What maintenance does a car with 30,000 kilometers need?

A car with 30,000 kilometers needs maintenance such as engine oil, oil filter, air filter, fuel filter, throttle cleaning, spark plug replacement, etc. Some 4S shops may require other maintenance items, which can be considered and performed according to the actual situation. Engine oil and oil filter replacement are essential items for 30,000-kilometer maintenance, as engine oil deteriorates significantly under the high-temperature and high-pressure conditions inside the engine, reducing its protective properties over time. Car maintenance, also known as car servicing, refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car.

My car just hit 30,000 kilometers, so I promptly went for a comprehensive maintenance service. An oil change was mandatory – last time after prolonged driving, the engine started vibrating slightly, so I replaced both the oil filter and engine oil, and immediately felt the throttle response became much crisper. Tire inspection couldn’t be skipped either; the mechanic performed wheel balancing for me to check for uneven wear patterns to prevent potential blowout risks. They measured the brake pad thickness and replaced the brake fluid too – safety always comes first. A clogged air filter would affect AC efficiency, so I had that replaced as well, and now the cabin air feels fresher when driving. The spark plugs and coolant were also tested – while 30,000 km isn’t considered old for a car, it’s wise to address minor issues early. I’d recommend regularly consulting the manual, as some models require transmission fluid replacement at this mileage. Coolant can degrade over time, and neglecting it might lead to overheating breakdowns. I’ve learned a lot – nowadays I always check tire pressure and lights before driving to prevent small issues from escalating into major troubles.

My car frequently goes on long-distance trips, and the 30,000-kilometer maintenance is a critical milestone. I prioritized changing the engine oil and filters to protect lubrication and extend the engine's lifespan. Tire pressure was adjusted for balance to avoid abnormal wear and ensure safe driving. The brake system inspection was the top priority—brake pads were replaced if too thin, and fluid levels were accurately measured to guarantee emergency stopping power. The air filter affects fuel efficiency and performance, so I proactively replaced it for a simple yet effective boost. Coolant checks are also essential to prevent overheating issues. At 30,000 km, it's also wise to inspect spark plugs and transmission fluid, as some vehicle manuals recommend replacement. Developing good maintenance habits saves on repair costs and provides peace of mind.

For our family car's 30,000-kilometer major maintenance, I took my child along. We replaced the oil filter to keep the engine healthy. The tire wear was carefully inspected to ensure no bulges or cracks, prioritizing road safety. The brake fluid and brake pads were measured for thickness to prevent accidents. The clogged air filter was replaced by myself, resulting in much better performance. A simple voltage test was done on the battery to prevent starting difficulties. The coolant level was topped up, and the spark plugs were checked for aging. In short, timely maintenance keeps the car running smoothly, making it more reassuring for family transportation.

I always do DIY car maintenance. At 30,000 kilometers, I changed the engine oil and oil filter—an easy job that saves money and is practical. I checked the tire pressure and wear, and did the tire rotation myself, as balance is crucial. I measured the brake pad thickness with calipers and replaced them, saving on shop labor costs. The air filter was bought online and replaced, which is cost-effective with good results. I checked the spark plug gap and left them as is since there were no major issues. A reminder to everyone: coolant boiling point needs professional equipment to test, so I took it to a shop since I don't have the tools. Brake fluid was also tested for moisture—safety first. DIY is fun but time-consuming; beginners shouldn't attempt it lightly and should seek guidance from experienced hands.
