I read it as, "you only take an hour during an oil change service?" I usually spend more time then that since it is an opportunity to inspect the whole underside of the car while I have it on jackstands.

As I said, zero knowledge of extractors of any type, so you can tell me whatever you want about how they work. But unless they have a tube that goes all the way down through the line of the oil filter into the bottom of the oil pan (not even sure that is possible - I have no idea of the architecture of most cars, much less the GR86/BRZ), they have to pull at least some vacuum.
By the way, just watched a couple oil extractor videos and I can't think of any good reason to use one, LOL. In most of the videos they left a decent amount of oil in the pan. And believe me, there is a significantly greater than 0% chance you end up dripping (if not spraying) used oil inside your engine bay. Why in the world would anybody do this in favor of couple of ramps???
And speaking of that, if you put your car on jackstands to do an oil change, you and I are already on completely different pages as to what is involved in an oil change.
