The video is an engine with straight down drain plug so it is a clean drain. I saw a video of a BMW engine with horizontal drain plug, that one is a real mess because the oil shoot out more than 8-10" and splashed over some cross members. That video was posted here no more than 30-60 days ago. I will try to search for it and post it here later.
You did oil changes for MB, BMW and Audi with a fluid extractor, correct ? Do you like to do oil change that way or getting under the car(after raised it up and put jack stands under it) to drain oil via drain plug ?
I don't mind paying $100 or more for a fluid extractor to be able to do a clean oil change while standing up, especially for vehicles with top mount oil filter.
I always just drove the M5 up on the curb, got under there with the ratchet and opened the door on the underbelly pan, pulled the plug, slid back out and let it drain. Probably a lot faster than using an extractor. The biggest issue was hooking up the laptop and activating the kick solenoids to drain their oil, not getting the oil out of the engine.
