An easy-to-remember guide is: change your car’s oil every 5,000 kilometres or every three to six months. It may sound excessive, but car companies recommend changing the oil frequently to avoid damage. Depending on the type of car you drive and your driving habits, you may need to change the oil less often. Newer engines and high-quality oil may allow you to drive further between changes. Check your owner’s manual or consult a mechanic on the best option for your needs.
