How Many Kilometers Should a Car's Engine Oil Be Changed?

[SanFelix]

Generally, a car's engine oil should be changed every 5,000 kilometers. Below are the specific steps for changing the engine oil: 1. Warm up the car before changing the oil: Start the vehicle and let the engine reach normal operating temperature, then turn off the engine. The purpose of warming up the car is to allow the oil to flow fully and carry out impurities. Use a jack to lift the vehicle and engage the handbrake. 2. Drain the old oil: Use the vehicle's tools to loosen the oil drain plug on the oil pan and drain the oil. Be sure to collect the old oil in a container to avoid environmental pollution. Once the oil is completely drained, reinstall the drain plug, being careful not to overtighten it to prevent damage to the oil pan. 3. Install the new oil filter: Use an oil filter wrench to loosen the old filter. Apply new oil to the seal of the new filter, then manually install the new oil filter and tighten it with the tool. 4. Add new oil: Pour the new oil into the oil filler port, using a funnel if necessary. After adding the oil, check for any leaks. If there are no issues, remove the jack and lower the vehicle. Use the dipstick to confirm the oil level, then restart the vehicle to check if any warning lights come on.
