During car , the following items are generally replaced: engine oil, fuel, transmission fluid, brake fluid, power steering fluid, engine antifreeze coolant, windshield washer fluid, battery water, engine oil filter, air filter, fuel filter, cabin air filter, spark plugs, brake pads and rotors, clutch, wiper blades, sealing strips, timing belt, tires, battery, and other wear-and-tear or consumable items. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle. The purpose is to maintain a clean appearance, normal technical condition, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.

During my last visit, I had a long chat with the technician. The car needs an oil and oil filter change every 5,000 to 10,000 kilometers—just like how the human body needs fresh blood. I replace the air filter about once a year; if it gets clogged, the car can't 'breathe.' The cabin air filter is especially easy to overlook—if there's a musty smell when the AC is on, it's time to replace it. I always take care of it before summer arrives. Brake fluid should be changed every two years or so, as absorbed moisture can affect braking sensitivity. Spark plugs depend on the material—ordinary ones should be replaced at around 30,000 kilometers. I make sure to replace the coolant every three years during major maintenance—it prevents boiling in summer and freezing in winter. Lastly, I recommend checking the transmission fluid and chassis bushings every 60,000 kilometers—these are the keys to keeping the car from aging.

I've summed up some experience when it comes to car . For the first service, just change the engine oil and oil filter. For subsequent services, always check the air filter and replace it if it's dirty. I once delayed replacing the cabin air filter for a year and a half, and the air coming out smelled like dust. Spark plugs are crucial - standard copper ones will definitely wear out at 30,000 km, but iridium ones can last up to 80,000 km. Pay close attention to the braking system; brake pads must be replaced when they get thin. I once waited until I heard metal grinding sounds to replace them and ended up spending an extra 800 to replace the brake discs. Tires age in four to five years - replace them immediately if you see cracks on the sidewalls. Replace wiper blades if they don't clear rain properly. Finally, I remind everyone to follow the maintenance manual and don't get tricked into unnecessary over-maintenance.

As a seasoned driver, I've learned that and part replacements should focus on the essentials. Engine oil and oil filter are the basics, with full synthetic oil capable of lasting 10,000 kilometers. The air filter should be replaced every 20,000 kilometers, and the cabin air filter must be renewed before summer. Spark plugs depend on the material; factory ones should be retired by 50,000 kilometers. Brake fluid should be tested for water content every two years—replace immediately if it exceeds 3%. Don't wait until the coolant turns murky to change it. Transmission fluid should be replaced during the major service at 60,000 kilometers. Keep an eye on the battery around three years; if starting becomes sluggish, prepare to replace it. Wear-and-tear parts like wipers and tires should be replaced based on actual wear—don't compromise safety to save money. Regular minor maintenance is key to avoiding major repairs and is far more cost-effective than waiting for a breakdown.

I categorize part replacements into three levels: Basic items include changing engine oil and oil filter every six months, with the oil filter acting as a barrier against metal debris. Core items involve replacing both air and cabin filters every 20,000 km—change the cabin filter immediately if dirty to prevent bacterial growth. Deep maintenance includes spark plug replacement at 40,000 km, transmission fluid at 60,000 km, and brake fluid changes determined by a moisture tester. For wear-and-tear parts like wiper blades and tires, I stock up during 618 and Double 11 sales, saving half compared to emergency replacements. Pay special attention to chassis bushings and engine belts—check for cracks during car washes, as sudden failure of these aged components can cause serious trouble.

Just like humans, cars need regular check-ups. During , I insist on replacing these: engine oil and oil filter are equivalent to a blood change, the air filter is the engine's mask—replace it when dirty. The cabin air filter is crucial for respiratory health and must be replaced before the rainy season. Brake system maintenance is the most non-negotiable; replace brake fluid immediately if its water content exceeds standards. I opt for platinum spark plugs, changing them every 50,000 kilometers for peace of mind. Coolant should be completely replaced every three years, as mixing can cause chemical reactions. Among consumables, I pay special attention to battery life—prepare a new one if voltage drops below 12V. Lastly, I recommend checking tire pressure and lighting systems during every maintenance; these active safety components are too important to overlook.
