How Many Kilometers Should a Diesel Vehicle Drive Before an Oil Change?

[DeCora]

Every 5,000 kilometers, the engine oil should be changed. Below is relevant information about engine oil: 1. Functions of engine oil: The main functions of engine oil are lubrication, cleaning, and heat dissipation. In fact, many parts of a vehicle use oil, but the oil that needs to be changed every 5,000 kilometers refers to the engine oil. Most people generally use semi-synthetic or fully synthetic oil, while conventional oil is rarely used. Conventional oil is typically used in agricultural machinery, three-wheeled vehicles, and motorcycles. 2. Replacement intervals: Conventional oil should be changed every 5,000 kilometers, semi-synthetic oil every 7,500 kilometers, and fully synthetic oil can go up to 10,000 kilometers before requiring maintenance.
