There are many factors that will influence how often your oil needs to be changed. One of those factors is your driving habits. If you are a low-mileage driver, then you will not have to change your oil as often as a person who drives several miles per day. Keep in mind that 40 miles or less is considered low mileage. If you have an older car, then you will still have to change your oil more often than you would if you had a new car.
If you are in doubt about how often you should have the oil changed, then you can look at the owner's manual. You can also ask a mechanic. Regular oil changes will keep your car running at its peak. This is important regardless of how many miles you drive.
