i do it myself, always have on all my cars. if you do it yourself, id recommend the following oil plug linked below. you can turn the blue knurled part to slowly drain the oil without removing the entire plug. if you remove the entire plug right away, the oil will drain very quickly and you will likely make a gigantic mess that will take awhile to clean up. ask me how i know... drain it slowly by opening the blue part and once the oil is fully drained, you may remove the entire plug and check the magnetic tip to see what (hopefully none, or very minimal) metal is on it. trust me, the extra few minutes it takes letting it drain slowly is a far better alternative to cleaning up several quarts from your driveway or garage. just keep track of the rubber plug and dont lose it.
