How many kilometers can a car still drive after the maintenance period has passed?

The car can still drive one or two thousand kilometers after the maintenance period. Here is the relevant introduction about car maintenance: 1. Primary maintenance: Primary maintenance is a maintenance operation centered on tightening and lubricating motor vehicles that have traveled a certain mileage, including checking and tightening the bolts and nuts of exposed parts of the car; adding lubricants to the designated lubrication parts; checking the lubricating oil level in each assembly and adding lubricating oil; cleaning various air filters, etc. 2. Maintenance scope: In addition to the primary maintenance tasks, check and adjust the working conditions of the engine and electrical equipment, disassemble and clean the oil pan and oil filter, check and adjust the steering and braking mechanisms, disassemble and clean the front and rear hub bearings; add lubricating oil, disassemble and inspect the tires, and perform tire rotation, etc.

There's no definitive answer to how many kilometers a car can go beyond its maintenance interval—it really depends on the specific condition of the vehicle. As someone who drives frequently and has helped friends with car repairs, my experience suggests it's best not to delay too long. For newer cars or those in good condition, driving an extra 500 to 1,000 kilometers might be fine, but aged engine oil increases friction, raises fuel consumption, and may even cause black smoke. Regularly check the dipstick: if the oil appears black or contains metal particles, it indicates severe internal wear. I recommend scheduling maintenance checks promptly, especially for the braking system and filters, as delays can compromise driving safety. A breakdown at highway speeds would be far more dangerous.

As an experienced driver with decades behind the wheel, I occasionally delay maintenance but always keep it within 500 kilometers. Years of driving have taught me that engine oil's lubricating performance deteriorates rapidly after expiration, leading to increased carbon buildup inside the engine. Prolonged driving with expired oil risks cylinder scoring or seizure. I've seen one vehicle run nearly 1,000 kilometers without issues, while another failed after just 200-300 kilometers - this varies by vehicle model and driving habits. The key takeaway: don't gamble with maintenance. Regularly check tire pressure and brake responsiveness to ensure safe travels.

Driving beyond the maintenance period poses significant risks, and I don't have a fixed mileage recommendation. The key is to assess the vehicle's condition. If the oil is fresh and the lights are functioning properly, driving an extra 100-200 kilometers might be acceptable. However, delaying maintenance will accelerate engine wear and increase fuel consumption and emission issues. Safety comes first—it's advisable to schedule a service as soon as possible without delay. Be attentive to any unusual noises or vibrations while driving.
