What are the maintenance items?

Regular maintenance includes minor maintenance and major maintenance. The following are the specific introductions to maintenance: 1. 10,000-kilometer maintenance: Basic maintenance, commonly known as "minor maintenance," is required every 10,000 kilometers. The maintenance items include two: engine oil and oil filter. 2. 20,000-kilometer maintenance: 20,000-kilometer maintenance, commonly known as "major maintenance," requires replacing the oil filter and engine oil, as well as the cabin air filter and spark plugs. 3. 40,000-kilometer maintenance: The maintenance items for every 40,000 kilometers are more than those for 20,000 kilometers. In addition to engine oil, oil filter, cabin air filter, and spark plugs, the air filter and brake fluid also need to be replaced.
I've got experience with maintenance. Here's what I focus on: Engine oil and filter must be changed every time - poor changes will make the engine suffer. The air filter is like the car's mask - when dirty it affects breathing efficiency and increases fuel consumption. The cabin air filter affects air quality, so I replace it myself every other year. As for spark plugs, the manual says replace at 40,000 km, but I change them at 30,000 km. I check tire pressure and wear every month, and have mechanics measure brake pad thickness with calipers. The most commonly overlooked are fluids - brake fluid with high water content reduces braking power, and failed coolant can cause overheating. Oh, and after each service I write the next maintenance date on the windshield sticker so I won't forget!
I categorize maintenance into three levels. Basic maintenance includes oil and the three filters, done every 5,000-10,000 kilometers; intermediate maintenance adds transmission fluid and brake system checks; major maintenance involves core components like timing belts and spark plugs. For DIY tasks, I check the oil dipstick every two weeks, top up windshield fluid as needed, and measure tire pressure monthly. At the dealership, they use diagnostic tools to read computer data—last time, they detected a weak oxygen sensor signal and replaced it early. I change brake fluid every two years without fail, especially in humid southern regions where it absorbs moisture more easily. Tightening chassis bolts is crucial as vibrations can loosen them. Keeping a detailed maintenance log in the handbook is recommended—it boosts resale value for used cars.
To put it simply, there are three categories: mandatory oil and oil filter changes; recommended air filter and fuel filter replacements; and discretionary services like throttle body cleaning and wheel alignment. I regularly check the brake pad thickness and replace them immediately if they're below 3mm. Listening to the engine sound during cold starts can help determine the oil condition. During maintenance, special attention is paid to chassis inspection, as worn ball joint boots can cause abnormal noises. Last time, I found a torn CV boot leaking grease, but thankfully it was replaced in time to avoid major repairs. Pouring hot water over the battery terminals to remove white crystals can extend battery life. Don't wait until the wiper blades are completely ineffective before replacing them.
