What maintenance is required at 20,000 kilometers for a car?
2 Answers
Maintenance at 20,000 kilometers primarily includes replacing the engine oil, oil filter, spark plugs, cabin air filter, and engine air filter. Oil and oil filter changes are essential biannual services, as their performance degrades and shelf life significantly shortens under high-temperature and high-pressure conditions. The oil filter mainly prevents impurities from entering the oil and forming sludge that could clog the oil passages. Car maintenance, also known as vehicle servicing, refers to the periodic inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain components as preventive measures. Its purpose is to maintain the vehicle's appearance, ensure normal technical conditions, eliminate potential hazards, prevent malfunctions, and extend the vehicle's service life.
I remember when my car reached 20,000 kilometers, the maintenance was done quite thoroughly. Generally speaking, changing the engine oil and oil filter is the most critical, as it ensures good engine lubrication, smooth driving, and better fuel efficiency. I also checked the tire wear and pressure to make sure there was no uneven wear, since a blowout on the highway can be very dangerous. The air filter should be replaced if it's too dusty, otherwise the engine won't get enough clean air, which affects performance. I didn’t overlook the braking system either—inspecting the brake discs and pads to avoid failure in emergencies. Additionally, I checked the lights, battery, and coolant level while I was at it. A full check-up in advance helps the car last longer. Experience tells me that regular maintenance not only saves money but also keeps the car out of the repair shop.
