You may have been told that you should change your oil once every three months. However, that rule only applies to high-mileage driver. You will not have to change your oil that often if you are a low mileage driver. This means that you only drive 7,500 miles or less per year. It is equivalent to about 40 miles or less per day.
You can find the general recommendation in your owner's manual. It is important to follow the mileage recommendations for oil changes regardless of whether you are a high or low mileage driver. This means that if it takes you six months to reach the 5,000 mark, then this is when you will need to get the oil changed. Regular oil changes are necessary for keeping your vehicle functioning properly. The oil will degrade in quality even if you don't drive your car frequently.
