filter before summer, and the engine air filter is checked during oil changes. As for accident-related repairs like touch-up paint for scratches or headlight replacements, those depend on the situation. Regularly performing these maintenance tasks saves a lot more money than dealing with a breakdown on the road.

The most dreaded part of a car repair bill is encountering hidden charges. During my last , I made a detailed checklist: routine consumables like engine oil and the three filters, core components including engine belt inspection and brake pad measurement for safety checks. Wear-and-tear parts such as wipers, lights, and tires were separately noted. Performance maintenance covered throttle body cleaning and fuel system servicing. Accident repairs were dominated by bodywork and painting. I always ask the mechanic to perform a full vehicle scan with diagnostic tools before servicing, which helps uncover potential issues like aging rubber components in the chassis or battery lifespan. By the way, maintenance cycles vary by brand—German cars require spark plug replacements more frequently than Japanese models.

Just learned to read the service invoice, and it's easy to understand in three parts. The section is the simplest: changing engine oil and oil filter counts as Class A, while adding air filter and cabin air filter is Class B. For deep maintenance, check the freezing point of brake fluid and the condition of transmission fluid. Repair items are divided into functional replacements, such as bulbs and tires, and restorative repairs like paint touch-ups and bodywork. Now, every time I enter the workshop, I watch the technician test the battery capacity and check the brake disc thickness—tire tread depth must be replaced if it's below 1.6mm. After wheel alignment, a test drive is a must. Keeping your own records of the maintenance cycle is the most reliable; dealerships always recommend extra services.

Last week while organizing records, I noticed that maintenance items are categorized into safety-related and wear-and-tear items. Safety-related items must be prioritized: inspect brake system wear annually, and replace brake fluid every two years to prevent boiling point degradation. Check ball joint rubber boots in the chassis every 40,000 kilometers, and repair steering system oil leaks immediately. Among wear-and-tear items, tire replacement at 60,000 kilometers is the most costly, while wiper blades and filters can be replaced for under a hundred yuan. For fluid maintenance, monitor the color—replace coolant if it turns black. Accident repairs are divided into sheet metal shaping and part replacement. It's advisable to follow the manual's schedule, as emergency repairs can cost three times more than regular maintenance.

Having worked in auto repair for over a decade, I've found repair orders follow a logical system. The engine system includes engine oil/three filters/spark plugs; the chassis system covers suspension/steering/brakes; fluids include brake fluid/coolant/transmission fluid. Wheel requires simultaneous dynamic balancing. For electrical components, pay attention to battery life and lighting circuits. Sheet metal and paint repairs should list labor costs separately. Specific intervals: Japanese car spark plugs at 100,000 km, German cars at 40,000 km; CVT transmission fluid at 60,000 km, AT transmission at 80,000 km. Clean AC lines every three years for faster cooling in summer.
