How Often Should Engine Oil Be Changed for Small Cars?

[ReidAnn]

It is recommended to change the engine oil every 5,000 kilometers or once a year for cars. Below are detailed guidelines regarding engine oil changes: 1. For new cars, it is advisable to change the engine oil after driving 3,000 kilometers. The oil change interval can be adjusted based on different driving environments and habits. 2. Mineral oil should be changed within 5,000 kilometers, and the interval should not exceed this mileage. Semi-synthetic oil allows for a slightly extended oil change interval up to 7,500 kilometers, while full synthetic oil can extend up to 10,000 kilometers. The specific interval depends on the type of oil used in the vehicle. 3. There are three types of engine oil: full synthetic, semi-synthetic, and mineral oil. Full synthetic oil should be changed every 10,000 kilometers or once a year; semi-synthetic oil every 7,500 kilometers or every 7-8 months; and mineral oil every 5,000 kilometers or every 6 months. Prolonged failure to change the engine oil can lead to oil degradation, reduced lubrication effectiveness, insufficient lubrication of internal engine components during operation, increased wear of engine parts, and shortened engine lifespan.
