Typically, a minor car maintenance is recommended every 5,000 kilometers. Many domestic car owners follow the advice of 4S dealerships to perform routine maintenance every 5,000 kilometers or every six months. This usually involves changing the engine oil, oil filter, and air filter. The engine oil should be changed every 1,000 kilometers as it nears its usage limit, with reduced lubrication and viscosity, which can no longer effectively lubricate the engine, potentially affecting its lifespan. Car maintenance, also known as car servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle.

When I first bought my new car, I didn’t know much about maintenance, so I consulted a friend at the 4S dealership. They said that minor maintenance, like changing the engine oil and filters, is typically recommended every 5,000 to 10,000 kilometers. Since my compact car is for family use and mostly driven in city traffic with frequent congestion, I get it checked every 7,500 kilometers. Skipping regular maintenance can lead to carbon buildup and engine wear, which could cause major repair issues later. By the way, recommendations vary by brand—for example, Japanese car manuals often suggest 5,000 km, while some German brands mention 10,000 km—it largely depends on driving habits and conditions. During hot or cold seasons, they also remind you to check the coolant during maintenance to prevent overheating. Now, I’ve developed a habit of tracking it with a mobile app that alerts me about mileage—safety first and cost-saving too. Don’t wait until the car breaks down to regret it.

We have an old family car that's been in use for many years, mainly for school runs and grocery shopping. Minor maintenance is typically done every 6,000 kilometers or so. A knowledgeable mechanic advised us to regularly change the engine oil and air filters, as frequent starts and stops in urban driving cause faster wear, so it's better to do it earlier. Our car's manual recommends maintenance every 8,000 kilometers, but for safety and convenience, we stick to the 6,000-kilometer interval. During maintenance visits, we also have the brake fluid and tire pressure checked. Given the car's age, we've shortened the maintenance intervals to prevent dirty oil from affecting engine performance and avoid costly major repairs. We've also developed the habit of checking the oil dipstick monthly to spot any contamination or deterioration early and prevent potential issues.

I've talked to mechanics about this before. They said the interval for minor maintenance is usually between 5,000 to 10,000 kilometers, depending on the vehicle's condition. For new cars or gasoline vehicles, you might follow the manual's recommendation of 7,500 kilometers, while older cars or those frequently driven on mountain roads should change the oil and filter every 5,000 kilometers. A simpler approach: if you usually drive on smooth roads, you can extend the maintenance interval to 8,000 kilometers, but check the oil color weekly to see if it's turning black. Don't delay too long to avoid increased engine wear and higher fuel consumption. It's recommended that car owners adjust flexibly based on their vehicle model to save money conveniently.

After driving for over a decade, I've concluded that getting a minor service every 7,000 kilometers or so offers the best value. Doing it too frequently, like every 3,000 kilometers, is a waste of money and bad for the environment, while waiting too long, say 12,000 kilometers, increases the risk of car trouble. The key is changing the oil and filter, with higher-quality synthetic oil lasting up to 10,000 kilometers, saving you some expense. Adjusting your driving habits—avoiding rapid acceleration and hard braking—can extend the service interval. Buying parts and replacing the filter yourself saves money, but it's more reliable to have a professional change the oil. Regular maintenance not only prevents major repairs but also improves fuel efficiency, saving you money on gas and letting you enjoy life more.
