How Many Kilometers Should 0W40 Engine Oil Be Replaced?
2 Answers
It is recommended to replace it every 5,000 kilometers or three months. The meaning of 0W40 engine oil: The 0W in 0W40 indicates the cold-start performance of the engine oil. Using engine oil with a lower value before the W makes it easier to start the engine in cold weather. Below is the relevant introduction: Engine oil replacement intervals for different cars: Mineral oil should be replaced every six months or 5,000 kilometers, semi-synthetic oil every six months or 7,500 kilometers, and full synthetic oil every six months or 10,000 kilometers. New cars should strictly follow the maintenance intervals specified in the manual to avoid serious damage. Precautions for changing engine oil in new cars: The amount of engine oil added should be appropriate, as indicated by the dipstick. After adding the engine oil, start the engine and check for any leaks in the components. After starting the engine, run it for 3 minutes and check the engine oil level again. When the oil level reaches the normal mark and there are no leaks, reset the maintenance light, and the oil change is complete.
As an ordinary driver with over a decade of experience, I understand the importance of the 0w40 oil change interval. Generally, manufacturers recommend changing it every 8,000 to 12,000 kilometers, but it depends on your driving habits and environment. My own car mostly drives in congested urban areas with poor road conditions and heavy dust, so the oil gets dirty faster, prompting me to check and change it at 7,500 kilometers. The key is not to delay—inspect the oil level and color during each maintenance. If it's too dark, change it immediately. 0w40 has low viscosity and excellent low-temperature fluidity, making it suitable for northern winters, but its high-temperature protection is weaker, so extra attention is needed in summer. Regular oil changes protect the engine, extend its lifespan, and save you from costly overhauls. Always refer to the vehicle manual—don’t just rely on others’ advice.
