Spark plugs should be replaced every 20,000KM. Components such as brake fluid and transmission oil are inspection items. The Kia K3 should be serviced every 5,000 kilometers. Below is a detailed introduction to the vehicle maintenance items: Engine Oil and Oil Filter Replacement: This primarily involves maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove various impurities from the oil, ensuring the normal operation of the lubrication system. The oil filter should be replaced along with the oil during an oil change. Under normal circumstances, the car should be serviced every 5,000KM. Filter Element Replacement: The air filter element functions to filter air before it enters the cylinder, removing impurities such as dust, sand, and other foreign particles. The cleaning and maintenance of the air filter element depend on the usage environment. The gasoline filter element is generally replaced after driving 20,000-25,000KM. Spark Plug Replacement: Spark plugs are consumable parts and should be replaced every 20,000KM. Additionally, components such as brake fluid, transmission oil, battery, throttle, fuel injector, and brake pads are all inspection items during routine maintenance, with maintenance performed as needed based on usage conditions.

I've been driving a Kia K3 for three years now. I remember the manual says the maintenance interval is every 7,500 kilometers or 6 months, but as an office worker who often commutes in the city with lots of traffic jams, I change the oil and filter every 5,000 kilometers. Brakes wear out quickly on the road, and checking them can prevent major issues. Oil quality is also crucial—using full synthetic oil is more expensive but offers better durability. Once I got lazy and missed a maintenance period, and the engine started making strange noises, costing me much more to repair—a real loss. I recommend setting a phone alarm reminder to go to a professional shop when you reach the mileage or time—don't cut corners by going to small workshops. Proper maintenance can extend your car's life by over ten years, making driving smoother and saving you money.

As a seasoned driver, I've been using my Kia K3 for almost five years with extensive long-distance experience. Routine maintenance is scheduled every 7,500 kilometers. However, if you rarely drive on highways and frequently travel on bumpy suburban roads, the interval should be shortened to 5,000 kilometers due to the high risk of carbon buildup and wear. During oil changes, always inspect the brake discs and tire treads to avoid safety hazards. Old engine oil can cause overheating, increased fuel consumption, and black smoke emissions. Remember to request a service checklist after each visit to note the next maintenance date and prevent oversight. Maintaining these habits keeps the car in like-new condition, preserving its resale value. Changing the air filter yourself is an easy money-saving trick worth learning.

For us young people driving the new K3, the vehicle's infotainment system comes with a maintenance reminder function set at a default interval of 7,500 kilometers—don't ignore the dashboard indicator light when it illuminates. Smartphones can install the automaker's app to synchronize mileage for accurate interval calculations. Deteriorated engine oil affects emissions and, beyond environmental concerns, weakens engine performance. Regular replacements keep performance optimal; for city driving with frequent traffic jams, a check-up every six months is recommended. Quick-service shops offer efficient maintenance, wrapping up in about half an hour without disrupting travel plans.
