What Maintenance Must Be Done at 50,000 Kilometers for a Car?

[Delaney]

When a car reaches 50,000 kilometers, the following maintenance items should be performed: 1. Essential Items: Replace the engine oil and oil filter. These are mandatory items in every car maintenance session, and both should be replaced simultaneously. Engine oil deteriorates significantly under the high-temperature, high-pressure conditions inside the engine, reducing its protective properties over time. The oil filter prevents impurities from mixing with the oil, which can cause oxidation and lead to sludge formation, potentially clogging the oil passages. 2. Routine Items: Clean or replace the cabin air filter. The cabin air filter's role is to purify air entering the vehicle's interior from the outside, improving air quality. If the filter is not heavily soiled, it can be cleaned from bottom to top using an air gun. If it is very dirty, it's advisable to replace it directly, as it is relatively inexpensive. 3. Routine Items: Replace the spark plugs. If the spark plugs have not been replaced before reaching 50,000 kilometers, it's time to do so. The replacement interval varies depending on the spark plug material, so it's recommended to check the material type of your car's spark plugs before replacement. 4. Routine Items: Replace the tires. Although tire replacement should primarily depend on their wear condition, by the time a vehicle has traveled 50,000 kilometers, the tires are nearing the end of their lifespan. Even if not replaced, regular inspections of the tires' condition are necessary to ensure driving safety.
