What items need to be replaced during a 20,000 km maintenance?

For a 20,000 km vehicle maintenance, it is necessary to replace the engine oil, oil filter, air filter, cabin air filter, and spark plugs. Below are the detailed explanations: 1. Replacement of engine oil and oil filter Reason: Replacing engine oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance greatly declines. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. Engine oil and the oil filter should be replaced simultaneously. 2. Replacement of the air filter Reason: The air filter's function is to block dust and particles inhaled during the engine's intake process. If the filter is not cleaned for a long time, dust can enter the engine, causing abnormal wear on the cylinder walls. If it was not replaced during the 10,000 km maintenance, it must be replaced at the 20,000 km maintenance. 3. Replacement of spark plugs Reason: If the vehicle uses standard material spark plugs, preparations should be made to replace them at 20,000 km. Spark plugs directly affect the engine's acceleration performance and fuel consumption. If you feel the engine lacks power during driving, maintenance should be performed.

I just completed the 20,000 km maintenance, which mainly involved changing the engine oil, oil filter, and air filter. This is because engine oil gets dirty over time, reducing its lubrication effectiveness and increasing engine wear. A clogged oil filter can be even worse, potentially causing overheating issues. Excessive dust accumulation in the air filter affects air intake efficiency, leading to reduced power and increased fuel consumption. The air conditioning filter was also checked during the process, and it should be replaced if the in-car air quality deteriorates. The whole process reminded me of the importance of maintenance. Timely replacement of these components can extend the engine's lifespan and prevent breakdowns on the road. Remember not to skimp on these costs, and pay attention to driving habits, such as avoiding prolonged idling, to reduce component stress.

I think the most essential replacements during the 20,000 km maintenance are those filter components. Typically, changing the engine oil and oil filter is fundamental to ensure smooth engine operation. Not replacing the air filter would allow dust to enter and damage the cylinders, which isn't cost-effective. Additionally, consider replacing the cabin air filter based on the situation, especially when there's an odor when using the AC. To save money, other parts like spark plugs or brake pads might not need replacement at this stage, but the technician will check for wear and decide. The overall maintenance cost isn't high, yet it prevents major issues—it's like giving the car's heart a regular cleanup. You can also learn some basic knowledge yourself, such as how to tell when the air filter is dirty, to better determine the right time for replacement.

Safety first, the 20,000 km maintenance must include changing the engine oil, oil filter, and air filter. Insufficient lubrication from old oil can increase friction and raise the risk of accidents; a clogged filter affects air supply, potentially causing the engine to stall suddenly. It's recommended to also have the shop check the cabin air filter and tire wear. Although most cars don't have a mandatory replacement schedule for the cabin air filter, accumulated dust can impact health, making it worth attention. Remember, never overlook these small details during every maintenance session—peace of mind comes with a smoothly running car.
