What is the optimal mileage interval for car maintenance?

[Denise]

Generally, cars should undergo maintenance every 5,000 kilometers. Below are relevant details: 1. Maintenance content: The basic service includes engine oil and filter replacement. The oil change interval varies depending on the oil type selected by the owner. Typically, conventional mineral oil requires replacement every six months or 5,000 km, semi-synthetic oil every eight months or 7,500 km, while full synthetic oil can last one year or 10,000 km. 2. Precautions: Vehicle maintenance isn't limited to oil changes. It also involves replacing filters or other components identified during inspection, such as air filters, cabin air filters, spark plugs, etc. These items should follow recommended replacement cycles and shouldn't be affected by extended oil change intervals.
