When Should I Change the Oil for My New Car?
1 Answers
The first oil change for a new car should occur when the mileage reaches between 1,000 to 1,500 kilometers. This mileage range corresponds to the break-in period of the car, which refers to the initial driving phase after purchasing a new car or completing a major overhaul. This period ensures that the components fully contact, friction, adapt, and settle. During this time, the car's parts can adjust and enhance their ability to adapt to the environment, while also wearing down any rough surfaces on the components. Key factors to consider when choosing engine oil: Select engine oil based on the requirements of the engine. There is no need to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Precautions for changing engine oil: The engine must be warmed up before draining the oil. This is because the oil becomes thinner when warm, making it easier to flow and carry away impurities, which helps in completely draining the oil. Never drain the oil when the engine is cold. Additionally, the oil filter should be replaced simultaneously. An old oil filter may become clogged with impurities, slowing down oil flow and reducing engine lubrication. When refilling oil, ensure the quantity is accurate. For some vehicles, the oil level can be checked using the dipstick to determine if it is appropriate. Functions of engine oil: The primary function of engine oil is lubrication. During the lubrication process, the oil is gradually consumed, and impurities and deposits may form, affecting its effectiveness. Engine oil also has a cleaning effect, but some residues may remain in the engine. The anti-rust property of engine oil is crucial as well. While oil cannot completely prevent oxidation, it can reduce it. Good sealing enhances mechanical efficiency, but prolonged use of oil can lead to chemical reactions that weaken sealing. Cooling is another function of engine oil, but its cooling effect diminishes over time with prolonged use.
