You guys are inventing and trying to solve a problem that doesn't exist.
Fill vs. no fill.
It probably and practically makes very little difference.

If you watch this video (https://www.youtube.com/watch?v=zLBgIve1YzY) by the same guy, increased engine wear with having an unfilled vs. a filled filter in startup only happens with lower viscosity oils and does not happen with higher viscosity oils. And it would only happen for a few seconds anyway on the first startup after an oil change.

Either way, your choice, hopefully the anti-drain valve in whatever filter you choose, if you fill it first, will work, and you won't dump a large amount of oil all over the engine and the flloor.

I agree.
But some have even installed pre-oil systems.
In medicine the question is: "Is it really clinically
significant?" I think not.
That is one benefit of Z ownership. You can do
WHATEVER you want to YOUR car.
Unless you are in California.
