To change your oil you need to put some sort of cleaner first. Once you put the oil cleaner, you turn your car on and leave it running for 10 to 5 min. Then you take out the filter which most of the time is located under the car in the middle. Next you put the oil catcher underneath the place where you take out the filter. You have to let run ( the process is done with the car off). After you do that put in a new filter and put in clean new oil, when you do that let the car run for 5min. When you are cleaning up, put the used oil in the empty oil container and go to the nearest autozone and leave it next to the trash can.
