Typically, a minor maintenance is performed every 7,000 kilometers or so, while a major maintenance is done around 14,000 kilometers, but this depends on the specific condition of the vehicle. Below is more relevant information: 1. Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle upkeep. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent malfunctions, slow down deterioration, and extend the usage cycle. 2. Car maintenance is divided into major and minor maintenance. In addition to changing the engine oil, major maintenance also involves replacing the three filters and spark plugs. The three filters refer to the air filter, oil filter, and fuel filter. The filters function to remove impurities, with each filtering dust from the air, sludge and carbon deposits from the oil, and impurities from the fuel, respectively. 3. Minor maintenance generally refers to routine maintenance tasks performed when the vehicle hasn't traveled long distances to ensure its performance, mainly including changing the engine oil, oil filter, and conducting routine inspections.

From my driving experience, minor maintenance is usually done every 5,000 to 10,000 kilometers, or every six months, depending on the condition of the car. If you're driving a new car, the mileage suggested in the manual is the most reliable. My first car was a hassle—I pushed it to 10,000 kilometers without maintenance, and the engine developed minor issues, costing me over a thousand dollars to fix. Later, I realized that if you drive mostly in city traffic with frequent congestion, it's better to do it earlier, changing the oil and oil filter within 5,000 kilometers. If you drive more on highways, you can stretch it to around 8,000 kilometers. Minor maintenance not only extends engine life but also improves fuel efficiency. Neglecting it can lead to sludge buildup, accelerating part wear, and risking a breakdown on the road, which is dangerous. Nowadays, cars have electronic warning lights, but don’t rely solely on them—regularly checking the manual or an app record is more reassuring. Remember, extreme temperatures also affect oil performance, so in northern winters, it’s best to shorten the interval for safety. Overall, developing a maintenance habit is the most cost-effective approach—don’t wait until something breaks to take action.

As an experienced driver, let me share my perspective: With 20 years of driving under my belt, the frequency of minor maintenance truly depends on driving habits. For frequent short trips or heavy traffic conditions where engine oil degrades faster, I recommend checking and changing the oil every 6,000 km. For smooth long-distance highway driving, 10,000 km intervals are acceptable. From my experience, skipping one maintenance session led to a clogged oil filter and subsequent engine repairs – costly and time-consuming. Modern vehicles using full synthetic oil can extend intervals to around 8,000 km, but always prioritize the manufacturer's manual over verbal advice. In areas with poor fuel quality, consider earlier maintenance; my hometown's dusty environment caused abnormal noises when maintenance was slightly delayed. Regular minor maintenance protects the entire drivetrain, prevents major repair risks, and is crucial for safety.

As a new car owner, I usually do a minor maintenance every 7,000 kilometers. The vehicle's system reminds me when it's time for an oil change, which is quite handy. Basic maintenance includes changing the engine oil and oil filter—it doesn't cost much but is crucial: a smooth engine saves fuel and extends the car's lifespan. I recommend beginners check the manual first; for example, with my hybrid car, the interval can extend to 10,000 kilometers. Skipping regular maintenance can easily trigger warning lights, leading to troublesome repairs. Don’t forget to adjust based on road conditions—dusty areas require more frequent maintenance.
