How Often Should You Change Your Car's Engine Oil?

[DawsonLynn]

Here is an introduction about how often to change your car's engine oil: 1. The mileage or time interval for changing engine oil is generally based on the recommendations in the vehicle's user manual, which is typically 5,000 kilometers or 6 months, whichever comes first. You can also appropriately adjust the oil change interval based on usage conditions or other factors to accommodate different operating conditions. This ensures good engine lubrication and extends the engine's service life. 2. Synthetic oil should be changed every 7,000-10,000 kilometers, while mineral oil needs replacement around every 5,000 kilometers. If a car is not maintained and the oil is not changed, it can clog the oil passages, leading to dry friction between parts and causing burning or corrosion. When the car is running, engine oil plays a cleaning role by smoothing out the contact between parts as they rub against each other, grinding down uneven surfaces, and carrying away debris into the oil.
