Generally, the maintenance mileage for domestic cars is 7,000 kilometers for minor maintenance, which mainly includes changing the engine oil, inspecting the steering system, lights, brake fluid, and cleaning the three filters. Around 14,000 kilometers, a major maintenance is required. Below are additional details: The main maintenance tasks include changing the engine oil, inspecting the steering system, replacing brake pads, and changing the three filters. Of course, different cars have different maintenance mileage requirements; some require maintenance at intervals shorter than 7,000 kilometers, while others may exceed 7,000 kilometers. Detailed information can be found in the car's manual.

As a long-time car owner, I've driven many vehicles, and the maintenance intervals typically range from 5,000 to 10,000 kilometers, depending on the car model and usage. New car manuals usually specify the recommended intervals—Japanese brands like Toyota and Honda mostly suggest 5,000 km, while European models like BMW and Mercedes can often go up to 10,000 km or longer. This is mainly due to differences in oil and filter performance, with some cars using synthetic oil for greater durability. But don’t forget that driving habits play a big role—for example, I often drive on highways, so I extend the interval, but if you frequently face city traffic jams or take short trips, it’s best to shorten it to around 5,000 km to avoid engine carbon buildup. From an economic perspective, sticking to the schedule saves money in the long run, as skipping maintenance leads to costlier repairs. I recommend checking the manual or consulting a professional shop to keep your car in good health.

From a technical perspective, there's no fixed standard for maintenance mileage intervals as they're driven by multiple factors. Engine type is crucial - turbocharged vehicles may require oil changes every 5,000 km, while naturally aspirated engines can often go beyond 8,000 km. Driving environment also plays a role: dusty or off-road conditions demand shorter intervals, and frequent idling accelerates oil degradation. Additionally, maintenance items like filter replacements and brake system inspections affect the mileage schedule. I recommend combining manufacturer guidelines with usage scenarios. Neglecting maintenance leads to accelerated engine wear - saving small amounts now may result in major repairs later. Based on experience, it's advisable to conduct inspections approximately every 7,000 km for optimal safety and convenience.

Maintenance intervals vary by car. Mine is a hybrid, and the manual says 10,000 km. German cars like Volkswagen and Audi may require 8,000-10,000 km, while Korean cars like Hyundai and Kia mostly need 5,000 km. For older cars, it's recommended to shorten the interval to 4,000-6,000 km to prevent failures. Remember, engine oil is key—synthetic oil extends both mileage and time. Simply put, refer to the manual and don't neglect it.
