Generally, a car should undergo every 5,000 kilometers. More relevant information is as follows: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. 2. Car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life. In addition, consumable parts of the vehicle should also be replaced on time, such as brake pads, wiper blades, tires, belts, batteries, brake fluid, etc.

Based on my driving experience, new cars should have their first after running about 5,000 kilometers or six months in the first year to ensure proper engine break-in. After that, regular maintenance every 7,000-8,000 kilometers or eight months is ideal. My old Toyota has lasted ten years by sticking to this schedule. For those who frequently drive long distances, it's best to check the engine oil and filters before trips, especially in summer when high temperatures can cause oil degradation. Cars parked in garages might extend maintenance intervals by two months, but vehicles parked outdoors require more frequent attention as exposure to wind and rain significantly impacts their condition.

My neighbor, a car mechanic, said that the cycle shouldn't solely rely on the odometer—it's all about how the car is used. His advice is that for regular family cars, a basic service every 8,000 kilometers is reasonable, but vehicles frequently driven on mountain roads or often fully loaded might need an oil change every 5,000 kilometers. He mentioned that many people forget the maintenance manual is the golden standard, with requirements varying greatly between brands. German cars typically require servicing every six months, while some Japanese models can go up to a year. Last time I forgot to change the air filter, my fuel consumption inexplicably increased by 20%.

I've been driving for ride-hailing platforms for over four years, working ten hours daily. The car must go for every 5,000 kilometers, with a focus on checking oil viscosity and brake pad wear. Urban road conditions cause more wear than highways, requiring brake pad replacements twice as frequently as the maintenance manual suggests. The cabin air filter needs changing every two months, otherwise, the car fills with dust odor. Replacing spark plugs every 30,000 kilometers is safest—waiting until issues arise is too late. In areas with frequent rain, extra attention should be paid to wiper blade rubber deterioration.

Last week, I accompanied a friend to buy a , and the dealer repeatedly emphasized checking the maintenance records. He said that for regular cars driven less than 10,000 kilometers annually, at least one maintenance session is necessary to prevent rubber component aging. For cars within two years, follow the manual; for older cars over five years, additional checks for chassis rust and wiring aging are required. Over-maintenance burns money, but skipping maintenance for too long leads to even costlier repairs. I’ve seen cases where transmission oil unchanged for six years led to complete failure—saving small amounts only to suffer greater losses.

My cousin manages over 50 vehicles in the fleet, and they follow strict standards: gasoline cars are serviced every 7,500 kilometers or ten months, while diesel vehicles get an oil change every 5,000 kilometers. The focus is on three key components—engine oil must be replaced if it turns black, brake fluid is changed if water content exceeds 3%, and coolant is replaced immediately if its freezing point is insufficient. They use onboard diagnostics to read data and prioritize maintenance for vehicles with high engine load. He often says spending 800 on maintenance can save 8,000 in repair costs, and emphasizes not neglecting tire rotation and wheel alignment.
