Used a similar product 6 years ago. Two problems,

First, the oil flow is much slower. If you feel the video shows the flow rate is OK, they might use the low viscosity oil. Second, some used oils will remain in the oil pan. This is a physical limitation, unless you can open up the original drain hole and put in a bigger plug.
