What are the precautions and common knowledge for car maintenance?

Here are the precautions for car maintenance: 1. Verify vehicle information: Check relevant details such as license plate number, chassis number, and in/out time to prevent billing errors. 2. Reclaim spare parts: If there are damaged parts, try to reclaim them to prevent unscrupulous businesses from substituting inferior products, which could pose risks to the car owner. 3. Labor hours: During repairs, labor costs are usually included. If billed separately, it may result in duplicate charges. For example, when replacing brake calipers, the brake pads must be removed, and the labor cost should be included in the repair fee. If the bill lists additional labor fees for caliper repair, you can question it. 4. Mileage: For serious car issues, the vehicle might need to stay at the repair shop for a while. Note the mileage to prevent dishonest mechanics from taking the car out for joyrides. Generally, test drives should not exceed 20 km. 5. Avoid unnecessary major repairs: Some shops may exaggerate minor issues or suggest unnecessary repairs to inflate costs. If unsure, ask for proof. 6. Check repair items: Understand the maintenance operations being performed. If they exceed the agreed service scope, consult the service advisor or mechanic. 7. Take excess oil: It's hard to buy the exact amount of oil needed. For example, if you buy 5 liters but don't need that much, take the excess with you. 8. Review the repair bill: Carefully check the settlement list before signing. Keep the receipt as proof of payment. 9. Utilize free inspection services: 4S shops and chain stores often offer free inspections. Periodic checks are essential. 10. Common areas for scams: Three filters (air, fuel, and oil filters) and cleaning services (intake tract, throttle body, and fuel injectors).
I've been driving for many years and never take maintenance lightly. Regular oil and filter changes are crucial—they keep the engine lubricated and cool. Do it every 5,000 km or six months, no delays. Check tire pressure monthly; too low or too high affects grip, and worn-out tires must be replaced—safety first. Don’t ignore brake pads and rotors either; a hissing sound is a warning. Also, maintain coolant and battery levels to prevent overheating in summer and freezing cracks in winter. Clean or replace the air filter often to improve fuel efficiency. Get into the habit of checking these yourself—your car will last longer, saving you money and hassle.
When I first learned to drive, maintenance knowledge was as messy as a tangled ball of yarn. Gradually, I figured out it's actually quite simple. Choose the right oil brand for oil changes, as different cars have different requirements. Check tire tread depth and pressure regularly, and inflate them to prevent blowouts. Don't wait for the warning light to check the brakes. Clean battery terminals to prevent power loss. Replace the air filter in the AC system annually for fresh air and comfort. Also, check lights and wipers routinely for safer night driving. Remember the manual's tips and spend half an hour each month going through them—your car will run much smoother.
