Car items include: 1. Changing the engine oil and oil filter; 2. Air filter; 3. Fuel filter; 4. Transmission fluid; 5. Tire maintenance. Below is additional information on car maintenance: 1. Major maintenance builds upon regular maintenance, requiring the replacement of the air filter and fuel filter in addition to the engine oil and oil filter. 2. Major maintenance and regular maintenance can be alternated, with intervals varying by car brand, and should follow the manufacturer's recommendations. Engine oil is the lubricant for the engine, and to ensure optimal performance, it should be replaced periodically. The replacement cycle depends on the oil's effective lifespan. During operation, the engine draws in a large amount of air, and the dust in the air can accelerate wear on the piston group and cylinder. The air filter's role is to remove dust and particles from the air, ensuring that sufficient and clean air enters the cylinder.

I've been driving for ten years and always keep an eye on every session. Changing the engine oil and filter is the most basic task—otherwise, the engine would be like drinking dirty water. Tires need to be checked for wear and pressure, and don’t forget to inspect the spare tire as well. Brake pad thickness is crucial; if they’re too thin and start squeaking, it’s dangerous. The cabin air filter is especially easy to overlook, but replacing it in spring instantly freshens up the air inside the car. Checking the lights is essential for nighttime driving safety—I once saw a loose bulb nearly cause an accident. The mechanic also tests the battery life; catching a failing battery early once saved me from major trouble. Getting all these items done ensures a worry-free and confident drive.

Having worked in an auto repair shop for eight years, I can say that routine essentially boils down to three major areas. For the mechanical section, it's mandatory to check the engine oil condition and replace the three filters (air, oil, and fuel), while the engine compartment requires carbon deposit cleaning. The chassis system focuses on inspecting brake fluid lines for leaks, checking the steering gear for abnormal noises, and assessing ball joint wear. Electrical equipment demands testing the battery voltage and examining all vehicle lighting circuits, especially the fog light connectors which are prone to oxidation. Many consider tire rotation and four-wheel alignment optional, but uneven tire wear and alignment issues are direct consequences of neglecting these services. It's advisable to check coolant levels quarterly, with special attention to antifreeze concentration in southern regions.

When I first bought the car, I was clueless too, but now I've got the hang of it. A minor service is just changing the engine oil and oil filter, like giving the car fresh milk. A major service involves replacing spark plugs, transmission fluid, and the like. Checking the brake pad thickness is a must every time—the way the mechanic measures it with calipers looks super professional. Tires must be replaced when the tread depth goes below 2mm; a mechanic taught me this once while fixing a punctured tire. Replacing the air filter is simple but crucial, especially in dusty places like Beijing. Many people wait until their wipers can't clean properly before replacing them, but checking the rubber strips for cracks during can actually prevent sudden failures.

Just had the done last week, and the items on the receipt were clearly listed. The basic items like oil and oil filter replacement are fixed and included in the labor cost. The mechanic was really cool using the computer to read fault codes, even detecting a door sensor malfunction. During the chassis inspection, the car was lifted high to check for underbody damage, and my SUV was found to have a deformed exhaust pipe bracket. The battery tester showed the remaining lifespan, which gave a warning last winter when the battery was low. An extra throttle valve cleaning was added, and when taken apart, the carbon buildup looked like soot from a pot. Now, after maintenance at the 4S shop, they even wash the car, with the interior vacuuming done very meticulously.

I remember my palms sweating the first time I entered the repair shop, but now I can chat with the mechanics about technical details. Among routine items, transmission fluid must be changed at 60,000 kilometers, otherwise gear shifts will become jerky; brake fluid should be replaced every two years, as excessive moisture content affects braking distance. Many people skip air conditioning duct sterilization, only to be greeted by a foul sour smell when turning on the AC in summer. Repairing the underbody armor is essential, especially for vehicles frequently driven on rough roads. Always insist on a road test before taking delivery—I once detected steering wheel vibrations during a test drive, which led to a wheel balance correction. It’s advisable to bring your maintenance manual, as it lists all mandatory service items by mileage, helping you avoid unnecessary upsells.
