What Needs to Be Replaced During the First Car Maintenance?
3 Answers
What needs to be replaced during the first car maintenance includes: 1. Under normal driving conditions, conventional mineral oil should be replaced every 5,000 kilometers on average, semi-synthetic oil every 7,000 kilometers, and full-synthetic oil every 10,000 kilometers; 2. The oil filter, also known as the oil grid, is used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the oil to protect the engine. Both passenger cars and commercial vehicles should replace it every six months; 3. The air filter should be replaced every 15,000 kilometers. For vehicles frequently operating in harsh environments (such as deserts, construction sites, etc.), it should be replaced no more than every 10,000 kilometers. The service life of an air filter is 30,000 kilometers for passenger cars and 80,000 kilometers for commercial vehicles.
Every time I help friends inquire about the first maintenance, I emphasize that the key is changing the engine oil and oil filter. After driving a new car for a while, engine break-in produces debris, and fresh oil can clean these out, making the engine run smoother. Usually, the air filter is also changed around 5,000 kilometers, but you should check the manual as some cars don't require it. Technicians will check tire pressure, brake wear, and light brightness for free to ensure safe driving. I've noticed many beginners think they need to replace all car parts, but don't worry—just doing the basics saves money and is effective. I recommend booking an appointment with the 4S store in advance and keeping a record of maintenance history to avoid hassle in case of warranty issues. The habit of regular maintenance starts here, and the car can last several more years.
As a car enthusiast, I understand that the first maintenance mainly involves changing the engine oil and oil filter. The engine oil protects the engine by reducing friction, while the oil filter blocks impurities to prevent oil passage clogging. Replacing the old oil at 5,000 kilometers is essential to avoid long-term accumulation that could damage the engine. Additionally, checking the coolant level and brake fluid pressure is crucial, as these small details ensure driving safety. I also inspect tire tread depth and may apply an anti-rust coating to the chassis. Don’t be fooled into adding extra services; the air filter usually doesn’t need replacement unless it’s extremely dirty. Develop a habit of keeping your own maintenance schedule to easily track changes in your car’s condition over time.
