How Many Kilometers Should a Sedan Go Before an Oil Change?

[HeidiFitz]

Sedans should change oil every 5,000 kilometers, semi-synthetic oil every 7,500 kilometers, and fully synthetic oil every 10,000 kilometers. The oil change interval should also be determined based on daily driving conditions, personal driving habits, and time cycles. The first and second maintenance of a new car must strictly follow the time and mileage specified in the car's user manual. If either the time or mileage is reached, the oil should be changed because the initial oil contains a lot of metal debris, which can severely damage sealing components. The functions of engine oil include lubrication, auxiliary cooling, sealing and leak prevention, rust and corrosion prevention, wear reduction, and cleaning of carbon deposits and sludge.
