What maintenance should be done at over 50,000 kilometers?

A vehicle reaching 50,000 kilometers requires major maintenance, which includes replacing the engine oil, oil filter, air filter, cabin air filter, fuel filter, spark plugs, and belts, as well as inspecting the chassis, brake pads, brake discs, tires, and other components. Below are the detailed steps: 1. Replacing the engine oil and oil filter is a mandatory task for every maintenance service. Under the high-temperature and high-pressure conditions inside the engine, the shelf life of engine oil is significantly shortened, and its performance degrades considerably. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing with the oil, which can cause oxidation, leading to sludge and clogging the oil passages. Both the engine oil and oil filter should be replaced simultaneously. The air filter should be replaced every 10,000 to 15,000 kilometers. 2. The replacement interval for spark plugs depends on their material. Generally, spark plugs should be replaced every 2 to 4 years. Even if spark plugs haven't completely failed, degraded ignition performance can directly impact the vehicle's power and fuel efficiency. 3. If the cabin air filter hasn't been replaced for a while, it should also be replaced. The cabin air filter functions similarly to the air filter, ensuring clean air inside the car when the air conditioning is on. Therefore, it should be replaced periodically. If you notice odors or excessive dust blowing from the vents when using the air conditioning, the cabin air filter should be replaced immediately. 4. Components such as brake pads, tires, and the battery may also need replacement if they haven't been changed before. At the 50,000-kilometer maintenance, it's advisable to replace them if necessary.
My car just passed the 50,000-kilometer mark, and I'm in the habit of doing a systematic maintenance to ensure it continues to run smoothly. First, change the engine oil and oil filter, which typically need replacement every six months or 10,000 kilometers, as oil degradation and impurity buildup directly affect engine lifespan. Check the air filter and cabin air filter—if they're clogged, it can impact air intake efficiency and cabin air quality, potentially leading to increased fuel consumption or odor issues. The braking system shouldn't be overlooked, especially inspecting the thickness of brake pads and rotors, as excessive wear can increase stopping distance risks. Tire rotation and balancing are critical for safety, ensuring even wear and extended tire life. The spark plugs should also be replaced; delayed ignition can cause engine misfires or power loss. Additionally, check and replace the coolant to prevent overheating failures. Maintenance may cost a few hundred yuan, but neglecting it could lead to major repairs—I recommend visiting a trusted repair shop for a thorough service. Regular upkeep saves money and hassle in the long run.
I remember when my car hit the 50,000-kilometer mark, I thought it was time for some maintenance. Changing the oil filter was a basic operation, and I asked the mechanic to check for oil buildup, as too much grime can make the engine sound louder. I paid special attention to the brake system, checking the thickness of the brake pads—replacing them early if they were worn out gave me peace of mind, as brake failure during an emergency stop would be troublesome. I also requested a tire rotation since uneven wear occurs over time, and adjusting their positions can extend their lifespan. Replacing the spark plugs at this point was ideal, as old ones cause poor ignition and noticeable jerking while driving. After changing the air filter, I felt the airflow became much fresher. Although maintenance costs some money, it prevents sudden breakdowns. I always note the mileage for these small tasks, as developing good habits keeps the car running longer.
