Can you tell me how to change my own car oil?

Changing your own car oil is a relatively simple and straightforward task. Start by gathering all the necessary materials, like an oil filter, a wrench, a drain pan, rags, and the oil. Make sure you have the type and quantity of oil that is right for your car.  Once you’re all set, park your vehicle on an even surface, such as a driveway. Locate the oil drain plug and oil filter. Unscrew the oil plug using your wrench, and allow the old oil to drain into the drain pan. Replace the oil plug and unscrew the oil filter. Place the drain pan beneath the filter, and remove the filter. Finally, replace the filter, pour in the new oil, and recycle the old oil.
