It is best to replace them to ensure working performance. Therefore, most car maintenance manuals will clearly specify this. This principle is very similar to that of an air filter, so regular replacement is also very necessary. It generally includes cleaning the combustion chamber oil circuit and internal engine cleaning.

When your car hits the 90,000-kilometer mark, it feels like a turning point. This is when many components need careful inspection. I remember with my old car, right after crossing this mileage, I went for an oil and oil filter change—after all, it's recommended every 7,000 to 8,000 kilometers. Don't forget to check the spark plugs; if the car shakes during startup or fuel consumption increases, it might be time for a replacement. The braking system requires special attention—worn brake pads can lead to longer stopping distances, which is dangerous. I also had the mechanic check the tire wear; if the tread is shallow, consider replacing them or doing a wheel balance to prevent skidding. The air filter and cabin air filter should be replaced to ensure good air quality inside the car. Checking the suspension system can reduce strange noises and bumps. Overall, spending a little on these preventive maintenance tasks can save you from major engine repairs or accidents in the future, making driving much more reassuring.

At the 90,000-kilometer maintenance, I always prioritize checking the wear and tear of the vehicle. The viscosity of the engine oil may have thinned and needs to be replaced promptly to prevent accelerated engine wear. If the spark plugs haven’t been replaced, now is a good time—otherwise, poor ignition can affect performance and fuel efficiency. Don’t forget to inspect the brake discs and pads; severe wear can increase braking distance and safety risks. It’s also time to rotate the tires to ensure even wear and extend their lifespan. The belts are another critical point—if they show signs of aging or cracking, replace them to avoid sudden failure and breakdowns. I’d recommend a full computer scan to check for any hidden fault codes. Finally, replace the air filter to keep the engine breathing smoothly. Regular maintenance keeps the car in top condition and saves unnecessary expenses.

When my car reached this mileage, the main maintenance tasks were changing the oil filter to ensure proper lubrication. Checking the spark plugs and ignition system to avoid starting difficulties. The brakes must be inspected carefully, as worn pads can cause noise or even failure. Check the tire pressure and tread wear, as imbalance can lead to skidding. Don't forget to replace the air filter to maintain clean airflow. These basic tasks can prevent major issues, saving money and hassle.
