What needs to be replaced for a new car at 30,000 kilometers?

A new car at 30,000 kilometers requires replacement of air filters, cabin air filters, brake fluid, coolant, spark plugs, and other components. Engine oil and oil filter: If using mineral oil, semi-synthetic oil, or full synthetic technology oil, the maintenance interval is generally 5,000 kilometers or six months. For full synthetic oil, the interval is 10,000 kilometers or one year. Replace the engine oil and oil filter, and check the cleanliness of the air filter and cabin air filter. Air filter: Depending on the tire wear, perform a cross-rotation of all four tires. Various fluids: Additionally, at every 40,000 kilometers, it is necessary to replace all vehicle fluids, replace the timing belt/chain, clean the throttle body, fuel injectors, and other components, and inspect the condition of wear items such as brake pads and tires for replacement as needed.

I just drove my new car to 30,000 kilometers and feel that maintenance is quite important. Typically, the most basic tasks include changing the engine oil and oil filter, which are key to ensuring good engine lubrication. For someone like me who drives frequently, the air filter also needs to be replaced as it filters out dust from the intake air, keeping the engine breathing smoothly. If the cabin air filter has been used a lot, it might be dirty and need replacement to keep the air inside the car fresher. It's advisable to check the brake fluid, as some cars may recommend replacement at this mileage to avoid brake failure and potential hazards. Inspect the tires for wear and rotate or replace them if necessary; spark plugs may need replacement in certain performance models. Overall, I follow the manual to avoid saving small money but risking major issues. If the environment is dusty, these maintenance items should be done even earlier. This way, driving becomes more reassuring, and the car's lifespan is extended.

When the new car reaches 30,000 kilometers, I first check the owner's manual for recommendations. The core is changing the engine oil and oil filter, as these two directly affect engine health and can extend its lifespan. The air filter may need replacement if frequently driven in dusty urban areas, but don't overdo it—sometimes cleaning is sufficient. The cabin air filter should be replaced based on usage, typically when there's an unpleasant odor. Other items like brake fluid and spark plugs usually only require inspection at this mileage unless the manual specifies otherwise. Check tire wear and rotate if necessary. DIY filter replacements can save some money; I usually handle them in the garage. Overall, avoid excessive maintenance—stick to essentials for both peace of mind and wallet savings. Regular minor upkeep to prevent major issues is a wise approach.

At 30,000 kilometers, safety comes first. I always change the engine oil and oil filter to ensure smooth engine operation. The air filter is also replaced to prevent dust buildup and maintain respiratory health. Check the brake fluid level and top up or replace if low. Inspect tire treads and rotate them if necessary to balance wear. These simple replacements can prevent major accidents and ensure peace of mind on the road. Timely maintenance is crucial.
