Do you need to use oil on a non stick pan when cook?

Non-stick pans are designed to be used without oil, as they have a special coating that prevents food from sticking. However, some people prefer to use a small amount of oil to help prevent food from sticking, especially when cooking delicate foods like eggs. If you do choose to use oil, be sure to use a high-heat cooking oil such as canola or olive oil. Avoid using butter or margarine, as they can leave a residue on the pan and make it more difficult to clean.
